        Resource allocation has always been one of the main challenges in the design of wireless cellular networks. Suitable resource allocation, more specifically that includes suitable base station selection and bandwidth allocation can play an effective role in interference mitigation and users’ quality of service requirement satisfaction. In this paper, a game theoretic approach is proposed to solve the BS selection problem in two-tier wireless femtocell networks. We formulate the competitive behavior of users as evolutionary game theory. We calculate the probability of a user choosing a BS, compute the cell load of each BS, and analyze the demand rejection probability of the user associated with the BS. The proposed approach maximizes network throughput as well as meeting the QoS requirements of the users. Finally, we propose a decentralized learning algorithm based on EXP3 algorithm to achieve the evolutionary equilibrium as the solution of the game. Simulation results show that the proposed approach achieves a desirable performance and guarantees users’ QoS requirements. Manuscript profile

        Introduction: The aim of this paper is to investigate the effect of Six Sigma process management on improving the quality of health information services and reducing treatment costs. Research Methodology: The methodology of the present study, which is among the applied studies in terms of purpose, has been a descriptive survey of the type of correlation. The statistical population of this study consists of all managers, supervisors and experts of Farhikhtegan Hospital, which is 125 people. The Cochran's formula has been used to determine the sample size, which is 94 people according to the statistical population. The method of selecting statistical samples is also a simple random sampling according to the subject and nature of the research. The required data were collected using standard questionnaire tools and data analysis using regression analysis through SPSS 23 software. Results: The management of the six Sigma process through the mediating variable of the quality of health information services has an impact on cost reduction. Therefore, the mediating role of quality of health information services is confirmed. Conclusion: Six Sigma provides a systematic approach to improving business processes based on customer needs and real-time analysis of ongoing processes in each institution. This is the difference between Six Sigma and other methods and the main reason for using it in health care institutions. Regardless of these differences, the implementation of any approach requires the establishment and acceptance of a culture of quality in that organization. Manuscript profile

        Objective: The aim of this study is to determine the quality level of services of Hamedan Medical Sciences University libraries through gap analysis. Method: This study is applied based on survey – analytical method which evaluates the quality of provided services by means of the questionnaire a“I.A. LibQual”.  The population of this study consists of the active users of Hamadan Medical Sciences University libraries based on a random stratified sampling, using the Kerjcie and Morgan,which a sample size equal to 367 persons was obtained. Results: The quality level of services provided by the libraries equals to 2/987 according to the users; and these libraries have, in general, been able to meet the minimum expectations of the users and there is a big gap for them to reach the goal of meeting the whole expectations of the users. From the users’ perspective, the scopes of “hiring”, “staff” and “information station” have received the highest degree of preference and importance respectively. And “publication”, “press” and “audiovisual resources” received the lowest level of importance. On the other hand, the result of the first five hypotheses show that from the users’ perspective, there is a meaningful importance between the level of importance of the basic five main components of quality and the performance level. Conclusions: The gap between the level of importance and the quality level of current services in five components is negative. In other words, to achieve the level of users’ satisfaction and to increase the quality of existing services, Hamadan Medical Sciences University libraries need more effective planning and efforts.

        The purpose of the present study is to review an estimation of customer lifetime value (CLV) based on quality of services provided by Mashhad body building gyms. The research method was correlational description and it had an estimation approach. The Research statistical population consisted of those who enrolled in body building gyms in Mashhad for at least 6 months, among whom 384 members were studied in different gyms ranked from 1 to 3 with respect to their cooperation and accessibility. The research instruments consisted of 2 standard questionnaires including Services Quality by Parmason et al. (1985) and Customer Lifetime Value by Vow Vali (2011) which were distributed among the customers in the gyms through a stratified way.  SPSS and LIZREL software programs were used for data analysis. The results showed that by 95% confidence level it can be said that quality of services provided by the gyms can have a significantly positive effect on CLV while no significant correlation was observed between CLV and ranking of the gyms. On the other hand, quality of services and ranking of the gyms have a significant impact on CLV. Therefore, it is recommended to the directors of the gyms to pay more attention to the components which enhance service quality and ranking of their gyms.   Manuscript profile

