Zusammenfassung

An INSENS protocol is proposed to construct secure Wireless Sensor Networks (WSNs) that prevent attacks aimed at the network layer of WSNs. To achieve these objectives, all nodes which compose the network, send the feedback message to the base station. The feedback message contains the information of all neighbourhood nodes of a sender node. Therefore, if it owns many neighbour nodes within its communication range, then this node sends many feedback messages. This case arouses excessive energy consumption of each node in the sensor network. To solve this problem, we propose a control scheme of the neighbour Information of the feedback message based on the neighbourhood density. To compute the neighbourhood density, we add a new phase that exchanges the count of the neighbouring nodes of each node among the adjacent nodes. We insert this phase between the route request phase and the route feedback phase for improving INSENS. Consequently, all the sensor nodes send a different type of feedback messages by computing neighbourhood density. Through simulation, the proposed method show more efficient energy consumption compared to the original INSENS.
