A Movement Control Strategy Based on Virtual Repulsion and Aggregation Algorithm in Multi-Tier Mobile Sensor Network

Wireless Sensor Network (WSN) is the hot research topic. In order to adapt to the future development direction of WSN, this paper presented a movement control strategy based on virtual repulsion in Multi-tier Mobile Sensor Network. The strategy first used a hierarchical node aggregation algorithm to divide all sensor nodes into many communication clusters in the monitoring area. It combines virtual repulsive force to distribute nodes uniformity in every cluster. Finally, using aggregation algorithm again based on the nodes uniform distribution to design fusion nodes´ optimal movement route for data collection. The simulation results show that the strategy can ensure the efficiency of network data collection, reduce data loss rate, and nodes power consumption.
