英文摘要	Wireless multimedia sensor networks (WMSNs) differ from the traditional wireless sensor networks (WSNs) due to their characteristic of directivity. In this work, by analyzing the virtual potential field-based algorithm, which can not really describe the coverage overlap of the node, we propose an electrostatic field- based coverage-enhancing algorithm (EFCEA). Firstly, we build the virtual field and grid in the sense sector and define the grid's number covered by every neighbor as charge and calculate the correlation degree of every neighbor for all sensors. Secondly, redundant sensors are shut off if their gird are wholly covered and waked up according to correlation degree to 'die out' sensor, coverage of networks can be enhanced although large numbers of redundant sensors are shut off by their 'centroid' point revolving round the sensor under the repel force based electrostatic field. Simulation results are presented for demonstrating the effectiveness of our approach. ©2009 IEEE.
