In order to effectively solve the wireless sensor network maintenance difficult problem, networking algorithm with better performance is an effective method to solve the problem. The paper presents the architecture of wireless sensor network model and its connectivity is defined, then the paper presents a networking algorithm for wireless sensor networks with good connectivity, and the algorithm is analyzed by simulations. The wireless sensor network that constructed by our algorithm not only has good connectivity performance, but also can protect energy of network nodes and control network power, so it has a bright application prospect.
