Abstract :

Routing with energy consideration has paid enormous attention in the field of wireless sensor networks (WSNs). Aiming at maximizing network lifetime in WSNs, most studies focus on min-imizing energy consumption. Energy is consumed by sensor nodes to perform three important functions such as data sensing, transmitting, and relaying. Also, event-driven WSN applications require minimum end-to-end delay and medium access delay. This paper proposes an energy-efficient fuzzy logic-based fault-tolerant routing protocol (EEFRP) for routing in WSN and min-imizing the energy consumption to a large extent. EEFRP takes two important parameters “resid-ual energy” and “hop-count” into consideration. Simulation results demonstrated that the pro-posed algorithm could achieve better performance in comparison with IEEE 802.15.4 original protocol in terms of end-to-end delay, medium access delay, and fault tolerance, particularly in node failure cases.Routing with energy consideration has paid enormous attention in the field of wireless sensor networks (WSNs).
