Zhou Si · Chinese Journal of Computers · 2007
Mobile agent is more suitable for wireless sensor networks than the C/S model in data fusion.In mobile agent based data fusion,the order of nodes visited along the route by mobile agent has a significant impact on the algorithm efficiency and life time of wireless sensor networks.This paper proposes a trajectory-based mobile agent dynamic route scheme for data fusion in wireless sensor networks.By designing data packet and data table with specific structure,the OBIC algorithm is first presented to obtain an optimal path between object nodes and processing element.Then an optimization problem of mobile agent static route is formed and the MASR algorithm is introduced to solve the optimal static route.The MATDR algorithm is finally presented to obtain a mobile agent dynamic route.Theoretical analysis and experimental results show that the proposed scheme is able to provide less energy consumption and network delay compared to other schemes.
