Research Of Routing Protocols In Wireless Sensor Network And QoS

Wireless Sensor Networks are new network technology, which integrate sensor, low-pow communication and micro-electro-mechanical technology. These nodes have many specific features, namely, densely distributing in working field with random location and self-organization ability; locally processing data collected from physical world; adaptive collaboration with other nodes for data routing and transmission. Self-organization and fault-tolerance of Wireless Sensor Networks are quite fit for military control, communication, monitoring and spying. Wireless Sensor Networks have become a hot issue with features of low-cost, low-power and multifunction.The basic situation and current condition of Wireless Sensor Networks are introduced. Routing protocol of Wireless Sensor Networks and QoS metric, and propose the main problem of our work based on those investigations are analysed. The central problem of this article is how to satitisfy QoS requirements of WSN routing in order to improve performance of routing algorithm. Finally, it implement routing algorithm based on simulation. Experimental results show that the routing protocol is correct and efficient. They can satisfy QoS requirements of WSN.
