Abstract
The optimized link state routing (OLSR) protocol is a proactive link-state protocol for ad-hoc networks. It uses an optimization called multi-point relays (MPRs) to provide an efficient broadcast structure and to reduce the number of link advertisements. Various propositions have been made to enhance the quality of service (QoS) of the routes that OLSR provides, selecting routes according to metrics such as their expected loss rate or throughput. This paper analyzes the existing propositions and finds them lacking. By building upon OLSR's link announcement mechanism, these solutions permit the advertisement of links with non desirable properties and can only support one class of service. We propose ways to improve one of the propositions, QOLSR. Our QOLSR+ uses MPRs only to create a reliable broadcast structure and employs modified link announcements to increase the number of advertised links
OLSR (optimized link state routing)协议是面向ad-hoc网络的一种主动链路状态协议。它使用一种称为多点中继(MPRs)的优化来提供有效的广播结构并减少链路广告的数量。为了提高OLSR提供的路由的服务质量(QoS)，根据预期损失率或吞吐量等指标选择路由，已经提出了各种建议。本文分析了现有的命题，发现其不足之处。通过构建OLSR的链接公告机制，这些解决方案允许发布不需要的属性的链接，并且只能支持一类服务。我们提出了改进其中一个命题——QOLSR的方法。我们的QOLSR+仅使用mpr来创建可靠的广播结构，并使用修改的链路公告来增加发布的链路数量
