delay AODV start

[Francisco Eduardo Balart Sanchez]

Good day:

I'm implementing a cluster-based algorithm as MAC, to make experimentations i would like to

be able to delay the start of the AODV protocol.

• This thread talk about it but shows not much info
• https://groups.google.com/d/topic/ns-3-users/GeZJ8IbXw0c/discussion
  

There are two parts of the routing protocol i think should have such delay (i think)

1. The  RoutingProtocol::Start Function

  358 void

 359 RoutingProtocol::Start ()

 360 {

 361   NS_LOG_FUNCTION (this);
  //Should if put a sleep here or schedule to do nothing here?
  //Or propagate such delay on all timers (i don't think this woudl be good idea)

  362   if (m_enableHello)

 363     {

 364       m_nb.ScheduleTimer ();

 365     }

 366   m_rreqRateLimitTimer.SetFunction (&RoutingProtocol::RreqRateLimitTimerExpire,

 367                                     this);

 368   m_rreqRateLimitTimer.Schedule (Seconds (1));

 369

  370   m_rerrRateLimitTimer.SetFunction (&RoutingProtocol::RerrRateLimitTimerExpire,

 371                                     this);

 372   m_rerrRateLimitTimer.Schedule (Seconds (1));

 373

  374 }

2. The DoInitialize

 2113 void

2114 RoutingProtocol::DoInitialize (void)

2115 {

2116   NS_LOG_FUNCTION (this);

2117   uint32_t startTime;

2118   if (m_enableHello)

2119     {

2120       m_htimer.SetFunction (&RoutingProtocol::HelloTimerExpire, this);

2121       startTime = m_uniformRandomVariable->GetInteger (0, 100);
      // The startTime is for the hello world

2122       NS_LOG_DEBUG ("Starting at time " << startTime << "ms");

2123       m_htimer.Schedule (MilliSeconds (startTime));

2124     }

2125   Ipv4RoutingProtocol::DoInitialize ();

2126 }

2127

Thanks in advance and best regards

Is the ns3::SystemConditionPrivate::TimedWait  the appropriate method?

[Francisco Eduardo Balart Sanchez]

I was also thinking on a "wrapper" of Start or DoInitialize as shown below

aodv::Start()
{
    //Port the code from here to StartTwo
    Schedule(Delay, StartTwo);
}

Not sure if this or the TimedWait would be better option

thanks in advance and best regards
