The wireless sensor network (Wireless Sensor Network: WSN) is the large number of sensors in the monitoring area by the arrangement formed by the node through the wireless communication method of a multi-hop ad-hoc network system, its purpose is collaboration perceive, acquisition and processing of network within the coverage area the object information to be monitored, and sent to the viewer. WSN With the development of sensor technology, embedded computing technology, distributed information processing technology, communication technology and micro-motor technology industry and the rapid development of great value in military, industrial, medical, transportation, environmental protection and other aspects . Determine the location of the incident location or gathering data node is one of the basic functions of the sensor network, wireless sensor networks, the node localization problem is the key technology in wireless sensor networks and research focus. This thesis studied some of the basic theoretical knowledge of wireless sensor network node localization, and then propose a wireless sensor network localization algorithm based on the RSSI-GA stationary nodes, Finally, we propose an improved Monte Carlo mobile node localization algorithm. First, wireless sensor networks, the node localization basic knowledge and some of the typical positioning algorithm, including stationary node positioning algorithm with a mobile node localization algorithm. Then, explore the RSSI wireless sensor network positioning algorithms and genetic algorithms to analyze the advantages and disadvantages of the algorithm, based on the practical problems of the wireless sensor network positioning based the RSSI-GA stationary node positioning algorithm, RSSI-GA location algorithm based on RSSI theory to compute nodes the distance between the use of the improved genetic algorithm to carry out the positioning of the nodes, the simulation experiment the feasibility and advantages of the algorithm from the theoretically analyzed, and finally the proposed algorithm, and the simulation results to be compared with the existing algorithms , the proposed algorithm can be seen that exhibit superior performance. Finally, in-depth study of the MCL the mobile node localization algorithm analysis algorithm strengths and weaknesses, improved MCL mobile node localization algorithm. This algorithm makes use of the anchor box \Improved algorithm simulation experiment with basic MCL algorithm, simulation results show that the improved algorithm has better performance, improved positioning accuracy.
