无线传感器网络节点部署算法的优化研究

摘要

The deployment of wireless sensor network is researched. Sensor nodes near to stations transmit other nodes and consume more energy in wireless sensor networks, resulting in energy hole and causing the network life energy prematurely. In order to avoid the energy hole and prolong the network life - time, a nodes deployment algorithm is proposed. The optimal algorithm uses the number of nodes deployment scheme, the optimal node, the transmission distance as constraints, and maximum efficiency as the optimum target network. Simulation results show that the proposed method can not only avoid energy hole, but als improve the deployment rate effectively compared with the tradifional method. The proposed method can save the network efficiency and prolong the network life cycle.%研究无线传感器网络的部署.无线传感器网络中靠近基站的传感器节点因需要转发其它节点的数据而消耗更多的能量,导致出现能量空洞,使网络生命过早地结束.为了避免能量空洞的形成,延长网络寿命,提出一种高效的节点部署算法.算法以最优工作节点数、中继节点部署方案和节点传输距离作为约束条件,以最大网络效率为优化目标进行研究.仿真结果表明,方法不仅能够避免出现能最空洞,而且比传统的部署方法节约能量,有效提高网络效率,延长网络生命周期.
