Introduction to Mobile Computing 

Mobile Computing is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link. This tutorial will give an overview of Mobile Computing and then it will take you through how it evolved and where is the technology headed to in future along with the classifications and security issues involved.

The process of computation on a mobile device. 

• In mobile computing, a set of distributed computing systems or service provider servers participate, connect, and synchronize through mobile communication protocols.

• Mobile computing as a generic term describing ability to use the technology to wirelessly connect to and use centrally located information and/or application software through the application of small, portable, and wireless computing and communication devices.

• Provides decentralized (distributed) computations on diversified devices, systems, and networks, which are mobile, synchronized, and interconnected via mobile communication standards and protocols.

 • Mobile device does not restrict itself to just one application, such as, voice communication.

• Offers mobility with computing power • Facilitates a large number of applications on a single device

Limitations to mobile computing

• Resource constraints: Battery
• Interference: the quality of service (QoS)
• Bandwidth: connection latency
• Dynamic changes in communication environment: variations in signal power within a region, thus       link delays and connection losses …
• Resource constraints: Battery • Interference: the quality of service (QoS)
• Bandwidth: connection latency
• Dynamic changes in communication environment: variations in signal power within a region, thus      link delays and connection losses …
• Network Issues: discovery of the connection-service to destination and connection stability
• Interoperability issues: the varying protocol standards
• Security constraints: Protocols conserving privacy of communication .
• Mobile computing ─ ability to use the technology to wireless connect to and use centrally located information and/or application software through the application of small, portable, and wireless computing and communication devices voice, data and multimedia communication standards.
