Research and Implementation of WSN-based Data Acquisition and Analysis System using Agent Collaboration

摘要

Communication and processing capabilities of a single sensor node in WSN are limited. By integrating data from multiple sensor nodes, WSN is able to complete the task which a single sensor node can not complete. In order to give full play to WSN functions, the sensor nodes need collaboration. Agent and MAS can be regarded as the further development of a distributed problem-solving. The collaboration among agents can improve individual Agent and MAS performance, enhance the agent and MAS'ability to solve problems. collaboration is the core issue in the MAS. In consideration of the similarity of WSN to MAS, agent can be arranged in sensor nodes to solve problems of sensor nodes collaboration. This paper describes in detail the deployment of agents in WSN system, using agent collaboration to coordinate multiple sensor nodes to complete data collection and analysis, and the distributed fault diagnosis. And simulation is carried out in OMNET++ platform with good effect. This paper describes the structure of agent used in this WSN, and introduces the functionality of agents of each node in this system, and overall structure of the system.
