Design of a Quality of Service-Based Multicast Routing Protocol for Mobile Ad Hoc Networks
Authors propose a Quality-of-Service (QoS)-based multicast routing protocol, referred to as QoS-MR, for mobile ad hoc networks (MANETs). QoS-MR is a receiver-initiated mesh-based multicast routing protocol and can work for both combinatorially stable and unstable networks. Authors explain in detail the procedures for mesh construction (initiation by the source, propagation of the control packets by the intermediate nodes and route selection by the receiver) and mesh maintenance/repair. Authors take into account QoS metrics such as bandwidth, end-to-end delay and link lifetime. The source specifies the desired QoS characteristics of the application in the control messages broadcast for mesh formation and the intermediate nodes forward the control messages only if they could satisfy the QoS demands and reserve the resources requested by the application.
