摘要:

为解决移动Ad Hoc网络中QoS路径公共链路造成的带宽预留冲突,提出了一种分散链路状态多路QoS路由选择,它动态地收集源地址到目的地的分散链路状态信息,找出节点不相交的路径,根据LBHBF策略选择合适路径使延迟和总带宽满足QoS要求,并预留相应路径带宽。模拟结果显示,该方法提高了调用成功率,减少了网络费用。

Abstract: In order to solve the bandwidth reservation conflict caused by the common links of QoS routes in mobile ad hoc networks, this paper proposes a disperse link-state multi-path QoS routing. It dynamically collects disperse link-state information from source to destination, and finds node-disjoint paths. According to the LBHBF strategy, it chooses proper paths whose delay and aggregate bandwidth to meet the QoS requirement, and reserves the bandwidth of corresponding paths. Simulation results show this scheme increases the call success rate and decreases the network cost.
