This paper proposes a group of picture (GOP)-aware multipath source routing protocol (GMSR) for real-time moving picture experts group (MPEG) video delivery in mobile ad hoc networks (MANETs).First,as existing multipath routing protocols usually produce large amount of route reply packets in a short period of time,which may cause traffic congestion,a cumulative route reply strategy (CRR) is employed in this work.Second,in order to enhance the reliability of the CRR,we investigate a selective route reply salvaging policy (SRRS) to protect an important route reply packet.Finally,we explore a novel cross-layer design framework according to the characteristics of MPEG video streams.On this basis,we introduce a GOP-aware flow control strategy (GFC) to coordinate video delivery,working together with the routing protocol.Our simulation results demonstrate that the GMSR achieves a significant improvement of the quality of real-time video streaming.
