Sensor nodes are the building blocks of wireless sensor networks (WSNs), which may gather, analyze, and transmit various types of information to a certain destination. Data collection and transmission to the destination are the main responsibilities of sensor nodes at specified time intervals. However, one of the biggest issues with WSNs is the creation of energy-efficient wireless network algorithms. In this paper, a multi-hop multi-antenna power beacon path selection (MMPS) protocol is proposed. The proposed approach consists of a source, a destination, relays, power beacons generating radio frequency (RF) signals for energy harvesting, and eavesdroppers. We used physical layer security associated with energy harvesting to protect data from eavesdroppers without requiring higher layer data encryption and enhance the energy consumption of wireless networks. The signal's broadcast strength must be high enough to allow for energy harvesting while being low enough to prevent eavesdropping. The process continues until the data reaches the destination. Comparing the performance of MMPS with those of conventional methods, MMPS enhanced the wireless network outage probability (OP) up to 99.7%, life time, energy consumption, protection from eavesdroppers, and more resistant to hardware impairments which increased the immunity up to 95%.
传感器节点是无线传感器网络(WSN)的组成部分,它可以收集、分析和传输各种类型的信息到某个目的地。传感器节点的主要职责是在指定的时间间隔内进行数据收集和传输到目的地。然而,WSN 面临的最大问题之一是创建节能的无线网络算法。在本文中,提出了一种多跳多天线功率信标路径选择(MMPS)协议。该方法由源节点、目的节点、中继节点、功率信标组成,功率信标产生射频(RF)信号用于能量收集,同时还存在窃听者。我们使用与能量收集相关的物理层安全来保护数据免受窃听者的攻击,而无需更高层的数据加密,并提高无线网络的能量消耗。信号的广播强度必须足够高,以允许能量收集,同时又足够低,以防止窃听。该过程一直持续到数据到达目的地。将 MMPS 的性能与传统方法进行比较,MMPS 将无线网络的中断概率(OP)提高了 99.7%,同时延长了网络的寿命、降低了能量消耗、提高了对窃听者的保护能力,并且增强了对硬件损伤的免疫力,提高了 95%。
