摘要：As a result of the rising popularity and necessity of real-time multimedia applications, Quality of Service (QoS)monitoring needs more attention in wireless networks. Due to infrastructureless and mobile nature of wireless mobilead hoc networks (MANETs), QoS monitoring is a challenging task. This paper extends our previously published workand provides a framework for a robust and a multi-metric QoS monitoring infrastructure (MMQoSMI) for MANETs.Three QoS metrics (delay, jitter, and packet loss) are considered by the proposed QoS monitoring framework. TheMMQoSMI nodes are mainly selected based on individual node stability and available bandwidth for each node.Then, these nodes are implicitly connected using link bandwidth and delay as QoS metrics. For an MMQoSMInode to measure the QoS metrics of its directly connected links, it relies on the Minkowski distance approach.This approach measures the selected QoS metrics and then enters them to the distance assessment system whileconsidering customer’s QoS requirements of each multimedia application. As a result, MMQoSMI nodes combinethe selected QoS metrics and produce an output that represents the instantaneous QoS. Every node in the MANETassesses the available QoS and then forwards it to its cluster-head node to be used for network monitoring and otherpurposes
