Wireless sensor networks (WSN) have found more and more applications in remote control and monitoring systems. Energy management in the network is crucial because all nodes in the WSN are energy constrained. Therefore, the design and implementation of WSN protocols that reduce energy depletion in the network is still an open scientific problem. In this paper, we propose a new clustering protocol that combines DEC (deterministic energy-efficient clustering) protocol with K-means clustering, called DEC-KM (deterministic energy-efficient clustering protocol with K-means). DEC is a very energy-efficient clustering protocol that outperforms its predecessors, such as LEACH and SEP. K-means ensures more effective clustering and shorter data transmission distances within the network. The shorter distances improve the network's lifetime and stability and reduce power consumption. Additional heuristic rules in DEC-KM ensure improved cluster head selection, taking into account node energy level and position and minimising the risk of premature cluster head exhaustion. The simulation results for the DEC-KM protocol using MATLAB show that cluster heads have shorter distances to nodes in cluster areas than for the original DEC protocol. The proposed protocol ensures reduced energy consumption, outperforms the standard DEC, and extends the stability period and lifetime of the network.
无线传感器网络（WSN）在远程控制和监测系统中的应用越来越广泛。网络中的能量管理至关重要，因为WSN中的所有节点都受能量限制。因此，设计和实现能减少网络能量消耗的WSN协议仍是一个有待解决的科学问题。在本文中，我们提出了一种新的聚类协议，它将DEC（确定性节能聚类）协议与K均值聚类相结合，称为DEC-KM（带K均值的确定性节能聚类协议）。DEC是一种非常节能的聚类协议，优于其前身，如LEACH和SEP。K均值可确保网络内更有效的聚类和更短的数据传输距离。更短的距离可提高网络的寿命和稳定性，并降低功耗。DEC-KM中的附加启发式规则可确保改进簇头选择，同时考虑节点能量水平和位置，并将簇头过早耗尽的风险降至最低。使用MATLAB对DEC-KM协议进行的仿真结果表明，与原始DEC协议相比，簇头到簇区域内节点的距离更短。所提出的协议可确保降低能耗，优于标准DEC，并延长网络的稳定期和寿命。
