Wireless multihop networks, also known as packet radio networks and ad hoc networks, hold great promise for providing easy to use mobile services for many applications, especially military and disaster relief communications. Such networks can provide robust communication, be rapidly deployed, and respond quickly in dynamic environments. However, effectively deploying and utilizing such networks poses many technical challenges. One such challenge is to make effective use of the limited channel bandwidth | Handbook of Wireless Networks and Mobile Computing Edited by Ivan Stojmenovic Copyright 2002 John Wiley Sons Inc.
