A Framework for Improving the Performance of MANET by Controlling Data Traffic using Proposed Mechanism

Abstract

A mobile ad-hoc network is a category of wireless network which does not depend on a predefined network structure or topology. Ad hoc networks require no centralized administration or fixed network infrastructure such as base stations or access points, and can be quickly and inexpensively set up as needed. Two mobile nodes can exchange data directly if they are in the defined range of each other. If not, nodes can communicate via a multi-hop route with the help of other mobile nodes. This paper proposed an approach to improve data transmission by reducing the data traffic and it also increase data availability in the mobile ad-hoc network. In the proposed approach, MANET is server client based network, means a mobile host acts as a server and fulfill the others node’s request. Each mobile node has a buffer for temporarily storing data fragment for a specific time, If a mobile node requests for a particular data fragment and the request is multi hoped, then first request is sent to its neighbor node, neighbor node first match requested data fragment with stored data, if it is matched the request will be responded by this neighbor otherwise request will be routed to mobile server. In this way the overhead of the server and server traffic will be reduced. The proposed method reduces time consumed by data fetching directly from server routing through multiple nodes and thus, it also enhances data availability.
