摘　　要：为解决基于BLE Mesh的健康监护系统中数据传输不稳定,部分节点死亡速度过快的问题,提出一种负载均衡多径路由算法。根据节点特性构建动态剩余能量计算模型和节点移动状态概率计算模型,在上述模型的基础上考虑链路质量情况引入负载均衡链路状态指标指导路由建立。仿真结果表明,该算法具有更高的投递率和更好的稳定性,能有效延长网络的生命周期,适合应用在对传输有效性要求较高的健康监护系统中。To solve the problems of unstable data transmission and excessive death rate of some nodes in the health monitoring system based on the BLE Mesh,a load-balancing multi-path routing algorithm was proposed.According to the characteristics of the nodes,the dynamic residual energy calculation model and node movement probability calculation model were designed.Based on the above model,the link quality was considered and the load-balancing link quality indicator was introduced to guide the route establishment.Simulation results show that the proposed algorithm has higher delivery rate and better stability,and can effectively extend the network life cycle,which is suitable for health monitoring system with higher transmission efficiency.
