Research on Routing Protocol for Wireless Sensor Network

With the rapid development of computer technology,wireless sensor network (WSN) is widely used in many fields of society, This paper introduces the characteristics of wireless sensor network and its routing protocol. Based on the hierarchical model, a dynamic selection of the sink node and the hierarchical model of multipath routing protocol is proposed which can balance the energy consumption of nodes, and it also can prolong the network lifetime, improve the data transfer rate.
