Mobile communication is the basis for one of the fastest growing business areas at the beginning of the 21 st century. With IMT-2000 (International Mobile Telecommunications 2000), high-speed communication is possible anywhere, at any time, to any communication partner, with almost any device. As IMT-2000 comprises a set of different networking technologies, it provides a communication framework in which a subscriber may freely roam without having to be concerned about which network to use [1]. Hand-over procedures seamlessly integrate in-house networks, campus-based networks, metropolitan and wide area networks.

An application domain that makes use of wireless sensor network technology can be found in the area of medical monitoring. This field ranges from monitoring patients in the hospital using wireless sensors in order to remove the constraints of tethering patients to big bulky, wired monitoring devices to monitoring people in their everyday lives to provide early detection and intervention for various types of disease. This paper discusses scenarios where these sensors which vary fromminiature, body-worn sensors to external sensors such as video camera or positioning devices are applicable and presents a report of ongoing research on telemedicine at FUTA Akure.

An emerging trend in Social Networking sites and Web portals is the opening up of their APIs to external application develop- ers. For example, the Facebook Platform, Google Gadgets and Yahoo! Widgets allow developers to design their own applications, which can then can be integrated with the platform and shared with other users. However, current APIs are targeted towards develop- ers with programming expertise and database knowledge; they are not accessible to a large class of users who do not have a programming/database background, but would nevertheless like to create new applications. To address this need, we have developed the AppForge system, which provides a WYSIWYG application development platform. Users can graphically specify the components of webpages inside a Web browser, and the corresponding database schema and application logic will be automatically generated on the fly by the system.

Facebook is one of the most popular Internet sites today. A key feature that arguably contributed to Facebook’s unprecedented success is its application platform, which enables the development of third-party social-networking applications. Understanding how these applications are installed and used is important for the function and utility of web-based online social networks, e.g. to better engineer them and/or to design advertising campaigns.

The rapid advent of “Web 2.0” applications has unleashed new HTTP traffic patterns which differ from the conventional HTTP request-response model. In particular, asynchronous pre-fetching of data in order to provide a smooth web browsing experience and richer HTTP payloads (e.g., Javascript libraries) of Web 2.0 applications induce larger, heavier, and more bursty traffic on the underlying networks. We present a traffic study of Web 2.0 applications including Google Maps, modern Web-email, and social networking Web sites, and compare them with all HTTP traffic. We highlight the key differences of Web 2.0 traffic from traditional HTTP traffic through statistical analysis. As such our work elucidates the changing face of one of the most popular application on the Internet: The World Wide Web.

This chapter provides a (necessarily) brief introduction to computer networking concepts. For many applications of gawk to TCP/IP networking, we hope that this is enough. For more advanced tasks, you will need deeper background, and it may be necessary to switch to lower-level programming in C or C++.

There are two real-life models for the way computers send messages to each other over a network. While the analogies are not perfect, they are close enough to convey the major concepts. These two models are the phone system (reliable byte-stream communications), and the postal system (best-effort datagrams).

2007 has been a great year for the Web. On the one hand, there has been an upswing in the number of Web 2.0 start- ups globally, while on the other hand, popular Web 2.0 start-ups like Facebook, jaiku, feedburner and others have been acquired or invested in by the giants of the Web like Microsoft and Google. Closer home in India, the trends have been similar, though still in a nascent stage, as social networking became a buzzword with Orkut. That led to start-ups like Minglebox (which obtained funding from Sequoia Capital), BigAdda (backed by Reliance), Desimartini (recently acquired by HTMedia), and many others. Though launches occurred at a lower frequency than in the US, India has seen over 150 Web 2.0 start-ups launched during this year (according to internal research at WATConsult) in different spaces from social networking, social bookmarking and blogging, to media sharing, local search, etc. Let’s take a look at some of the…

Many IT organizations view the phrase Web 2.0 as either just marketing hype that is devoid of any meaning or they associate it exclusively with social networking sites such as MySpace. That’s understandable as Web 2.0 is not the same as a new protocol that has an associated RFC that spells out definitively what is and what is not included as part of the protocol. As a result, many concepts get lumped under the banner of Web 2.0. In one of the most insightful analyses of Web 2.0, Tim Reilly points out that Web 2.0 involves fundamentally new design patterns and business models and he compares companies that were successful with Web 1.0 with those companies that are leading the movement to Web 2.0.
