Abstract

A Cross Layered framework is an important concept in today’s world given the abundant usage of both single-path and multi path wireless network architectures. One of the important design issues in the development of a robust framework such as this is the design of an Optimization Agent or an OA. In recent days of wireless and wired ad-hoc networks, cross-layer design was brought about a few years back to explore attached optimization at different layers. In order to describe solutions in cross-layered design, the Open System Intercommunications model was employed. However, it is clear that no voice and reference mechanism exists to aid optimization, which could effectively halt effective adaptability and deployment of cross-layered solutions. In this study, we suggest some hypotheses regarding how to model and create cross-layer solutions using the OSI layered method. We use the aforementioned method to analyse and simulate a particular type of cross-layered solution, namely energy-aware routing protocols. We use a layered approach to examine two proposals that are accessible in the literature. The applied strategy leads to the creation of an energy- aware, one-of-a-kind solution that outperforms prior versions and provides interesting and clear insights into the function that each layer plays in the overall optimization process. The network throughput, utilization, and reliability have all increased practically rapidly in the last few years. With the emergence of broadband wireless and wired cellular networks, as well as mobile adhoc networks (MANETs) and improved computational capacity, a new generation of apps, especially real-time multimedia applications, has emerged. Delivering real-time multimedia traffic across a sophisticated network like the Internet could be a particularly difficult undertaking, as these applications have stringent bandwidth and other quality-of-service (QoS) requirements.

Highlights

  • Cross-layer design and optimization may be a novel technique that has become commonplace in recent years and enhances network performance in both wired and wireless networks

  • The approach is to investigate the effects of the wireless channel on the physical layer performance of a small- scale wireless sensor network (WSN) in order to get insights that will be used to design and build the optimization agent within the proposed crosslayer framework

  • Due to the numerous benefits that cross-layer design could bring to the world, it is strongly advocated as a fresh new methodology for planning and performance optimization for wireless networks for future research

Summary

Introduction

Cross-layer design and optimization may be a novel technique that has become commonplace in recent years and enhances network performance in both wired and wireless networks. The primary concept behind cross-layer design is to optimise data control and exchange across two or more layers in order to achieve considerable performance gains by leveraging interactions between different protocol layers. Many of these difficult application cases impose significant network design constraints. The approach is to investigate the effects of the wireless channel on the physical layer performance of a small- scale wireless sensor network (WSN) in order to get insights that will be used to design and build the optimization agent within the proposed crosslayer framework Network nodes must be small, adaptable to a wide range of environments (e.g. body networks), and deployable in large numbers (i.e. dense networks); cheap, to ensure dense network deployment is costeffective; battery-powered, to ensure autonomy and freedom of movement while simultaneously forcing the energy consumption issue to become the most important concern in order to maximise efficiency.
