multipath aodv coding in ns2

Abstract

Video transmission is nowa days become a well established facility and has many applications.Video transmission over wireless network requires page link reliability. videos are having more data to be transmitted during communication. Traditional routing protocol suffers from limitation like page link failure. It motivates to Multi-Path routing scheme that provides reliability. There is also need to make modification during path selection in multipath protocol. It ispossible to enhance network lifetime wi ....etc

how to set sleep and wakeup for nodes in ns2 in aodv

public:
AODV();
void CLUSTERING();
..
AODV.cc :
void AODV::CLUSTERING(){
if(current_){
while(numberofNodes){
// Selecting clusters
}
}
}
Now we know how the mechanism of ns2 works.so let's get started with sleep nodes.
First of all there is 4 functions in ns2 for turning a node to 'off', 'on', 'sleep', 'idle'. The difference between these are not so big.
As you know the 'off' function turns a node to off but it still broadcasts something based on your protocol.
$ns_ at 7.0 $ ....etc

its just been a while since i used ns2.
i am trying to play around with the AODV protocol in ns2.
there,inside ns2/aodv directory,i find files such as aodv.cc,aodv.h,aodv_logs.cc etc.. please expalin me in detail what are these files and how they work together.
if you have the page link to answer my query,i would be more than happy
thanks in advance. ....etc

ABSTRACT

At the same time as the emergence of multimedia in mobile Ad hoc networks, research for the introduction of the quality of service (QoS) has received much attention. However, when designing a QoS solution, the estimation of the available resources still represents one of the main issues. This paper suggests an approach to estimate available resources on a node. This approach is based on the estimation of the busy ratio of the shared canal. We consider in our estimation the several constraints related to the Ad hoc transmission mode su ....etc
