ABSTRACT

One of the key requirements for a robust IT infrastructure is the provision of extensive facilities that allow safe and secure dissemination, exchange, and archiving of critical information. Wireless systems have recently matured to a degree where they are complementing or even replacing the traditional wireline systems. As far as technological feasibility is concerned, communication bandwidth and computational prowess have advanced sufficiently to bring many E-commerce and E-government applications into the realm of possible deployment. This is particularly true in the case of static and mobile end users as well as smaller systems.
