In view of the limitations of resources

self-organization character and the uncertainty of network topology of wireless sensor networks

a hybrid routing protocol which is made up of planar routing and hierarchical routing based on energy-aware is proposed.The protocol can determine current state of node and routing selection according to the residual energy of the node

and each node in the network transmits data by"best effort"and network communication is carried out by"forced"dynamicly build adaptive cluster head.Simulation results show that the protocol has a higher production rate of cluster head and reliable data delivery rate

and can reduce energy consumption of network more effectively.
