Abstract

Routing in Optical Mesh Networks - A QoS Perspective

Highlights

  • The radio frequency part of the electromagnetic spectrum is classified into licensed and unlicensed bands, the existing unlicensed bands are already saturated the research is shifting towards using the optical part of the spectrum

  • We present the simulation results of the proposed routing protocol Quality of Service-Directional Routing Protocol (QDRP) and its comparison with Orthogonal Rendezvous Routing Protocol (ORRP) and Ad-Hoc on Demand Distance Vector (AODV), which is implemented for optical mesh network

  • The packet delivery percentage of AODV decreases with an increase in number of nodes but QDRP performs better compared to ORRP and AODV

Summary

Introduction

The radio frequency part of the electromagnetic spectrum is classified into licensed and unlicensed bands, the existing unlicensed bands are already saturated the research is shifting towards using the optical part of the spectrum. This technology is referred to as “optical communication without the fiber” and defined as “optical communication at the speed of light”[1].Environmental conditions such as fog, scattering, absorption affect FSO communication. For dense networks finding out the connectivity and best path in terms of QoS is a very cumbersome task. In this work a routing protocol with directional perspective is proposed for the optical mesh networks to satisfy QoS requirements. Through comparative evaluation we provide conclusions for the “metrics” packet delivery percentage, delay, number of hops and DOI:10.5121/ijasuc.2018.9201
