[ns] Using Directed Diffusion in ns-2.29

[Raghu-kisore Neelisetti]

Hello Every one,
 The class DiffusionRouting has a member variable timers_manager (of
type TimerManager). If i were to activate the flag NS_DIFFUSION then i
see that the function "timers_manager_->executeAllExpiredTimers(); "
never gets called (as it is always gets only called from the #ifndef
NS_DIFFUSION). If this is the case then i wonder how any of the Events
in the event queue will  ever get executed.
Please let me know if this is some kind of bug. Iam using ns-2.29.
same is the case with the implementation of  "class DiffusionCoreAgent".

Thanks
Raghu.
