Increasing Capacity in Dual-Band WLANs Through Ad-Hoc Networking (bibtex)
by Athanasios Vaios, Konstantinos Oikonomou, Nikolaos Zinelis, Ioannis Stavrakakis
Abstract:
The ad-hoc networking paradigm -- originally conceived to cope with infrastructureless military and emergency situations -- is also being considered to support the ever-evolving user requirements for higher data rates and enhance the capabilities of traditional networks. The Centralized Ad-Hoc Network Architecture (CANA) proposed in this article aims at increasing substantially the capacity of traditional Wireless Local Area Networks (WLANs). It is based on a dual frequency system in which the operation in the original WLAN frequency supports the centralization of some of the traditionally distributed and problematic ad- hoc functionalities enabled at the new frequency; higher- rate, shorter-range, peer-to-peer and multi-hop transmissions are possible at the new frequency, resulting in a significant increase of the WLAN capacity. In order to take advantage of the extra capacity, modifications are defined and described by exploring the HiperLAN/2 standard. The gain of the induced dual mode of operation depends on several parameters that define the performance of CANA. This article explores the performance issues that CANA arises by providing both analytical and simulation results. The overhead of CANA is rather low if one takes into account the profits of such architecture.
