Agent based approach to information fusion in wireless sensor networks

Wireless sensor networks are gaining importance because of development in miniaturized sensors. Information fusion is one of the important problem in wireless sensor networks, where data, critical images, etc., are collected from sensor nodes. To have the complete idea of visual world one needs to fuse the information from different sensors. This position paper proposes an agent based distributed sensor network (ADSN) to form an improved infrastructure for multi-sensor information fusion. The proposed scheme is based on the clustering concept in which sensor nodes form the clusters. Each of the cluster has cluster head node. The fusing request will be generated by the user at the sink node by using a mobile agent. The mobile agent roams different active sensor nodes in each of the clusters to perform information fusion based on predetermined signal strength. Finally, once all the relevant nodes have been visited, agent transmits the fused information to the sink node. This work limits the information to only images.
