摘　　要：在以家庭灯联网为背景的蓝牙Mesh组网的多对多路由通信机制中,针对灯联网的低延时性和高可靠性的要求,设计一种基于AODV路由协议的改进路由算法。算法在路由链路质量判断中考虑了时延、跳数和级联数据包接受率(PRR),针对链路可靠性的评估提出了新的方法来寻找最优路由和次优路由。在路由维护过程中,将次优路由作为备份路由与最优路由协同通信。仿真结果表明,该算法有效提高了路由的发包可靠性和时延,进而使得灯联网网络的路由质量得到了明显改善。The requirement for low delay and high reliability is addressed by designing an enhanced routing algorithm based on the Ad Hoc On-Demand Distance Vector(AODV)routing protocol in the many-to-many-route communication mechanism of Bluetooth Mesh networking,specifically tailored for home light networking.This algorithm takes into consideration factors such as delay,hop count,and cascade packet reception rate(PRR)to assess link quality,and proposes a novel approach to evaluate link reliability in order to identify optimal and sub-optimal routes.During route maintenance,the sub-optimal route serves as a backup for communication with the optimal route.Simulation results demonstrate that this proposed algorithm significantly enhances both routing reliability and delay performance,leading to noticeable improvements in lamp network quality.
