Abstract

QoS is the collective effect of service performance which determines the degree of satisfaction of a service. Since it is the collective effect of a service, it must have significant impact on the performance of routing protocols of any network. In MANET where the network has no fixed infrastructure and eventually the topology is continuously changing, QoS is a more challenging issue. However, the ability of a MANET to provide adequate quality of service (QoS) is limited by the ability of the underlying routing protocol and MANETpsilas QoS requirements can be quantified in terms of Packet Delivery Fraction, Average end-to-end delay of data packets and Normalized Routing Load. So, this paper, for the first time, presents the effect of data send rate, node velocity and transmission range on QoS parameters of the two contrasting MANET routing protocols OLSR and DYMO. These two protocols are simulated and compared with NS-2 under Gauss Markov mobility model. The simulation results show significant QoS performance differences.

研究了数据发送速率、节点速度和传输范围对OLSR和DYMO MANET路由协议QoS参数的影响。

QoS是服务性能的集体效应，它决定了服务的满意程度。由于它是服务的集体效应，因此它必然对任何网络的路由协议的性能产生重大影响。在MANET中，网络没有固定的基础设施，并且最终拓扑结构是不断变化的，QoS是一个更具挑战性的问题。然而，MANET提供足够的服务质量(QoS)的能力受到底层路由协议和MANET的能力的限制，QoS需求可以通过分组交付分数、数据包的平均端到端延迟和规范化路由负载来量化。因此，本文首次研究了数据发送速率、节点速度和传输范围对两种对比MANET路由协议OLSR和DYMO的QoS参数的影响。在高斯马尔可夫迁移模型下对这两种协议进行了仿真，并与NS-2进行了比较。仿真结果显示了显著的QoS性能差异。
