The infrastructure-less and dynamic nature of mobile ad hoc networks demands a new set of networking strategies to improve the performance of quality of service (QoS). Providing QoS is a major issue in Manets. The traditional layered approach does not fit well for ad hoc networks due to high mobility and dynamic topology. This paper implements the cross layer design approach on DYMO routing protocol in Manets by using Qualnet simulator in both traditional layered approach and proposed cross layer approach. The proposed methodology uses four QoS metrics: throughput, end-to-end delay, packet delivery ratio and jitter. The experimental result reveals that QoS performance is enhanced in CLD approach for DYMO. The throughput in traditional layered approach for DYMO is 1961 b/s, whereas in the CLD approach it is 2986 b/s. Finally this paper concludes that cross layer approach significantly improves the QoS performance when compared with layered approach.

“…Pro-active routing is also called Table driven routing where as re-active routing is called On-demand and dynamic routing. Reactive routing protocols are popular in MANETs because they are more scalable and less overhead on the network [2][3][4]. AODV, DSR and DYMO are popular reactive routing protocols.…”

“…There are a plethora of MAC protocols proposed in the literature. Prior studies have investigated previous MAC layers 4 impact on some routing protocols, such as 802.11 and CSMA on AODV and LAR, but not TSCH. Therefore, in this paper, we investigate the use of TSCH with AODV and compared it with traditional CSMA.…”

AODV (Ad hoc On‐Demand Distance Vector) is a well‐known routing protocol for wireless networks. Recently, Time Slotted Channel Hopping (TSCH) was proposed as a MAC layer protocol, specified in the IEEE 802.15.4e standard. As MAC layer protocols can impact the performance of protocols in the layers above, we examine the performance of AODV over TSCH and compare it with CSMA. We investigate using different metrics, such as latency, packet delivery rate, and energy consumption. We implemented AODV, as defined by the RFC 3561, using the embedded systems operational system Contiki‐NG, a well established platform for Low power and Lossy Networks (LLNs), and the Internet of things (IoT). Our results, running on the Cooja platform, show that TSCH can greatly improve the performance of AODV, achieving a packet delivery rate of almost 100%. Moreover, our results also show that TSCH consumes less energy than CSMA.

“…They concluded that routing protocols shows better performance in Random way point mobility model [1]. Muhammad Ibrahim et al [2] presented certain QoS models that provide architecture for providing QoS to the mobile nodes in the MANETs. Hanzo, L. and Tafazolli et al [3] presented problems that may occur in providing QoS to Mobile nodes in Mobile Ad-hoc networks and solution for managing those problems, like dynamic topologies, that change continuously and unpredictable at any time.…”

Abstract. Wireless and mobile communication networks are becoming more and more fashionable in today's mobile world. In wireless communications, Mobile Ad hoc Networks play crucial role. Ad hoc network is an infrastructureless and self -organized collection of autonomous nodes. In mobile ad hoc network, routing is one of the thrust areas. There are no committed routers in MANETs; every network node should contribute to routing. Simulation tools are used to analyze the performance of routing protocols in MANETs. Propagation models show strong impact on the performance of routing protocols during simulations. This paper investigates the impact of familiar propagation models Two-ray and Shadowing on the performance of AODV and DSR routing protocols using NS-2. Experimental results found that both AODV and DSR show better throughput in two-ray ground model.
