目前采用虚拟力方法解决传感器节点部署问题的算法均基于同构传感器网络,面向异构传感器网络的部署需求,提出扩展的虚拟力算法.该算法采用概率感知模型,部署时根据感知半径的悬殊采用静态部署与动态部署相结合的策略,根据节点感知半径差异度决定最佳距离的取值,节点移动时采用接替移动法.仿真结果表明该算法能够根据应用需要将异构传感器节点合理地部署于目标区域内,同时能有效地均衡网络节点的能耗,延长网络的生存时间.
At present, all the algorithms that use virtual force method to solve the sensor node deployment problem are based on the deployment requirements of heterogeneous sensor networks and heterogeneous sensor networks, and an extended virtual force algorithm is proposed.The algorithm uses probability perception model, Static deployment and dynamic deployment, the optimal distance is determined according to the difference of perceived radii of nodes and the move-by-move method is used when the node is moving.The simulation results show that the algorithm can deploy heterogeneous sensor nodes reasonably in the Target area, at the same time can effectively balance the energy consumption of network nodes to extend the network’s survival time.
