col stack, has great influence on the performance of WSN. Because of the limited node energy and storage capacity, how to effectively make use of node energy, to balance the node energy consumption and to prolong the work lifetime is the primary objective when researching and designing the routing protocol for wireless sensor this thesis, the main work is as follows:Firstly, describing the architecture, characteristics, challenges and applications of the wireless sensor , introducing the characteristics of wireless sensor works which is different from the traditional wireless works, and classifying the routing protocols which have been proposed for wireless sensor works. Detailed analysis of several typical working mechanism of routing protocols has been carried out and their advantages and disadvantage have also been
