abstract
Wireless communication[1][2] between mobile users is becoming more popular than ever
before. This is due to recent technological advances in laptop computers and wireless
data communication devices, such as wireless modems and wireless LANs[3]. This has
lead to lower prices and higher data rates, which are the two main reasons why mobile
computing continues to enjoy rapid growth.
There are two distinct approaches for enabling wireless communication between two
hosts. The first approach is to let the existing cellular network infrastructure carry data
as well as voice. The major problems include the problem of handoff, which tries to
handle the situation when a connection should be smoothly handed over from one base
station to another base station without noticeable delay or packet loss. Another problem
is that networks based on the cellular infrastructure are limited to places where there
exists such a cellular network infrastructure.
The second approach is to form an ad-hoc network among all users wanting to
communicate with each other. This means that all users participating in the ad-hoc
network must be willing to forward data packets to make sure that the packets are
delivered fro m source to destination. This form of networking is limited in range by the
individual nodes transmission ranges and is typically smaller compared to the range of
cellular systems. This does not mean that the cellular approach is better than the ad-hoc
approach. Ad-hoc networks[4] have several advantages compared to traditional cellular
systems. These advantages include:
