Study of QoS in Cross Layer Based Ad Hoc Networks

The increasing popularity of the multimedia applications in mobile ad hoc networks (MANETs) has led to research on QoS support for these applications. However, this is difficult in such networks because of factors such as shared and variable wireless bandwidth, limited power supply and possible mobility of the nodes. Much has been done to the quality of service problem of ad hoc networks, and many QoS provisioning schemes have been presented. This paper addresses some of the achievement of the QoS issues for cross layer based ad hoc networks which have recently started to receive increasing attention in the literature. We present the basic concepts and discuss some of the recent results, then conclude with some observations on the open areas for further investigation.
