[Tinyos-help] Reducing Multiple Timers ??

[Mahesh Satharla]

I am a Research Assistant at WiSe MANet Labs in University of Memphis.

I am currently working on one project, for which it requires a Sensor
mote(Tmote Invent) should monitor all of its neighbors.So i am using
Multiple Timers to do so.For Monitoring motes, If a Mote A have 5 neighbors
it should maintain 5 timers and if any thing goes wrong or say Timer expired
for particular Mote B and didn't received any message from that   Mote B,
then Mote A should send Message to Base Station regarding Mote B.

If a mote have 10 or 20 Neighbors, maintaining 20 timers for monitoring is
not feasible i guess.

So, is any way i can reduce Multiple Timers ??
Did any work has been done in sensor networks for reducing Multiple Timers
or Monitoring Neighbor Motes???

Can anyone Help me out.??

Thanks and Regards,
Mahesh Satharla.
