Introduction

Ad hoc networks have received growing research attention during the last decade. This is partly due to significant developments in local area wireless technologies that are now starting to enable low cost wireless network build-out for local area communications. Such networks are emerging first of all in corporate environments especially through WLAN technologies, and similarly WLAN is also taking more and more footprint in residential solutions. Another wireless trend is happening through even lower cost wireless technologies such as Bluetooth, which is currently emerging in the mobile phone area. Both of these wireless technologies will be expanding into new arenas and new capabilities are continuously developed for them in standardization bodies.

This seminar focused on the latest developments in ad hoc mobile wireless networks. Thus, building on the technical enhancements provided by the local area wireless technologies, the network level developments are at the core here.

We start by presenting a short overview on selected radio technology developments: WLAN and Ultra Wide Band radios. Ultra Wide Band is currently receiving a lot of attention after the US regulation authorities allowed limited research usage of it in 2002. The next topic area is ad hoc routing. Ad hoc routing has gained significant research interest even though it is not really in active usage outside research trials. From routing we move on to service discovery, which is not such a hot research topic even though its relevance in ad hoc mobile wireless networks will be crucial. Two service discovery technologies are included here: Universal Plug and Play from Microsoft and Jini technology from Sun. Application-level interworking is addressed through Session Initiation Protocol (SIP) that is a kind of basic call control protocol in IP networks. Finally security and trust issues are discussed. Perceived trust will be an important issue in the future when people navigate through wireless networks where the virtual experience will be changing with respect to time and place.

The seminar took a holistic viewpoint to ad hoc mobile wireless networks, covering issues from radio technologies, routing, service discovery, application interworking and trust. The picture is broad and thus it was possible to include only a small snapshot of the relevant research developments. Similar topic areas will be covered in the future seminars with a new selection of research developments.
