Abstract: Multi-hop routing in mobile ad hoc networks (MANETs) requires good resource managing protocols. The efficient route from source to destination in the network is identified by determining the level of signal strength from intermediate hops. The link quality between the intermediate nodes is determined by calculating the signal strength level. The received signal strength is one method to estimate the medium characteristics and distance between the intermediate nodes which is one of the quality of service required by the network. The nodes with high signal strength and high bandwidth are identified as minimal delay nodes so as to determine the reliable path. The data is sent through minimal delay nodes in the shortest path from source to destination. The better link quality improves the performance metrics such as packet delivery ratio, throughput and simultaneously reduces the control message overheads, average and end-to-end delay compared to some of the existing routing protocols. The experimental study shows that the proposed routing protocol is 30% better in packet delivery ratio, throughput, reduced control message overheads, average and end-to-end delay than the existing stable and delay constrained routing protocol.
