Introduction

Mobile technologies are the future business commitment, as they allow all members of the enterprise to access relevant information to perform their duties without being enslaved to the cable. Wireless and mobile technology has been advancing at an unparalleled rate, and its impact is being observed in many facets of our daily life. Mobile and wireless systems are currently used in commerce, education, defence, and many high-risk fields, including nuclear power, aviation, and emergency medicine (Malladi,2002,144-146). The technology can be used in home-based and industrial systems as well as in commercial and military environments. When we speak of mobile computing, mobility means having the ability to access online resources and services while moving from one geographic location to another. Prior to the advent of mobile computing, a user accessed online resources through a dial-up modem (which sends and receives information over phone lines), a cable modem (which sends and receives information over the same cable that cable television networks use) or various other wire-based media, including DSL (short for digital subscriber lines) and ISDN (integrated services digital network).
