An Efficiency Measure Approach for Wireless Sensor Networks

Due to limited resources in wireless sensor networks (WSN), monitoring the residual energy of sensor nodes or average area energy is very important, but not enough. Exhaustion of one node won´t lower the average energy of the region notably, but the efficiency of information exchange within that area may be affected obviously. In this paper, an efficiency measure approach for WSN is proposed to measure the efficiency of information exchange based on the residual energy and energy consumption balance. The proposed approach utilizes the small world characters of clustering WSN. Simulation results show that the energy-balance measure approach has advantages in measuring the efficiency of information exchange in WSN.
