Abstract
In this paper a comparison of decentralized and centralized Medium Access Control (MAC) protocols for multihop ad hoc wirless networks is carried out. The Carrier Sense Multiple Access (CSMA) scheme of the IEEE 802.11 contention-mode has been selected as the most prominent example of a decentralized protocol. The European wireless LAN system HiperLAN/2 is an example of a centralized system, in which one station organizes the access to the radio interface of all other stations within a certain area. It is shown how a centralized MAC protocol like the one of the HiperLAN/2 system can be enhanced to build a multihop wireless network. The advantages of such a system in terms of throughput due to a possible frequency re-use have to we weighted against the advantages of decentralized protocols in terms of spectrum efficiency and ease of network management.
