Secure communication is one of the most critical challenging tasks in multi-hop Wireless Sensor Networks (WSNs). Routing protocols of WSNs are highly susceptible to various attacks, which replay the routing information through the malicious node and steal the identities of the valid nodes in a network. The malicious nodes forward the packets far away from the sink, increasing the packet drop ratio, those overall network efficiency. In order to overcome this problem, they have designed and implemented a Secure Trust Aware Energy efficient Adaptive Routing (STEAR) for dynamic WSNs.
