QoS Based Performance Evaluation for MANETs

QoS support in MANETs is challenging because of unfavourable conditions such as a dynamic topology, limited bandwidth and energy constraints. In the past decade, significant effort has been devoted to QoS routing design which fails to obtain a one-for-all solution for MANETs. This reason, it is believed, is the application dependent nature of routing protocols. Moreover, few researchers consider the relative importance of QoS metrics. Last but not the least, performance metrics are compared independently without any conclusion indicating the optimal protocol in a given scenario. In this paper, a QoS based performance evaluation with analytic hierarch process (AHP) is proposed and the alternative protocols are ranked according to the relative importance of QoS metrics.
