A Study of Mobile Agent Tree Routes for Data Fusion in WSN

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 lifetime of wireless sensor network. In this article, we propose a mobile agent tree routes scheme with data fusion. Considering the energy level of the sensor nodes, we construct the data fusion tree based on mobile agent to let mobile agents visit the low battery nodes less frequently, and on the contrary, nodes which have more energy will be visited more, mobile agents execute the data fusion in some nodes while mobile agents are moving. The experimental result shows, with the increase of the network scale and the amount of the sensor nodes, our proposed algorithm has less energy consumption and network delay.
