Application Research Of Agent Technology In Wireless Sensor Network

Wireless Sensor network (WSN) is an emerging area of computer science, driven by advances in Micro Electro Mechanical System (MEMS), nested computation, networks and wireless communication technologies. WSN is constructed by small, low-cost and low-power sensor nodes deployed in large quantity, and it is self-organized network in wireless multi-hop mode. WSN can be used for sensing, collecting and processing information of monitored objects and send information to the user. WSN is a novel technology about acquiring and processing information, which has a wide application future. Both academia and industries are very interested in it.The node of the wireless sensor network often uses batteries to supply electricity, but the electricity energy in the batteries is limited, meanwhile the communication, calculation and storage abilities of the node are limited, which raise challenges to the hardware and software design of the wireless sensor network. This thesis, basing on this background, points out the use of agent technology in wireless sensor network.Firstly, the thesis introduces the background, definition, construct and correlative theories of wireless sensor network and agent technology. Secondly, the thesis analyses the traditional client sever mode according to the usage requirement of the wireless sensor network. The traditional client server mode transfers the data to the processor center to process, which is not suitable for the distribution environment of the wireless sensor. On the contrary., the mobile agent based calculation mode transfers the data to the local node. Its advantages and characteristics are in accord with the requirement of the wireless sensor net work. Therefore, we put forward the use of the mobile agent based calculation mode in the wireless sensor network, and carry out analysis and design accordingly.Finally, considering the similarities of the wireless sensor network and multi-agent system as well as the advantages of mobile agent and multi-agent, the author put forward the designs of the multi- agent system mode of the wireless sensor network, illustrates the function of the component in the mode, and verifies the feasibility and validity of the theory by simulated experiment.
