This article presents a new quality of service (QoS) routing protocol for delay sensitive traffic in Mobile Ad Hoc Networks (MANETs). It takes advantage of the different communication capability to design more efficient QoS routing protocol. In this protocol, a combined weight value is estimated based on the data rate, queuing delay, link quality, residual energy and MAC overhead for each node. Among all the nodes in the network, there are some strong nodes with least combined weight value. These nodes serve as the backbone for the routing in mobile ad hoc networks, and other nodes are general nodes with lesser capabilities. Simulation results prove that by reducing the packet drop, energy and delay the proposed routing protocol achieves high throughput and packet delivery ratio.
