Simulation of Coverage Problem Research in Wireless Sensor Networks Based on Energy Saving

Power control is an important issue during the research of the wireless sensor networks. Due to the operation of the sensor relies to the battery, so the longevity of the battery controls the longevity of the sensor, even the longevity of the whole sensor networks. The research based on the SCC(Sponsored Coverage Calculation) makes improvement, putting forward the judgement method of improving distributed Coverage sensor. Simulation results show that the method can be more than covered by SCC to identify the node. In the presupposition of taking the integrity of monitoring range into consideration, our methods can achieve the purpose of a more energy conservation and a longer network lifetime.
