A framework for the admission control of QoS multicast traffic in mobile ad hoc networks

Recently, QoS issues have initiated to be studied in both wired and wireless networks, to support multimedia and real-time applications. In this paper, we propose a framework for the admission control of multimedia multicast traffic and for the system configuration in MANETs. We present a mechanism to ensure bandwidth guarantees to multicast sessions (Call-Admission Multicast Protocol for MANETs, M-CAMP). M-CAMP is scalable, operates on a per-call basis and supports the group membership dynamics. It adopts a measurement-based approach to evaluate the end-to-end bandwidth availability between the traffic source and the group of destinations. M-CAMP is independent of the underlying wireless technology and protocols, as far as a multicast routing service is available. It does not require any maintenance of status information in the mobile hosts.
