Improvement in Quality of Service (QoS) of wireless networks has always been a study subject for wireless network designers worldwide. Optimization of end to end communication delay, reduction in energy consumption, improvement in network throughput and reduction in end to end communication delay jitter are some of the parameter optimizations which are used to improve the QoS of the wireless networks. In this paper, we propose a QoS aware routing protocol which uses a combination of delay & energy aware routing with data aggregation & multichannel communication in order to reduce the energy consumption, reduce the end to end delay and improve the network throughput. The simulation results show that there is a more than 20% improvement in network communication speed, and atleast 15% improvement in the network lifetime after using the proposed QoS aware routing protocol.
