Consisting of 25 articles contributed by expert authors from around the world, this handbook begins with a detailed introduction that provides an overview of LAN technologies, performance, security, and security protocols. It then delves further into WLAN technology, covering space-time processing, WLAN and cellular convergence, and a peer-to-peer approach to roaming, along with other topics. The Handbook continues by exploring WLAN applications, followed by an extensive discussion of security that includes the steps that can be taken to minimize WLAN security risks. This text concludes with an analysis of standards, describing 3G UMTS - IEEE 802.11b internetworking and security.
Wireless networks have recently received much attention. Support for
mobility in Internet access is gaining significant interest as wireless/mobile
communications and networking are proliferating, especially boosted by
the widespread use of laptops and handheld devices.
Wireless LANs can be classified into two broad categories — infrastructured and infrastructureless
(ad hoc). In certain wireless networks, one hop is needed to
reach the mobile terminal. Ad hoc networks normally require a multi-hop
wireless path from the source to the destination. Interest in such networks
is increasing day by day.
