摘要
带AUV的静态网络是水声网络的一种典型应用形式。本文针对水声采集网络周期性采集数据的特点,设计了一种负载平衡的中心式水声网络路由协议。该协议在路由初始化阶段确保各节点能建立到达Sink节点的有效路由,而在数据传输阶段通过监听数据包信息进行路径优化,对节点的负载信息进行动态更新,从而使网络达到负载平衡。同时,针对移动节点路由易失效问题,给出了一种快速的路由接入方法。NS2仿真结果表明,本协议能有效平衡节点负载,大大提高移动节点的接入性能。
Static network with AUV is a typical structure of underwater acoustic network.Considering the characteristic of gathering data periodicity in underwater acoustic networks,a central routing protocol with load balance is proposed.It ensures that every common node has an effective route to Sink node in initialization phase.Then every node optimizes its mutt - path to Sink node through monitoring packets sent by neighbors and selects the path with lowest load in data gathering phase.In addition,a rapid way of rebuilding route is proposed for mobile node.Simulate results in NS2 show that this protocol can achieve load balance effectively and improve the receiving rate of mobile node at sink node.
