Abstract

A network is a group of two or more computer systems linked together. There are many types of computer networks which are categorized based on topology, protocol and architecture. A Mobile Ad hoc Network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. Ad hoc networks maintain an unfair behavior in flow control especially when considered in the case of IEEE 802.11 Mac layer. Introducing efficiency in 802.11 is not an easy task. It reduces the overall global throughput. The network is to be designed in such a way that it deals with the fairness and throughput by maximizing aggregate throughput. Such kind of network design can be efficiently implemented on an evolving simulation tool named OMNet++.

Highlights

  • A Mobile Ad hoc Network (MANET) is a selfconfiguring infrastructure less network of mobile devices connected by wireless

  • By controlling the scheduling of the packets flow from different hosts to the server efficiency can be maintained and there will be no decrease in the global throughput (Fig. 5)

  • This project briefly concludes how the efficiency in ad hoc networks is maintained without decrease in global throughput with the help of simulation tool OMNeT++

Summary

INTRODUCTION

A Mobile Ad hoc Network (MANET) is a selfconfiguring infrastructure less network of mobile devices connected by wireless. Packet losses due to errors in transmission: MANETs experience higher packet loss due to factors such as hidden terminals that results in collisions, wireless channel issues (high Bit Error Rate (BER)), interference and frequent breakage in paths caused by mobility of nodes, increased collisions due to the presence of hidden terminals and uni-directional links. It appears from the literature that designing a MAC protocol, fair and efficient in terms of global throughput that does not require any knowledge of the topology or specific information from other nodes than those provided by the MAC 802.11 protocol and the data traffic in the network is still a real challenge. In the OMNeT++ simulator, run-time efficiency is guaranteed by the fact that the textual model description is translated into C++ and used in its compiled form. When ACT or COL is equal to 1 for a node, this one considers that it shares the medium with one or more stations and reduces its MAC throughput by 2 by introducing a waiting time before
