A NEW MULTI-PATH AODV ROUTING BASED ON DISTANCE OF
NODES FROM THE NETWORK CENTRE.


Introduction:

END-TO-END packet delay is one of the canonical metrics in Internet Protocol (IP) networks, and is important both from the network operator and application performance points of view. For example the quality of Voice Over IP is directly dependent on delay, and network providers may have Service Level Agreements (SLAs) specifying allowable values of delay statistics across the domains they control. An important component of end-to-end delay is that due to forwarding elements, the fundamental building block of which is the delay incurred when a packet passes through a single IP router. The motivation for the present work is a detailed knowledge and understanding of such “through-router” delays. We provide a comprehensive examination of these issues from three points of view. They are

the understanding of origins
measurement
and reporting

all grounded in a unique data set taken from a router in the access network of a Tier-1 provider. Although there have been many studies examining delay statistics and congestion measured at the edges of the network, very few have been able to report with any degree of authority on what actually occurs at switching elements. Here we propose a system by means of which the routing is done and thereby the congestion control is done.

Existing Scenario:

In END -To-END transmission packet delay is one of the major problems that we encounter all the time in a computer network. We can never predict the packet delay or predict that congestion can happen in a particular path. The only way is to identify the problem and then prevent it from ever happening again. The software's that are provided by CISCO are very costly and only large organizations will be able to afford them . Customization of the router also will be a greater problem for small organizations even if they are able to afford the cost. All of these obstacles could be overcome by our proposed system.

Proposed System:

In the proposed system we have designed a new multi-path AODV routing algorithm, the number of dropped packets will be decreased and indeed this will be happened with more balancing in the network. In this way the path congestion can be controlled and the efficiency of the network could be increased substantially. We could prevent the network from crashing and the data transaction will take place much more efficiently.

The modules that are linked with this proposed system are.

Scheduler:
The scheduler is used to perform the scheduling operations. Here the scheduler is doing the scheduling based on the priority that is assigned on the paths if they are free or congested.

Monitoring Entity:
The monitoring entity is used to monitor the path and thereby determine if the paths are congested or free.

User Management System:
It is used by the administrator for the purpose of monitoring the entire operation and to control it for better results.


Packet Capturing:

Here the packet analysis is done based on type and data. The packet analysis is done in order to determine the path of the packets.
