Energy independent clustering routing algorithm for wireless sensor network

Abstract

The constraint conditions and life time issue is analyzed through network optimization model. In this paper, the distribution of cluster head is uniform, the nodes in the cluster employ 1-hop to communicate with cluster head, and the cluster heads use multi-hop and the minimum energy to communicate and transmit data with the sink node. An energy independent cluster routing (EICR) is put forward to overcome the drawbacks of LEACH. In the proposed algorithm, the node with higher ratio of remaining energy has the higher priority to be the cluster head. Numerical simulation results show that the obtained approach can enable node with the same remaining energy, balance the node's energy, and effectively extend the network lifetime.
