Abstract: Based on linear distribution, multi destination nod and bidirectional information transfer of freeway weather monitor wireless sensor network, this paper proposes a bidirectional routing protocol based on directed diffusion. The simulation proves that this bidirectional routing protocol is easy to be implemented and stable in working, and it can satisfy the demand of bidirectional information transfer of freeway weather monitor wireless sensor network.

Key words: wireless sensor network, routing protocol, directed diffusion
