SECURITY AWARE ROUTING FOR WIRELESS SENSOR NETWORK USING HYBRID OPTIMIZATION ALGORITHM

Nowadays, WSN has adopted with more desirable characteristics including self organization, easy deployment, which are more important in modern society. However, prolonging the network lifetime seems to be the most critical problem and hence more works have been done by different researchers. In the view of this issue, this paper intends to propose a security aware routing protocol as the security of network is always a barrier in any applications. In fact, this paper introduces an optimal route selection model via proposing a new hybrid algorithm. Along with the energy consumption, the proposed protocol considers the security of the network in selecting the best route path, which is attained by defining single objective function. Moreover, the proposed hybrid algorithm is the combination of Dragonfly (DA) Algorithm and Whale Optimization Algorithm (WOA) termed as Dragon Updated Whale Optimization Algorithm (DU-WOA). Moreover, the security consideration in the paper deals with the introduction of certain security modes like high security, medium security and risky as well. Finally, the performance of proposed work is compared over state-of-the-art models with respect to delay, energy, packet loss, and throughput, respectively.
