Executive Summary

The limitation of energy supply is a crucial problem in wireless multimedia sensor networks. In this paper, the authors research and optimize the energy utilization during data collection by adopting mobile agent nodes. First, they demonstrate that the energy consumption of the whole network is affected by the data correlation coefficient for a multimedia sensor network with a random node deployment. Then, they give the method to find the optimized position of mobile agent node for maximizing the energy-saving efficiency by fusion process. Finally, they propose an Energy Efficient Fusion-driven Routing (EEFR) based on cluster hierarchy. To obtain a better performance, the cluster structure is divided based on square grid topology.
