【摘要】：如今,无线传感器网络广泛地应用在安全监视,生态环境监视,医疗和卫生等领域。优化覆盖控制算法可以节约空间资源,保证良好的服务质量,以确保信息能够有效地传输。无线传感器网络覆盖中一个重要的挑战是节约系统能量,即在高密度部署传感器节点的情境中,保证网络的良好性能,就要使少量节点工作在活跃状态下,其它节点投入低功耗的休眠中。要同时满足覆盖要求(节点必须能够完全覆盖目标区域),又要满足连通性能要求。本文首先研究了无线传感器网络的特点,综述了无线传感器网络覆盖控制问题的研究现状,分析并指出了覆盖控制研究中所需要考虑的问题。基于原有的一些无线传感器网络控制算法,进行算法改进方面的研究。最后,在MATLAB仿真环境下,完成算法的仿真实验,通过对比各种算法的特点,证明改进算法在无线传感器网络覆盖技术上具有能耗小,覆盖率高等特点。
[Abstract]:Nowadays, wireless sensor networks are widely used in the fields of security monitoring, ecological environment monitoring, medical treatment and hygiene. The optimal coverage control algorithm can save space resources and ensure good quality of service. In order to ensure the effective transmission of information, an important challenge in wireless sensor network coverage is to save system energy, that is, to ensure the good performance of the network in the context of high-density deployment of sensor nodes. In order to satisfy the requirement of coverage (nodes must be able to completely cover the target area), a small number of nodes will work in active state and other nodes will be put into low-power dormancy. In order to meet the requirements of connectivity, this paper first studies the characteristics of wireless sensor networks, and summarizes the research status of coverage control in wireless sensor networks. This paper analyzes and points out the problems that need to be considered in the research of coverage control. Based on some original control algorithms of wireless sensor networks, the improvement of the algorithm is studied. Finally, in the MATLAB simulation environment. By comparing the characteristics of various algorithms, it is proved that the improved algorithm has the advantages of low energy consumption and high coverage rate in wireless sensor network coverage technology.