        Introduction: Enterprise networks are increasingly becoming larger and more dynamic due to vast deployments of virtualization technologies. Consequently, the explosion of new network applications and services has strained the capabilities of traditional networking architecture in terms of scalability, agility, and efficient traffic management. SDN (Software Defined Networking) is a novel approach to build networks in which control logic is decoupled from data forwarding in order to enable programmability and ease of configuration across the entire network. The centralized control in SDN provides a global view of the entire network resources and their performance which enables the innovation of new service models. This paper demonstrates the implementation of SDN in a sample data center network topology using Mininet and the RYU controller, followed by employing policy-based network management and a differentiated service mechanism for guaranteeing the QoS for different classes of traffic. The proposed framework is a foundation to develop an enterprise-level network control and management product. Method: The approach of this paper is an implementation of a software-based architecture in the topology of a data center. It manages and guarantees the quality of service, using network policy-oriented management and service quality methods. The presented framework is an expandable infrastructure to solve the challenge of dynamic and agile management in the network of data centers and virtualization and cloud processing service providers.Findings : With the implementation done, h1r1 server node listens on ports 5001, 5002, 5003 with UDP protocol. The h1r4 client node sends 1Mbps UDP traffic to port 5001, 300Kbps UDP traffic to port 5002, and 600Kbps UDP traffic to port 5003 of the h1r1 server. The results obtained using the IPerf3/JPerf tool show that for traffic marked with AF41 code sent to port 5003, minimum bandwidth of 500Kbps and for traffic marked with AF31 code sent to port 5002, minimum bandwidth of 200Kbps is guaranteed. Is. When sending traffic of AF classes, the bandwidth of the best-effort traffic sent to port 5001 is limited.Conclusion: Guaranteeing full quality of service for all types of applications is not possible with the current network architecture based on the best-effort model. Different applications have different service needs that require dynamic management of network resources. In this article, a solution based on SDN architecture was presented for service quality management, which uses a differentiated service model. Differentiated service mechanism allocates resources based on different traffic classes. In this method, all streams belonging to a class are routed equally. The results obtained from the simulations show the optimal performance of the introduced framework in meeting the needs of traffic flows and optimal and maximum use of network resources.

        The multi-path transmission is an appropriate transmission method for high data rate packets like video streaming. To provide video streaming with high quality, the video packets are divided into different frames for transmitting through various paths. Nevertheless, regarding the results of numerous inherent features of vehicular ad-hoc networks (VANETs), designing an efficient and stable routing protocol is difficult for various applications of VANETs. In particular, the dynamic nature of topology and intermittent connectivity make maintaining the quality of service (QoS) task very difficult. To provide QoS to entertainment applications and traffic safety in VANET, we offer a routing protocol based on the adaptive intersection with QoS support regarding delay, packet delivery ratio (PDR), and connectivity probability. To establish the best QoS routes, we considered the equivalent routing problem as the optimization problem and then proposed an algorithm based on ant colony optimization (ACO) for solving it. Furthermore, a fuzzy logic-based algorithm was employed to select the best next-hop vehicle by incorporating multiple metrics associated with the vehicle’s position, link quality, and vehicle mobility. According to the simulation results, the proposed approach achieves the average PDR of more than 84.2%, the end-to-end delay of less than 3.58 s, the overhead of less than 15.65%, and the peak signal to noise ratio (PSNR) of more than 20.82 dB. It is understandable from the result analysis that the performance of the proposed approach is excellent. Manuscript profile

