The wireless network has seen an exponential growth due to its ability to free its user from the expenses and hassles in setting up their infrastructure. Such growth is more spectacular in the emerging economies where there was minimal or no presence of wired communication infrastructure in the past. Reputable market research firms have identified that the wireless network users will grow by a factor of 8 by 2007 (Gartner, Inc., March 26, 2003), while wireless product shipments grew by 73% in 2002 (Dataquest Inc., September 19, 2002). Even a small fraction, such as 1%, of the broadband network market is a significant figure for a viable medium sized business. Despite many new advances in technology, consumers are dependent on the infrastructures of large companies to satisfy their need. The performance of centralized and large-scale networks could be significantly curtailed at a time of congestion, or completely lost due to natural or unnatural disasters. There are numerous applications of a communication network whose operation does not depend on such large-scale infrastructure and does not require any network administrator to configure the system at the end-user premises.
