Abstract	The Coverage Control Technology is the one of the basic technologies of wireless sensor network, and is mainly concerned about how to prolong the network lifetime on the basis of meeting user sense demands and network connection. Among this technology, localized area coverage algorithm in the study of area coverage technology is gradually attracting wide attention, for its less traffic and lower single-node computation. However, most of the existing localized area coverage algorithms are mainly concerned about how to improve the perceived quality to coverage full area, ignores further studying for the network node connectivity. They maintain network connection by meeting connectivity critical condition proposed by Xing. But, the critical condition is from the view of single node connectivity, resulting in limited conditions for algorithm application. So, standing on the view of the overall network, the loose connectivity critical condition to ensure coverage and connectivity is proposed by us in the previous work. In this paper, based on the loose connectivity critical condition, a circle intersection localized coverage algorithm to maintain connectivity is further designed. By using the connected coverage node set, it can maintain network connection in the case which loose condition is not meet. Simulation results show that the algorithm can maintain network node connectivity on the basis of ensuring full area coverage.
