The Research Of Wireless Sensor Network Routing Protocol Based On The Energy Efficient

The sensor technology, microelectro-mechanical systems and wireless communications have motivated the development of wireless sensor networks in recent times。Wireless sensor netwrork consisting of lots of snesor nodes which form a multi hop self-organize network system through wireless communication。The information which happened in the network cover area was collect,sensor,deal used by the system and then send to the observer。Wireless sensor network is being used in a wide of variety of commercial and military applications and become a new research area of modern technology。The number of sensor node in WSN are numerous and single node is limited in resource and the resource can't be replaced。The all-important aim of designing routing protocol of WSN is to reduce the overall energy dissipated in the network and maximize the network lifetime。In this paper,first, we gave a summary of the history of Wireless Sensor Network and some applications of Wireless Sensor Network。And we had to face the technical difficulties and challenges in the future。Second,we have an overview of structure of the wireless sensor network。Then analyze the feature of wireless sensor network。Third,we gave the classification of the routing protocols for wireless sensor network。At the same time we had listed and made comparsion of several kinds of existing protocols。At last,introduces a new strategy of cluster-heads election based on the LEACH protocol。The Simulated annealing algorithm was used to optimal the cluster in the first round and the remaining energy and position of the sensor node were taken as the parameter to optimze the porcess of cluster-head selection。It avoid choosing nodes with lower residual energy and bad position as cluster-heads and provide the energy load's proportionality of sensor node。And analyst the energy comsumption by the new strategy of cluster-heads election。The simulation results on Network Simulator 2(NS2) show that the new strategy of cluster-heads election achieves great advance in sensor and network's lifetime compared with the LEACH protocol。...
