Popis: Mobile sensor networks consist of a set of mobile sensor nodes, which establish wireless communications within a specific area. In WSNs, mobile sensor nodes can sense the physical status of a given environment, process information and report them to the sink node or the base station. Due to nodes’ movements, these networks do not have a fixed infrastructure. There is no centralized controlling infrastructure for wireless sensor networks and different nodes are at relative liberty for joining and leaving network. Furthermore, due to the specific applications of these networks, it is highly probable that malicious nodes may exist in the network. The available malicious nodes in these networks do not follow the general principles, which dominate the execution of the routing protocols. They make hostile changes and abuse the rules, so as to disrupt the normal functioning of the routing protocols. In this way, malicious nodes aim to demolish the network or they refuse to cooperate fully with other available nodes in the network so that they can preserve their own limited energy. Consequently, they would like to destroy the possibility for providing services for some users. In order to ensure routing security in sensor networks and consider their fundamental challenge, i.e. nodes’ optimal power consumption, we proposed clustering-based secure routing protocol by capitalizing on willow butterfly algorithm. It has three phases, i.e. clustering, encryption and routing. The results of simulating the proposed method using OPNET showed its better performance in terms of power consumption, data transmission delay and access delay to media, data-packet loss rate by destructive nodes and productivity rate.
