Heterogeneous Energy Adaptive Coverage Control Protocol in Wireless Sensor Networks
Xiaofeng Zhou · 2009
Sensing coverage and energy consumption are two primary issues in wireless sensor networks.Sensing cove-rage is closely related to network energy consumption.The performance of a sensor network depends to a large extent on the sensing coverage,and its lifetime is determined by its energy consumption.A Heterogeneous Energy Adaptive coverage control Protocol for wireless sensor networks(HEAP) was proposed.Adopting the hierarchical clustering idea,HEAP elects the working nodes based on the average residual energy of neighboring nodes and its own residual energy parameters.Simulation study and analysis demonstrate that HEAP not only provide the high quality of sensing co-verage,but also has the good performance in the energy efficiency.In addition,HEAP can better adapt the applications with the great heterogeneous energy capacities in the sensor networks,as well as effectively reduce the control overhead.
