[Tinyos-help] multihop routing for tinyos2.x and mica2 motes

[Faisal Aslam]

I will say use tinyOS implementation of Dymo routing 
(http://docs.tinyos.net/index.php/Tymo). They called it Tymo.
Dymo is modified form of AODV. They remove the routes after sometimes if 
it is not used and there is some timeout for each route maintained.
However, you could modify it to fulfill your needs (may be increase the 
timeout or remove it).
They have a variable DYMO_ROUTE_TIMEOUT for the timeout. See their code....

best regards,
Faisal Aslam
