Wireless Sensor Network Routing Algorithm

With the development of the Technology of sensor, compute and wireless communication, more and more devices integrating sensor, communication and processing have been invented and manufactured to accomplish information collection, data process and wireless communication. Wireless Sensor Network consisting of lots of sensor nodes came into being and had been applied in a lot of scenarios and situations. It will be one of the most useful technology for the 21th century. Based on the overview of wireless sensor network, we investigate and analyze the route protocol and arithmetic for wireless sensor network.In this paper we have five sections.In the first section, we gave a summary of the history of Wireless Sensor Network and some applications of Wireless Sensor Network. At last, we had to face the technical difficulties and challenges in the future. In the second section, we have an overview of structure of the wireless sensor network. Then analyze the feature of wireless sensor network. In the third section, we gave the classification of the routing protocols for Wireless Sensor Network. At the same time we had listed and made comparison of several kinds of existing protocols. In the fourth section, we introduce the network simulate platform- NS. Then, the implement of LEACH protocol in NS is presented, including the mobile node's structure, the protocol for MAC and the setting for energy consumption. In the last section, we did some research on the LEACH protocol proposed by Wendi Rabiner Heinzelman. We improved the performance of the LEACH protocol through some adaptation on the algorithm.
