Hello all, I am implementing a distributed algorithm for sensor network, and I wrote an application and a transport protocol simil-UDP to send data. I have a strange problem in my simulation: at some point, one node stop to send packet, it is blocked and if I try to force the queue to send packet, I have a task overflow error from mac layer. I still do not know why this thing happen at some point, I am trying to do some debugging, maybe for some collision. Anyway I think this is not normal, because it should never happen that a node stop sending data (it continues to receive) at all forever, it should maybe reset itself if there is some problem. Maybe it is waiting for something? My application works very well over 802.11, so I think it should be the same with 802.15.4 (of course with a different output, number of packet etc). However it shouldn't stop!
What do you think? best regards Cesare Carretti
