Analysis of 802.11 DCF With Heterogeneous Non-Saturated Nodes

Overview The successful deployment of IEEE 802.11 Wireless LANs has generated much interest in analytical models of network performance. The various physical layer standards that comprise the 802.11 family of protocols all rely upon the same medium access control (MAC) protocol, which is based on CSMA/CA. This paper presents a queueing model for a 802.11 wireless LAN under non-saturated conditions. The model discussed in this paper builds on previous work, but additionally takes into account heterogeneous arrival rates. In particular, the paper considers the case when there are two packet arrival rates in the network, with one set of stations generating packets at the lower rate and the rest generating packets at the higher rate.

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
