In this paper, we propose a delay-aware multipath source routing (DMSR) protocol to provide QoS support for real-time multimedia applications in wireless ad hoc networks. Based on local information, node delay is calculated as metric for route path selection in the DMSR protocol. The metric takes into account the number of the neighbor nodes of the forwarding nodes, the channel busy time and the number of packets in the send buffer. Simulation analyses and results show that the DMSR protocol can reduce the average end-to-end delay and meet the demands of real time multimedia services compared to the dynamic source routing (DSR) protocol and the improved DSR (i-DSR) protocol.
