A multiple path-metrics based multi-path routing protocol for providing differentiated QoS to various data traffic

Abstract

In this paper, we propose a novel multiple path-metrics based multi-path (MPMP) routing protocol, which can find the most suitable route that satisfies the requirements of various data traffic in mobile ad hoc networks (MANETs). In order to provide differentiated QoS to various traffic, we propose a weighted cost function based on multiple path metrics, and D-ETX (Data-driven ETX) and available bandwidth estimation methods. To our best knowledge, this work is the first attempt to consider the multiple metrics-based multi-path selections for providing differentiated QoS to various traffic in MANETs. Simulation results demonstrate that the proposed protocol can achieve a significant improvement in terms of packet delivery ratio and end-to-end delay over existing protocols.
