摘要

自组织网络面临的主要问题之一是为多媒体应用提供特定的服务质量保证,这主要是由于无线电信号衰落和节点移动等因素造成的。由于网状网络是一种特殊类型的自组织网络,它继承了这些网络的问题。本文的主要目标是提出OLSR- md, OLSR(优化链路状态路由)的扩展,以提供基于链路延迟测量的服务质量。通过ns2(2.30版本)模拟,对帕拉联邦大学部署的网状网络中的OLSR- md进行了评估,结果表明该协议比模拟中研究的其他基于OLSR的替代方案性能更好。

Providing Quality of Service for Mesh Networks Using Link Delay Measurements
One of the main problems faced by ad hoc networks is providing specific quality of service guarantees for multimedia applications, mainly due to factors such as radio signal fading and node mobility. Since mesh networks are a special type of ad hoc network, they inherit these networks' problems. This paper's main goal is to present OLSR-MD, an extension to OLSR (optimized link state routing), to provide quality of service based on link delay measurements. An evaluation of OLSR-MD in a mesh network to be deployed at the Federal University of Para, by means of ns2 (version 2.30) simulations, showed that this protocol performed better than other OLSR based alternatives studied in the simulations.
