QUIT: A cross-layer routing metric based on non-utilized outage capacity

Routing metric design is one of the key components of routing process in wireless ad hoc networks. Several routing metrics have been proposed over the past decade considering different criteria. This IEEE 802.11 standard compliant metric which is called QUIT considers four important factors of channel, namely, Quality, Utilization, Interference and Traffic load to determine the best route. We have derived and implemented this routing metric and compared its performance with best known routing metrics for different simulation scenarios. Simulation results show that this metric outperforms other metrics for different network traffic and node mobility scenarios.
