A Medium Access Control Scheme for Wireless LANs With Constant-Time Contention

In today's wireless networks, stations using the IEEE 802.11 Standard contend for the channel using the Distributed Coordination Function (DCF). Research has shown that DCF's performance degrades especially with the large number of stations. This becomes more concerning due to the increasing proliferation of wireless devices. In this paper, the authors present a Medium Access Control (MAC) scheme for wireless LANs and compare its performance to DCF and to other efficient schemes. The scheme, which attempts to resolve the contention in a constant number of slots (or constant time), is called CONTI. The contention resolution happens over a pre-defined number of slots.
