支持移动自组网的柔性链路状态路由协议

在移动自组网(MANET)中，服务质量(QoS)路由的目标是要确定一种具有足够可用移动节点的有效路由路径来满足源点的需求，而且被选择的多点中继(MPR)节点是处在通过路由协议计算产生的最优路由路径上。为了能在较短时间内稳定地寻找到从源点到终点带有最大带宽和最小时延的最优QoS路由路径，提出一种新的柔性链路状态QoS路由协议FLSQR。该协议使用了一种新的链路状态方法——每个节点缓存中存储一张效用决策表(EDT)用作路由计算。FLSQR根据EDT中的效用距离(ED)使用MPR1和MPR2选项来选择最优和次优路由路径，进而通过提出的度量模型选择最优带宽和时延的路径。实验结果显示，FLSQR协议在MANET中的最优路由路径发现方面比OLSR和QOLSR-MPR协议性能更好。

Flexible link-state routing protocol for mobile Ad Hoc networks

The aim of the Quality of Service(QoS) routing in Mobile Ad Hoc NETwork(MANET) is to determine an efficient route with enough available mobile nodes to satisfy a request of a source node,and the selected nodes of Multi-Point Relay(MPR) are on the optimal route that needs evaluating by the routing protocol.In order to steadily look for the optimal QoS routing path with maximum bandwidth and minimum delay from a source node to a destination node with shorter time,a new flexible link-state QoS routing protocol called FLSQR was proposed,which used a new link-state method in which each node’ cache stores an Effective Decision Table(EDT) for routing calculation.The FLSQR used the MPR1 and MPR2 selection according to the Effective Distance(ED) in EDT to select the optimal and suboptimal routing paths,and further chose the path of optimal bandwidth and delay by presented metric model.The experimental results show that the proposed FLSQR protocol can acquire better improvement in finding an optimal routing path in MANET than the OLSR and QOLSR-MPR protocol.
