Research on node energy balanced consumption algorithm in cluster of wireless sensor networks

In wireless sensor networks, clustering algorithm prolongs works´ lifetime drastically. In a cluster, because the distances are different between member nodes and head node, the energy consumption of member nodes will become unbalanced when they transmit message to the head node directly. The EBCA (energy balanced consumption algorithm) is proposed for the problem. In EBCA, member nodes are divided into 3 layers, and nodes in middle layer and close layer transmit message directly while nodes in far layer combine direct transmission and being relayed by nodes in close layer. Simulation exhibits that EBCA has good effect to the problem.
