An Optimizing Movement Control Strategy for Mobile Sensor Networks

Movement control strategy and sensor network deployment are very challenging due to random distribution movement of sensor nodes for mobile sensor networks (MSN), optimization algorithm is becoming a main solution to movement control strategy in MSN. In this paper, an optimizing movement control strategy is proposed for mobile sensor networks. The multilayers mobile sensor network architecture is proposed, then we designed virtual rectangle grid partition deployment scheme of F nodes, to implement the optimizing movement control strategy base on simulated annealing-PSO algorithm for the sensor nodes in the networks. Simulation results show that our approach can improve the network coverage rate, effectively solve the defects of instable communication and the low utilization ratio of the neighbor nodes caused by random movement of sensor nodes.
