Direct select mobile agent algorithm in WSN query

Mobile Agent algorithm (MA) has defects of multiple query efficiency and nodes´ utilization. To improve it, connect with the direct diffusion algorithm, a direct select mobile agent algorithm (DSMA) in WSN for multiple tasks was proposed on the research of MA. The DSMA can adjust the agent nodes for the query tasks that can reduce the delays when there were multiple tasks running in WSN. Which means it can improve the query efficiency, and also, it can increase the service life of the whole network. At the end, the simulation shows that the algorithm can be useful.
