摘要

基于闲时能量开销优化目标提出了一种适用于异构传感器网络的密度控制算法(DCA)

DCA能寻找到一个闲时能量开销近似最小化的连通覆盖集合

该集合最终映射为活跃节点集合。理论分析和实验数据表明

DCA所生成的拓扑能有效降低网络闲时能量开销

延长了网络的生命周期。

Abstract

The scheme of gradually topology expansion was adopted

and a density control algorithm DCA aiming to reduce the vacant energy consumption was presented for heterogeneous WSN. A connected coverage set based on minimizing vacant energy consumption can be found by DCA

and the set would be mapped into the active nodes set finally. Both theoretical analysis and experimental data suggest that DCA can achieve well-constructed topology and prolong network lifetime effectively.
