The network integrates sensor technology, embedded computing technology, distributed information processing and communication technology which can be real-time monitoring, sensing and acquisition the information of various environmental monitoring or targeting object within regional of distribution networks. Such information will be processed and transmitted to the user. Wireless sensor networks are widely used in military, industrial, transportation, security, medical, detection, family and office environment. The research, development and application of it relates to national security, economic development and other important fields. In recent years the wireless sensor networks have been caused much attention and investment. External uncertainty environment often leads to hundreds of sensors shall be deploymented to work together, so the large-scale sensor networks research is gradually aroused widespread interest and considered a challenging research topic of this century. Against the above problems, the academic research mainly concentrated in the sensor clustering algorithm, communications routing protocols, network coverage and sensor data fusion technology. LEACH algorithm is a typical
