Abstract:
In many wireless multimedia sensor networks (WMSNs) the nodes are static. However, node connection is subjected to change due to disruptions in wireless communication, power changes in transmission, or loss of synchronization between neighboring nodes. A sensor should constantly be aware of its immediate neighbors, through a process called continuous neighbor discovery. In this paper we introduce an energy efficient hidden node detection (EEHND) algorithm for continuous neighbor discovery process in the wireless multimedia sensor networks (WMSNs). We focus on the continuous neighbor discovery process and regard it as a combined task of all the nodes in every connected segment. Each sensor is entered as a coordinate in an effort in order to reduce the time to detect hidden sensors. Based on the simulation results, we demonstrated that the protocol detected the hidden nodes in the network.
