Wireless sensor networks, network generation with high potential in the field of the most unpredictable and dynamic environments .. However, this network because of its open media, Changing and dynamic topology and routing algorithms is fragile. Ad hoc networks and wireless networks support different features, such as dynamic self-organizing, self-configuring, self-correction, high scalability, easy maintenance and reliable services, Despite its many features already mentioned, this network is very susceptible to damage from attacks. The absence of a central control system known weakness is perhaps the most important reason. Hierarchical dynamic network topology also allows the implementation of security mechanisms disclaims grid design. By reliable way to offer solutions that can change the nature of attacks against network node that is a dangerous counter attack in this area and to restore network . Characteristic features of the method, computational overhead and minimal power dissipation on the one hand and preventing attacks on the network works. Strategy and the proposed mechanism is evaluated using the simulator NS2.
