Objective: The main intent of this research is to improve the quality of service in Wireless Mesh Networks by reducing the number of hops and communication overhead generated in the network. Methods: In this manuscript, the Angle based Multicast Routing Algorithm (AMRA) is introduced for reducing communication overhead and thus improving performance in the wireless mesh networks. Every intermediate node towards the destination is selected based on the angle towards the forwarding nodes. The next intermediate node is selected in the forwarding direction, if the angle is within 60° of the current node. This method reduces the number of hops in transmitting data. Results: The Angle based Multicast Routing Algorithm (AMRA) show higher performance when compared to the existing CAMP method. If the number of nodes is 50, the packet delivery rate is comparatively better in AMRA and the throughput in AMRA is 70%. According to the comparison results, the proposed approach works better than the other existing schemes with high quality of service. Conclusion: The simulation results demonstrate that the Angle based Multicast Routing Algorithm (AMRA) has high quality of service compared to the existing CAMP.
