In this paper, a new delay-enabled EDCF for the transport of real-time traffic over an IEEE802.11e wireless LAN is proposed. The proposed technique will drop any packet belonging to a conversational class when a maximum queueing delay is reached. The packets belonging to an interactive or a background class are not dropped due to the queuing delay. The performance of this new technique is evaluated...
In this paper, we analysis the average packet delay on IEEE 802.11 DCF under unsaturation traffic in multi-hop ad hoc networks. We employ a Markov chain model to analysis the probability of transmission at each node in an arbitrary slot, and derive the channel access delay. We model each node using an M/G/1 queue and derive the queueing delay. The model is extended from analyzing the single-hop average...
