Hi,
I am trying to implement a true mesh routing. I have
finished implementing an elementary routing layer
above the ActiveMessage layer. But I am facing a lot
of packet drops. This I guess is due to collision. I
added the packetacknowledgements to solve the problem
but still the case is same. I think MAC layer should
take care of link level collision avoidance. But it
seems it is not doing it efficeintly.
My question is that when I call send of ActiveMessage
to send a packet, will it use proper CSMA/CA at MAC
level to avoid any collision and packet losses?? OR I
need to use a random delay to call send at application
level (i.e my routing layer)??
Also if anyone can provide some guidelines about
avoiding packet losses in a multihop environment.
-Regards
