Summary The direction and velocity of a node are the most important parameters to create a valuable path in ad hoc networks. A valuable path is one that has a longer life time and more durability than others. As we know, the durability of a path is under the influence of the nodes' velocity. This paper proposes an algorithm to provide QoS in ad hoc networks. The proposed algorithm entitled Modified Light Weight distributed QoS Algorithm, considering the direction and relative velocity of the nodes and predicting the value of link durability, chooses a path with longer duration time, minimizes the link breaks, and improves QoSs. We implemented it in a simulation environment by using the Network Simulator Version 2 software and evaluated the effectiveness of it in packet delivery ratio, packet delivery latency, average end‐to‐end delay, routing overhead, and dropped packets. The simulation results demonstrate that Modified Light Weight distributed QoS Algorithm improves the QoS parameters in ad hoc networks.
