Wireless sensor network routing protocol the primary goal of designed is to effectively save energy and prolong network life cycle. This paper focuses on the studies of wireless sensor network routing protocols and do some work. First,we described the concepts of wireless sensor networks,such as features and architecture of wireless sensor networks,etc.we focused on wireless sensor network routing protocols, and detailed the AOMDV protocol and LEACH protocol.By agreement with the AODV protocol AOMDV simulation comparison,analyzed the average delay,packet delivery ratio and throughput performance of the AOMDV,but also analyzed LEACH protocol on energy-saving. Second,we introduced a wireless sensor network MAC layer protocol, gave a detailed analysis of the SMAC protoc
