摘要: 针对三维水声传感器网络中因节点或链路故障导致的路由性能低下问题,提出一种多径容错路由协议。该协议通过为每个节点设计一种称为后备箱的数据结构,并利用节点的路由表和后备箱构造主后备链路和辅后备链路,以便在节点或链路发生故障的情况下修复路由路径,确保数据的正常传输。仿真结果表明,多径容错路由协议可以减小节点或链路故障对数据传输率和网络吞吐量的影响。

Abstract: In order to solve the problem of low routing performance caused by sensor or link failures in Three Dimensional Underwater Acoustic Sensor Networks(3D UWASNs), this paper presents a Multi-path Fault-tolerant Routing(MFR) protocol. In MFR, each sensor has a data structure called backup bin, which is utilized to construct main backup links and auxiliary backup links together with routing table for repairing routing path and ensuring normal data delivery. Simulation results show that MFR protocol can reduce node failure or link failures’ impact to the data delivery ratio and network throughput.
