ABSTRACT:
A system and method to avoid and control the bottleneck points in multi-hop wireless ad-hoc networks is described. This is achieved by using the overheard RTS/(N)CTS information to compute a weighted combination of the node's and neighbors weighted queue size. Rate limiting factor can be distributed by using ACK messages in case RTS/CTS is not enabled while node weight values can be distributed in DATA messages. Furthermore, rate limiting is based on two metrics that eliminate the problems of drop-tail schemes. Priority levels may be used for selective rejection to provide availability for emergency and system packets.
