Active Queue versus Passive Queue - An Experimental Analysis on Multi-hop Wireless Networks

Congestion occurs in the multi-hop wireless relay routers as the packet arrival rate outpaces traffic handling capacity. Congestion introduces packet loss, queuing delay and restraint formation of new connections in the networks. An intelligent queue management needed in the wireless relay routers that effectively regulate the queue accumulation and avoid network congestion. In this paper, an experimental analysis of active queue and passive queue carried out under multi-hop wireless relay network to study its robustness and limitations.
