摘　　要：【目的】低功耗蓝牙(BLE)是一种低能耗和低成本的无线通信技术,低功耗蓝牙自组网(BLE Mesh)的出现则进一步提升了网络的可扩展性和通信范围。Fruitymesh是目前唯一开源的基于路由的BLE Mesh组网策略。但在高动态节点环境下使用Fruitymesh会出现因节点频繁进出而导致的树状拓扑网络传输链路中断以及数据传输成功率明显降低的问题。为了解决该问题,文章利用Fruitymesh组网思想提出了一种适用于高动态节点的有限泛洪路由策略。【方法】通过修改聚类评分机制,将网络拓扑由树状拓扑改进为部分网状拓扑,增强了网络拓扑的整体可靠性。同时,添加路由选择机制设计有限泛洪路由策略。【结果】仿真验证表明,相较于Fruitymesh,有限泛洪路由策略的网络拓扑抗毁性提升了71.4%,在定点打击中,网络整体数据包投递率(PDR)从15.00%提升至85.67%;在随机打击中,网络整体PDR从53.00%提升至92.29%。而相较于泛洪路由算法,有限泛洪路由算法中非邻居节点的平均PDR从78.73%提升至86.97%。【结论】文章所提有限泛洪路由策略能够有效提高网络拓扑的抗毁性、路由传输可靠性以及高动态节点环境下网络通信的成功率。【Objective】Bluetooth Low Energy(BLE)is a low-power,low-cost wireless communication technology,and the development of BLE Mesh further enhances the network scalability and communication range.Fruitymesh stands as the only open-source routing-based BLE Mesh networking strategy at present.However,using Fruitymesh in highly dynamic node environments leads to issues such as interruptions in tree-shaped topology network transmission links due to frequent node entries and exits,resulting lower data transmission success rates.To address this problem,this paper utilizes the networking principles of Fruitymesh and proposes a limited flooding-based routing strategy suitable for highly dynamic node scenarios.【Methods】By modifying the clustering scoring mechanism,the network topology is refined from a tree-shaped structure to a partial mesh structure,enhancing the overall reliability of the network topology.Simultaneously,a route selection mechanism is introduced,and a limited flooding routing strategy is designed.【Results】Through simulation verification,compared to Fruitymesh,the limited flooding routing strategy demonstrates a 71.4%improvement in network topology robustness.In fixed-point attacks,the overall network Packet Delivery Rate(PDR)is increased from 15.00%to 85.67%.In random attacks,the overall network PDR is increased from 53.00%to 92.29%.And the average PDR of non-neighboring nodes in the limited flooding routing algorithm is improved from 78.73%to 86.97%as compared to the flooding routing algorithm.【Conclusion】The proposed limited flooding routing strategy in this paper effectively enhances the network topology robustness,route transmission reliability,and the success rate of network communication in highly dynamic node environments.
