In allusion to the researches of AODV routing protocol mainly based on theory analysis or simulation, this paper researches on the architecture of ARM platform and the operation mechanism of AODV routing protocol, and proposes a new method of porting AODV routing protocol to ARM platform. The verification environment containing four actual nodes is set up. The new AODV routing protocol is running in it. And the technique is a useful reference for porting AODV protocol on ARM platform.