        The internet of things (IoT) faces various challenges due to its different characteristics and due to the nov­elty of related technologies and standards. The existence of these different and at the same time new problems has drawn the attention of many scientific researchers toward this new technology. One of the most important and fundamental challenges is related to the topic of routing protocols in static and mobile networks, and more precisely, optimizing and improving the quality of service of it. In this work, a novel flexible, scalable, and efficient routing protocol named MLOADng-AT (mobile lightwe­ig­ht on-demand ad hoc distance vector routing protocol– analytic hierarchy process echnique for order of preference by similarity to ideal solution) has been introduced to overcome the routing challenges in mobile scenarios. Using MLOADng-AT, firstly, taking advantage of the HELLO message, infor­mation about link quality parameters and mobility characteristics up to two hops is exchanged among static and mobile nodes. Moreover, it supports an error recovery path without rerunning a new routing process that noticeably decreases the network routing delay. MLOADng-AT can be easily adapted to any quality of service (QoS) parameter with very low complexity which is very important for a delay-sensitive IoT-based network. Finally, in case of noisy conditions especially for mobile networks, the proposed protocol can be efficiently used in low-quality links. Simulation results based on several scenarios depicted that end-to-end delay (EED) and packet delivery ratio (PDR) parameters significantly improved in the proposed method compared to other similar methods. For the area with dimensions of 400 x 200 m2, the obtained values of the EED and PDR parameters are respectively 0.0011 seconds and 98.47%, and also for the scenarios implemented in the area of 800 x 400 m2, the achieved results of the EED and PDR parameters are respectively 0.0059 seconds and 86.167%.

        Quality of Service (QoS) provisioning is very important in next computer/communication networks because of increasing multimedia services. Hence, very investigations are performed in this area. Scheduling algorithms effect QoS provisioning. Lately, a scheduling algorithm called Regulated Burst Service Scheduling (RBSS) suggested by author in [1] to provide a better service to bursty and delay sensitive services such as video. One of the most significant feature in RBSS is considering burstiness of arrival traffic in scheduling algorithm. In this paper, an upper bound of queue length or buffer size and service curve are calculated by Network Calculus analysis for RBSS. Because in RBSS queue length is a parameter that is considered in scheduling arbitrator, analysis results a differential inequality to obtain service curve. To simplify, arrival traffic is assumed to be linear that is defined in the paper clearly. This paper help to analysis delay in RBSS for different traffic with different specifications. Therefore, QoS provisioning will be evaluated. Manuscript profile

        Computational Grids have developed as a new approach to solve large scale problems in scientific, engineering and business areas. Open Grid services architecture is an adaptation of the service-oriented architecture which presents the Grid operation a set of service-oriented softwares. Grid services composition provides the possibility for users to submit their complex requirements as a single request.QoS-aware Grid service composition algorithms try to construct a composite Grid service which satisfies the user-defined constraints as well as to optimize the QoS parameters. All of the presented service composition approaches in the literature discard using the Grid services with unknown QoS values in the composition process. However, estimation of unknown QoS values of Grid services provides an opportunity for them to be selected as component Grid services in the constructed composite service. In this paper, a probabilistic QoS model is presented for estimating the unknown QoS values using Bayesian network. Experimental results indicate that estimating the unknown QoS values has high accuracy and leads to more efficient composite Grid services. Manuscript profile

        Abstract – Joint bit allocation, relay selection and subcarrier assignment are critical for achieving full benefits of OFDM-based cooperative relay networks. In this paper, first such a problem is studied in a dual hop OFDMA cooperative network consisting in multi source nodes, multiple decode-and-forward (DF) relays and a single destination node. The aim is to minimize overall transmission power under the bit-error-rate (BER) and data rate constraints. However, the optimal solution to the optimization problem is computationally complex to obtain and may be unfair. Assuming knowledge of the instantaneous channel gains for all links in the entire network, an iterative three-step resource allocation algorithm with low complexity is proposed. It performs the privileged user selection based on fairness criterion first, and then allocates subcarrier-relay with the given constraints. Finally, power and bit are assigned to the selected subcarriers based on the water-filling algorithm. In order to guarantee the fairness of users, several fairness criteria are also proposed to provide attractive trade-offs between network performance (i.e. overall transmission power, average network lifetime and average outage probability) and fairness to all users. Numerical studies are conducted to evaluate the performance of the proposed algorithm in two practical scenarios. Simulation results show that the proposed allocation algorithm achieves an efficient trade-off between network performance and fairness among users. Manuscript profile
