ABSTRACT
The widening availability of mobile information systems is being driven by the increasing demand to have information available for users anytime, anywhere. As the availability of wireless devices and mobile services increases, so will the load on available radio frequency resources [13]. In fact, wireless and mobile hosts (MHs) are the fastest growing segment of the personal computer market but are not well supported by current network protocols including those in use in the Internet. Wireless networks have fundamentally different properties than typical wired networks, including higher error rates, lower bandwidths, nonuniform transmission propagation, increased usage costs, and increased susceptibility to interference and eavesdropping.
