A CROSS-LAYER DESIGN FOR AOMDV ROUTING PROTOCOL TO SATISFY QoS IN MOBILE AD HOC NETWORKS

Abstract

This paper proposes a cross-layer multi-path routing protocol, named Cross-layer Multi-path Routing Protocol (CMRP) for ad hoc networks. The protocol is developed based on AOMDV protocol and integration of two cross-layer designs. The Application-Routing cross-layer design aims to classify traffics of different application classes by Quality of Service (QoS) of the applications. The Routing-MAC cross-layer design aims to determine the appropriate routing metrics including link delay and packet loss ratio for each traffic class. The results of performance comparison between AOMDV protocol and CMRP protocol on the Network Simulator (NS2) with different traffic classes show that CMRP achieves better performance rather than AOMDV including end-to-end delay, throughput, overhead traffic and packet delivery ratio.
