移动的ad hoc网络具有非常吸引人的内在品质。但是，只有当它们能够支持具有QoS要求的应用程序时，才会采用它们。它们必须提供路由，该路由提供流所请求的QoS。OLSR路由协议可以为此目的进行扩展。OLSR依赖于多点中继（MPR）选择，对路由协议的性能有重要影响。实际上，由OLSR协议生成的开销以及更具体地洪泛效率取决于MPR选择。此外，MPR被用作路由中的中间节点。本报告中对MPR选择的分析给出了定量结果，并考虑了QoS支持。在大型密集网络上的仿真表明，我们的分析是高度准确的。
Mobile ad hoc networks have very attractive intrinsic qualities. However they will be adopted only if they are able to support applications with QoS requirements. They must provide a route providing the QoS requested by a flow. The OLSR routing protocol can be extended for that purpose. OLSR relies on multipoint relay (MPR) selection that has an important effect on the routing protocol's performances. Indeed, the overhead generated by the OLSR protocol and more particularly the flooding efficiency depend on MPR selection. Moreover, MPRs are used as intermediate nodes in the routes. The analysis of MPR selection presented in this report gives quantitative results and also takes into consideration QoS support. Simulations on large and dense networks show that our analysis is highly accurate.
