Hi, I have AntNet routing protocol implemented in a 15-node wired topology. My aim to do a congestion notification and avoidance so i created a scenario where 2 source nodes start sending data towards the node sink in a way that it creates congestion in one of the intermediary node. What i want to do is to implement a congestion notification based on say queue occupancy, notification that will be sent to the source nodes in order to anticipate congestion. After recieving it, source nodes will adjust their transfer rate (lowering it of course). Can anybody help me in doing so?
