An ad hoc network is comprised of mobile hosts without any wired infrastructure support. The primary concerns in ad hoc networks are bandwidth limitation and unpredictable dynamic topology. Therefore, efficient bandwidth utilization is crucial in routing protocols. The on-demand multicast routing protocol (ODMRP) was designed for multicast routing in ad hoc networks. However, ODMRP supports unicast routing too. It is very important to efficiently allocate and consume link bandwidth in this protocol, especially when many sessions are working concurrently. In this paper, we propose a new technique for supporting QoS routing in ODMRP using good estimation of available and required bandwidth. Simulation results show that using QoS routing for ODMRP in unicast mode improves network performance in presence of mobility, by searching for suitable paths
