A multimetric QoS routing protocol (MQOLSR) is proposed in this paper, which providing different QoS for different applications flow in an ad hoc network. The protocol, which integrates QoS measurement and packet forwarding, expands the topology discovery and routing computing mechanism of the OLSR protocol. It can provide different routing and forwarding service according to different application flow. The experimental results show that the MQOLSR protocol improves the network performance. Compared to the traditional OLSR protocol, the proposed routing protocol increases network throughput by 31.8% and reduces delay jitter when transmitting IPTV, while its routing overhead and routing discovery time are within an acceptable range.
