An overview of routing protocols on Wireless Sensor Network

Routing protocols is one of the key technologies in Wireless Sensor Network (WSN). More and more studies focus on the connectivity and secure communication between nodes in WSN. In this paper, according to the network structure in WSN, we classify the routing protocols into three categories, namely Data-centric protocol, Geographic routing protocol and Hierarchical routing protocol. An overview of routing protocols on WSN is presented in this paper. Then, we discuss the design challenges of routing protocol and research in the future in WSN from the perspective of advantages and disadvantages among each routing protocols.
