An Energy-Balanced Relaying Communication Protocol Based on Power and Distance Cooperation

Wireless sensor networks (WSNs) composed of a large number of cheap microsensor nodes with limited battery power and highly correlated collected data is intelligent and autonomous system for measure and management. To reduce the redundant data among the nodes and consequently prolong networkspsila lifetime, clustering protocols which perform application-specific local data aggregation have been put forward. To balance energy consumption in the whole network, in this paper, we propose and analyze energy-balanced adaptive clustering hierarchy (EBACH) protocol, a novel approach adding a new kind node called relay-node besides cluster-head and cluster member node. Simulation results demonstrate that our energy balancing mechanism can obviously improve the system performance compared with general clustering protocols.
