Abstract: Computing model of nodes has an important effect on the network performance and the mobile agent computing model for the next generation network has attracted more and more attentions. The background of mobile agent applied in the wireless sensor network is first analyzed. Then a framework based on mobile agent is proposed from two levels, namely network and nodes. After introducing the basic elements, functional definitions and interfaces of the framework, an implementation mechanism based on directed diffusion for mobile agent is presented.

Key words: wireless sensor networks, mobile agent, distributed computing model
