Wireless data networks are increasingly becoming an important part of the next-generation network infrastructure. This is made possible by the availability of inexpensive wireless network devices such as Bluetooth [1] and wireless LANs [20]. The objective of these networks is to provide users with “anytime, anywhere” data access. The end-user devices range from small handheld PDAs to larger laptops. | Handbook of Wireless Networks and Mobile Computing Edited by Ivan Stojmenovic Copyright 2002 John Wiley Sons Inc.

The objective of these networks is to provide users with anytime anywhere data access. The end-user devices range from small handheld PDAs to larger laptops. The computing and storage capabilities of these devices cover a wide spectrum. One of the chief limitations of these wireless networks is the limited battery power of thAtetwork nodes.TVerefore power management is one of the challenging problems in wireless communication and recent research has addressed this problem.
