在无线传感器网络（WSNs）的实际应用中，需要优化网络运行以延长其使用寿命。在此基础上，提出了一种基于集中式集群的无线传感器网络协议开发框架。在此框架下，设计并实现了一种基于音乐的元启发式优化方法——和声搜索算法（HSA）的无线传感器网络实时优化协议。期望最小化簇成员与簇头之间的簇内距离，并优化wsn的能量分布。基于HSA集群协议的研究是在一个真实的案例中进行的，该案例将配备该协议的wsn部署在室内环境中监测环境温度以进行火灾探测。并与低能量自适应聚类分层集中式聚类协议（LEACH-C）和基于模糊c均值聚类算法的聚类协议（FCM）进行了比较。实验结果表明，基于HSA的无线传感器网络可用于建筑环境中的安全和监控应用。从得到的实验测试结果可以看出，与LEACH-C和FCM协议相比，采用HSA协议的wsn寿命得到了延长。
In real-life applications of wireless sensor networks (WSNs), optimization of the network operation is required to extend its lifetime. A framework is proposed that enables practical development of centralized cluster-based protocols supported by optimization methods for the WSNs. Based on this framework, a protocol using harmony search algorithm (HSA), a music-based meta-heuristic optimization method, is designed and implemented in real time for the WSNs. It is expected to minimize the intra-cluster distances between the cluster members and their cluster heads (CHs) and optimize the energy distribution of the WSNs. The study of HSA cluster-based protocol is carried out in a real case where the WSNs equipped with the proposed protocol are deployed in an indoor environment to monitor the ambient temperature for fire detection. A comparison is made with the well-known cluster-based protocols developed for WSNs such as low-energy adaptive clustering hierarchy-centralized (LEACH-C) and a cluster-based protocol using Fuzzy C-Means (FCM) clustering algorithm. Experimental results demonstrate that the proposed protocol using HSA can be realized in centralized cluster-based WSNs for safety and surveillance applications in building environments. From the obtained experimental test results, it can be seen that the WSNs lifetime has been extended using the proposed HSA protocol in comparison with that of LEACH-C and FCM protocols.
