MOBILE COMPUTING
MOBILE COMPUTING.ppt (Size: 1,013.5 KB / Downloads: 51) [attachment=29488] About Mobile Computing Special class of distributed systems Deals with the mobility of hardware, data and software in computer application Nodes can disengage from joint operations move freely in physical space and reconnect to possibly different segment of computer network. Goal of Mobile Computing To permit user and program to be more and more effective in an Environment that is characterized by uncertain connectivity and Heterogeneity without changes to the manner in which they connect. Mobile Computing Applications Information about hotels ,restaurant and local data about a locality. Information about roads and street in firefighter vehicles. An employee can connect to his company server while mobile and do his work in this way productivity increases ADAPTABILITY IN MOBILE COMPUTING APPLICATION –TRANSPARENT ADAPTATION . The system automatically handles changes in connectivity between hosts, and transparently decides when to propagate updates or invalidate and re-fetch stale data. Individual applications have no say in how to make use of available bandwidth etc. LAISSEZ-FAIRE ADAPTATION In such systems Application monitors the availability of resource and are solely responsible for coping with the consequences of mobility Impact Of Wireless Communication The New Networking Technologies Allow Spontaneous Connectivity Among Mobile Devices. Mobile Devces Can Become Both Source And Consumer Of The Information .There Is No Longer Distinction Between Clients And Server Instead Devices Are Now Peer. Devices Must Be Able To Cooperate With Others In Their Proximity In Order To Pursue Individual And Collective Tasks. Conclusion Mobile computing is the future vision of the world. As information can be accessed from anywhere, and from any terminal the need of more effective evaluation, has appeared. Query processor should have a flexible architecture to adapt device capabilities and heterogeneity.

Mobile computing.ppt (Size: 337.5 KB / Downloads: 39) Handoff In cellular telecommunications, the term handover or handoff refers to the process of transferring an ongoing call or data session from one channel connected to the core network to another. In satellite communications it is the process of transferring satellite control responsibility from one earth station to another without loss or interruption of service. Soft handoff Soft handover or soft handoff refers to a feature used by the CDMA and W-CDMA standards, where a cell phone is simultaneously connected to two or more cells (or cell sectors) during a call. If the sectors are from the same physical cell site (a sectorised site), it is referred to as softer handoff. Hard handoff In a mobile cellular communication network, a Hard handoff is a typical Handoff mechanism in a communication network which is designed to work by first breaking off from the initial connection with a base station before switching to another base station. This is done in order to retain communications in a session for mobile users after incurring a non perceptible and insignificant brief interruption. A Hard handoff is also referred to as “Break-before-Make” handover. Cellular architecture Concept of Cell In wireless telephony, a cell is the geographical area covered by a cellular telephone transmitter. The transmitter facility itself is called the cell site. The cell provided by a cell site can be from one mile to twenty miles in diameter, depending on terrain and transmission power. Several coordinated cell sites are called a cell system. When you sign up with a cellular telephone service provider, you generally are given access to their cell system, which is essentially local. When travelling out of the range of this cell system, the cell system can enable you to be transferred to a neighboring company's cell system without your being aware of it. This is called roaming service. Cellular networking A cellular network is a radio network made up of a number of radio cells each served by a fixed transmitter, known as a cell station or base station, these cells are used to cover different areas of a cell. advantage: Increase capacity Reduse power usage Better coverage

mobile computing.ppt (Size: 2.92 MB / Downloads: 30) INTRODUCTION: The main aspect of mobile computing system are their prevalent wireless network connectivity , their small size , nature use , power sources and functionalities of systems. HISTORY The first time we used ABACUS, which is used in 500 B.C. 1960`s military had been using various wireless communication. 1970`s communication satellites began to develop .with the help of new communication satellite , orality of service and readability improved. lates using cellular techno logic`s.. Bluetooth Bluetooth devices in the house are always communicating with one another as long as they are powered on. Each device sends out a signal, received by the other devices that are sending out their own signals. WI FI ( Wire Less Fiedlity ) Wi Fi wireless LAN technology basically allows you to connect to the internet without the use of any wires. Many people use home Wi-Fi networks which can connect multiple computers to each other, APPLICATIONS: For Estate Agents Emergency Services Police Incident Information Screen In courts In companies Stock Information Collation/Control Credit Card Verification

Mobile Computing.ppt (Size: 519 KB / Downloads: 25) What Is Mobile Computing? A simple definition could be:Mobile Computing is using a computer (of one kind or another) while on the move Another definition could be:Mobile Computing is when a (work) process is moved from a normal fixed position to a more dynamic position. A third definition could be:Mobile Computing is when a work process is carried out somewhere where it was not previously possible. Why Go Mobile? Enable anywhere/anytime connectivity Bring computer communications to areas without pre-existing infrastructure Enable mobility Enable new applications An exciting new research area Moving Object Databases (MOD) Deals with Mobile Objects whose geometry, position changes over time Traditional DBMS alone is incapable for this purpose MOD is built on top of existing DBMS to support a critical set of capabilities Query Language for MOD Regular query language (SQL) is nontemporal For MOD we need Spatial and Temporal Query language “Where is the nearest station?” “What is the distance of the closest taxicab?” Conclusion Mobile computing has severe limitations - however, it is far from impossible, and technology improves all the time Lots of challenges - some have (good) solutions, many others are still waiting to be solved
