[ns] Regarding Timers in DSR

[Jian Li]

I think you miss the "start" command. In DSRAgent::command() in
dsragent.cc:

	  // cheap source of jitter
	  send_buf_timer.sched(BUFFER_CHECK
			       + BUFFER_CHECK * Random::uniform(1.0));
//start your timer here
          your_timer.handle((Event*) 0);
