随着传感器技术大量应用于安防、监测等领域,覆盖成为了无线传感器网络的一个基本问题,反映了网络监测和实现目标跟踪的质量效果。本文主要针对传感器节点初始覆盖有约束条件的情况,研究了确定性区域传感器覆盖问题。提出了基于约束遗传算法的覆盖机制。仿真结果表明该算法能快速收敛于最优解,完成有约束条件的传感器初始覆盖,从而实现传感器网络的快速优化覆盖。 As sensor technology is widely used in security and surveillance, coverage has become a basic problem of wireless sensor network, which reflects the quality of network monitoring and target tracking. In this paper, we mainly deal with the case of sensor node initial coverage constraints, and study the problem of sensor coverage in deterministic regions. A cover mechanism based on constrained genetic algorithm is proposed. The simulation results show that the algorithm can quickly converge to the optimal solution and complete the initial coverage of the sensor with constraints, so as to realize the rapid optimization coverage of the sensor network.
