Research on Highly Dynamic Node BLE Mesh Routing Strategy based on Limited Flooding
摘要
Abstract
[Objective]Bluetooth Low Energy(BLE)is a low-power,low-cost wireless communication technology,and the de-velopment 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 envi-ronments 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 struc-ture,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 in-creased from 53.00%to 92.29%.And the average PDR of non-neighboring nodes in the limited flooding routing algorithm is im-proved from 78.73%to 86.97%as compared to the flooding routing algorithm.[Conclusion]The proposed limited flooding rout-ing 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.关键词
