Mobile-Agent-Based Information-Driven Multiresolution Algorithm for target tracking in Wireless Sensor Networks

In this paper, mobile-agent-based information-driven multiresolution algorithm (MAIDM) is presented for target tracking in wireless sensor networks (WSN), in order to provide better accuracy and degree of fault tolerance while meeting the energy requirement. In a clustered-based wireless sensor networks, mobile agent is used to process data of nodes with multiresolution algorithm according to information contribution of different nodes , and the size of mobile agent is determined by the maximum value of the information contribution along the path of mobile agent. A balance has to be struck between the energy efficiency object and fault tolerance/accuracy object. Simulation results show that MAIDM performs better than IDSQ from perspectives of fault tolerance and accuracy, MAIDM´s energy-efficient performance is better than MA-CSIP.
