ABSTRACT
The desire and the necessity for accessing and processing information stored in computer networks `anytime and anywhere' has been the impetus for the growing interest in mobile computing research. Wired computing networks and end devices such as PCs and workstations have effectively extended the data-only networking capability of a few years ago to sophisticated multimedia networking. The cost of such transformation to the end user turns out to be very nominal. Undoubtedly the wireless access technology has given a big boost to mobile cellular telephony and data networking.
Processing general purpose multimedia information requires, besides higher bandwidth, means for controlling the available bandwidth and caring for quality of service issues. This problem is accentuated by the need for providing such service in the presence of wireless physical layer and host mobility. Thus, tetherless and ubiquitous mobile and wireless computing systems should carefully combine advances in computer networking and wireless communication. While several experimental mobile computing platforms have sprung up, much research is needed to overcome technological obstacles in low power system design, sustainable battery life, unreliability and limited bandwidth of the wireless channel.
INTRODUCTION
• Migration is important for survival, mobility originated from the desire to either to move towards resources or away from scarcity, mobile computing about both the physical and logical entities that move
• Physical entities are computers that change locations.
• Mobile agents can migrate over Internet but active applications can only move to a local cluster of computers.
• Mobile computing is a generic term describing one's ability to use technology while moving, as opposed to portable computers, which are only practical for use while deployed in a stationary configuration
• The term mobile computing is quite new and has no clear definition, although some studies have already tried to survey this fast-growing area of information technology. Mobile computing does not only involve mobile computing devices (laptops, notebooks, PDAs and wearable computers), which are designed to be carried around, but also the mobile networks to which these computers are connected. Mobile services are the third component, rounding out this definition of mobile computing.
HISTORY OF MOBILE COMPUTING
• The fascinating world of mobile computing has only been around since the 1990s. Since then, devices that have been developed for mobile computing have taken over the wireless industry. This new type of communication is a very powerful tool for both businesses and personal use.
• This actually used to mean radio transmitters that operated on a stable base, usually with the help of large antennas. 2 way radios used by police officers were also considered mobile technology but now, it means people can connect wirelessly to the Internet or to a private network almost anywhere. As long as a person has one of the devices capable of wirelessly accessing the Internet, they are participating in mobile computing.
ADVANTAGES OF MOBILE COMPUTING
Computers are one of the major inventions of the world. The invention of computer has changed the world. During these days every field of life seems to be computerized. Later in the 21st century a new technology was introduced in the world known as mobile computing. Now-a-days computers are modified into mobile computers known as laptops.
A small introduction of mobile computing is that you can do your work in motion. In simple words it means that you can do your work while sitting anywhere in the world. You do not have to sit at one place to do your work.
