A Performance Evaluation of the Coverage Configuration Protocol Under Location Errors, Irregular Sensing Patterns, and a Noisy Channel

Area coverage problem is one of the key issues to prolong a wireless sensor network lifetime. It is based on selecting as few active nodes as possible from all deployed nodes while maintaining sufficient sensing coverage of the monitored region. Several area coverage protocols have been proposed, most of them assume the availability of accurate information about node locations and sensing ranges. Relaxing these conservative assumptions might impact the performance of area coverage protocols. In this paper, the authors study the impact of location errors, irregular sensing ranges and packet losses on the coverage configuration protocol. They focus more precisely on their impact on the number of selected active nodes, the coverage ratio and the total consumed energy.
