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.

Peer-to-Peer programming (P2P) has in recent years become a widely explored research area. With the evolution of wireless technology such as mobile phones, the idea to bring these two technologies together gives a new dimension to P2P communication, collaboration and resource sharing.

Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the “Social Web”, i.e. on Web 2.0 community sites, and this content is being annotated and commented upon. The ability to view an individual’s entire contribution to the Social Web would be an interesting and valuable service, particularly important as social networks are often being formed through created content and things that people have in common (“object-centred sociality”). SIOC is a Semantic Web research project that aims to describe online communities on the Social Web. This paper describes how SIOC and the Semantic Web can enable linking and reuse scenarios of data from Web 2.0 community sites, and introduces a SIOC Types module to further specify the type of content items and act as a “glue” between user posts and the content items created and annotated by users.

Prosuming is one of the magic activities of the Web 2.0. The idea that media con- sumers can become media producers has been validated with all its pros and cons in systems like YouTube and Flickr.com. There is a re-newed discussion about expert and amateur cultures or even cults [3]. Especially, making movies was thought to be an area where only teams of highly specialized experts equipped with a lot of money can produce high quality movies with a world-wide audience. But next to Hollywood other production centers emerged like ”Bollywood” in India or ”Nollywood” in Nigeria with local practices. YouTube has proven that amateurishly produced content can fascinate people on the Internet.

A network is simply two or more computers linked together so their files can easily be shared or transferred from computer to computer. The simplest network is the LAN, the Local Area Network. These computers are in the same office or building. A LAN can have virtually any number of computers. You make a LAN when you connect two computers together in your office or at home.

When the concept of a network without wires was first suggested more than two decades ago, it sparked the imagination of scientists, product vendors, and users around the globe eager for the convenience and flexibility of a free roaming conection. Unfortunately, as the variety of wireless solutions began to emerge, anticipation turned to disappointment.The first wave of solutions proved inadequate for the networking, portability, and security needs of a changing IT environment. While this has largely continued to be the case throughout the 1990s with most cell-based and office local area network (LAN)-based wireless technology deployments, great strides have been made specifically over the last two years to address the fundamental concerns impeding the full acceptance of wireless net- working in the mainstream of corporate IT departments and the small office.
