Load Balancing Relay Selection Algorithm Based On Physical Layer Security

针对多源多中继系统中存在的恶意窃听问题,提出了基于物理层安全的负载均衡中继选择算法。该算法通过联合相似度明确社交属性,确定潜在拒绝服务中继。构建了低联合相似度下的多维决策流程,进而避免了网络中能量负载和数据负载在单一节点的无限制消耗。解决了通信质量约束的节点资源消耗的不公平性和网络寿命低等问题。仿真结果表明:所提方案与传统方案相比,网络寿命延长了179%,总吞吐量提升了150%。

Aiming at the problem of malicious eavesdropping in multi-source and multi-relay systems,a load balancing relay selection algorithm based on physical layer security was proposed.This algorithm clarified social characteristic through joint similarity,determined potential denial of service relays,and builded a multidimensional decision-making process under low joint similarity.The unlimited consumption of energy load and data load was avoided in a single node in the network.The problems of unfairness of node resource consumption and low network lifetime was solved due to communication quality constraints.The simulation results show that the proposed scheme can prolong the network life by 179%and the total throughput is increased by 150%compared with the traditional scheme.
