Wireless networks, whether cellular networks or wireless local area networks (LANs), have rapidly become an indispensable part of our life. Evidence of this is the widespread usage of such networks in several areas such as office, home, universities, hot-spots such as airports and hotels etc. In addition, the widespread availability of miniature wireless devices such as PDAs, cellular phones, Pocket PCs, and small fixtures on buildings, sensors are one step towards making possible the vision of wireless ‘nirvana’ a reality. Wireless ‘nirvana’ is the state of seamless wireless operation where any wireless device would be able to connect to any other wireless device or network at any time, in any place while satisfying the requirements of the user of the device. But as is obvious, we are still a long way off from the goal of wireless nirvana.
