An Optimal and Secure Routing Protocol for Wireless Sensor Networks

In this paper, we propose an optimal and secure routing protocol for Wireless sensor networks. Where, the neigh-boring initialization is done using the signal to interference plus noise ratio (SINR). The route finding is optimized by a cost function which combines the remained energy and the traffic load at each node of the network’s paths. All the messages which circulate on the network are secured using the digital signature. The simulation results shown that, the proposed protocol increases the network’s lifetime and decreases the packets loss, especially, when used with the elliptic curve digital signature algorithm (ECDSA) under a 160 bits key.
