IXLDA: Integrated Cross-Layer Design Approach for Performance Optimization in MANET

Authors : P. Thangavel and T. Ravichandran

Abstract: In this study, we present an Integrated Cross-layer Design Approach (IXLDA) to enable smart interactions between Transport, Network, Medium Access Control and Physical layers. This approach jointly enhances the data rate adaptation, link quality prediction, routing mechanism and congestion control to realize significant gains in the overall performance of the network. We implant our IXLDA in AODV routing protocol and the new cross-layer AODV (XL-AODV) protocol is simulated using Network Simulator (NS-2). The performance of XL-AODV is compared with non-optimized traditional routing protocols based on three well-known performance metrics. The mean packet delay of the proposed algorithm is 21.86% lesser than basic AODV and 8.10% lesser than M-AODV. Indeed, the average throughput improvement of XL-AODV is about 26.67% higher than basic AODV and 17.70% higher than M-AODV. The substantial improvement in the Packet Delivery Ratio (PDR) achieved by XL-AODV is 8.80% compared to AODV and about 3.32% compared to M-AODV.
