摘要/Abstract

Abstract:

Quality of service (QoS) routing and multicasting protocols in ad hoc networks are face with the challenge

of delivering data to destinations through multihop routes in the presence of node movements and topology changes.

The multicast routing problem with multiple QoS constraints is discussed, which may deal with the delay, bandwidth and cost metrics, and describes a network model for researching the ad hoc networks QoS multicast routing

problem. It presents a distributed QoS multicast routing protocol (DQMRP). The proof of correctness and complexity analysis of the DQMRP are also givea Simulation results show that the multicast tree optimized by DQM-

RP is better than other protocols and is fitter for the network situations with frequently changed status and the real

time multimedia applicatioa It is an available approach to multicast routing decision with multiple QoS constraints.
