Multicast Routing with Quality of Service in Mobile Ad hoc Networks

Recently, multimedia and group-oriented computing become increasingly popular for the users of wireless mobile networks. Quality of service (QoS) issues has initiated to be studied in Mobile Ad hoc NETworks (MANETs) to support multimedia and real-time applications. MANETs can provide users with the mobility they demand, if efficient QoS multicasting strategies are to be developed. In this paper, we study the QoS requirements with multicast routing in ad hoc networks and propose a new cross-layer framework which provides QoS guarantees to multicast routing in MANETs. We propose a multicast routing protocol with mechanisms to ensure QoS guarantees to multicast session (call-admission, bandwidth reservation and delay constrain). The proposed routing protocol uses forward group to apply multicast routing with QoS from source(s) to a group of destinations.
