BESM: A Balancing Energy-aware Sensor Management Protocol for Wireless Sensor Network

How to efficiently use energy is always one of most important issues in wireless sensor network(WSN) since the limited energy of sensor nodes. This paper presented a balancing energyaware sensor management protocol for WSN, namely BESM, based on PEAS(Probing Environment and Adaptive Sleeping). BESM allots more sleep time to those nodes that have less energy by two key means, i.e. negotiation strategy based on energy and energy saving method of nodes on the edge, therefore assigns system overall energy consumption to all nodes as balancing as possible and increases system lifetime. Simulation results exhibit longer system lifetime with almost same sensing coverage after introducing our scheme than before.
