Impact of network conditions on QoS routing algorithms
B. Peng, Andrew H. Kemp, Said Boussakta · 2006
QoS Routing has been studied to provide evidence that it can increase network utilization compared to routing that is insensitive to QoS traffic requirements. This paper aims to discover in detail the relationship between the routing algorithms and network conditions (traffic load and the scale of the network topology) both in fixed and random source-destination pairs in different topologies. We demonstrate that network scale affects the performance, and give evaluation of different locations of source-destination pairs. We also point out the importance of using length of route as a metric to evaluate algorithms. This has seldom been used in previous simulation studies.
