A glance at quality of service models for mobile ad hoc networks

Mobile ad hoc networking is a challenging task due to the lack of resources reside in the network as well as the frequent changes in network topology. Although lots of research have been done on supporting QoS in the Internet and other networks, they are not suitable for mobile ad hoc networks and still QoS support for such networks remains an open problem. In this paper, we provide a brief overview of current QoS support for Internet and mobile ad hoc networks. We introduce a new definition of QoS in mobile ad hoc network, and base on that a cross-layer QoS model is suggested.
