Description

Energy efficiency is a most important constrain in wireless sensor network. In a large area network, it is impossible to each node send the data to sink. It takes more time and hops for transmission and leads to collusion. For achieving the network lifetime in wireless sensor network, we propose new regional aware energy efficient cluster method. Proposes a new regional energy aware clustering method using isolated nodes for WSNs, called Regional Energy Aware Clustering with Isolated Nodes (REAC-IN). In REAC-IN, CHs are selected based on weight. Weight is determined according to the residual energy of each sensor and the regional average energy of all sensors in each cluster. Improperly designed distributed clustering algorithms can cause nodes to become isolated from CHs. Such isolated nodes communicate with the sink by consuming excess amount of energy. To prolong network lifetime, the regional average energy and the distance between sensors and the sink are used to determine whether the isolated node sends its data to a CH node in the previous round or to the sink. The simulation results of the cur-rent study revealed that REAC-IN outperforms other clustering algorithms.
