Performance Analysis of Throughput and Queuing Delay for Multiple Optical Channels for Local Area Network

Abstract-The advances in Wavelength Division Multiplexing (WDM) technology have tremendously increased the bandwidth of a single fiber optic, for local and metropolitan area network (LAN and MAN). This paper presents and discusses a new network environment that is multiple optical channel, which coupled Ethernet with WDM to decrease the average queuing delay and increases the normalized throughput. The performances of three channels are evaluated with different network parameters using discrete event simulator called OMNeT++. In this paper it has been proved that RS BEB algorithms show the best throughput for three data rates. Moreover, in average queuing delay and RS BEB shows the lowest delay despite the others algorithms. It has been observed from this work that an increase in the number of nodes, the percentage of normalized throughput decreasing is less than 20% for every additional node in the network

A Network Coding-Aware Directional Broadcast Routing Scheme for VANET

Recent technological advancements in wireless communications are fundamentally changing the manner by which devices communicates with one another. Modern wireless devices build networks on their own and aid each other in passing information to any device in the network. The aim of this research is to design and develop a robust routing protocol using network coding technique for Vehicular ad hoc networks (VANET). The purpose of the protocol is to disseminate vehicular traffic to the vehicles approaching the problem area, rather than those leaving the problem area. The designed protocol during the research will be more robust, reliable, and efficient with topology change. In this research, network coding and geographical routing models will be used to develop network coding based VANET routing protocol for alerting vehicles approaching the accident area and emergency message dissemination. The network coding model assumed will serve to increase throughput, in this sense reducing packet loss which will provide a robust broadcast routing protocol
