无线传感器网络及其路由协议研究

Since micro-electronics, computer and wireless communication made progress, wireless sensor network has got rapid development and become the focus of Information Technology field. Because of the restrictions on self conditions and deployment environment, it puts forward high demands for energy utility efficiency, network lifetime, fault-tolerant and expansibility. Routing protocol is the pivotal research subject in network layer of wireless sensor network. First of all, this paper introduces the conception, application scale, situation and framework. Then, it expounds the classification and designing desire of routing protocol of wireless sensor network, and analyses several representative routing protocols.
