This demo exhibits a new application of mobile ad-hoc networks, where, a group of mobile devices are connected to allow synchronized presentation of multimedia content. The demo is in the form of an interactive tour. Participants have a mobile device and the tour is led by a guide, who takes the group on an informative tour of a locale. The tour is augmented with the presentation of multimedia content on the devices, highlighting points of interest. Content presentation is controlled by the guide and is synchronized using the ad-hoc network. This is an edutainment application but the underlying technology could be applied elsewhere including educational settings and in entertainment.

IEEE 802.11 (Wi-Fi) is a standard feature on smart phones and an alternative to cellular networks for connectivity. Users can surf the Web, make VoIP calls and more from home Wi-Fi networks or public hotspots. At present this type of connectivity is intermittently available with limited mobility support. It is unclear if today's Wi-Fi scales for large number of users. We consider the challenges in providing Wi-Fi connectivity to mobile devices on a cellular network-like scale. The provision of quality services which rely on network connectivity, within entertainment parks is considered. Limitations of some existing communications technologies are examined and a number of important problems are quantified. Dual-radio and other solutions to the scalability problem are presented.

In order to accommodate the constantly growing number of vehicles on the road with which infrastructure provision is failing to cope, new means of optimizing the available road space are required. This paper presents a novel adaptive vehicle routing algorithm for TraffCon - an innovative Traffic Management System enabled by wireless vehicular networks. The algorithm combats the vehicular traffic congestion problem by seeking to optimize the usage of existing road capacity, while also minimising vehicle fuel consumption and emissions. Results demonstrate that the algorithm significantly increases road utilisation, reduces congestion, average journey times and fuel consumption in comparison with existing approaches.

Traffic congestion is a very serious problem which is becoming ever worse as the growth in the number of cars on the road significantly out-paces the provision of road capacity. This paper presents a novel vehicle routing algorithm for TraffCon - an innovative traffic management system for wireless vehicular networks - and discusses its complexity. The algorithm combats the traffic congestion problem by seeking to optimize the usage of the existing road capacity, reduce vehicle trip times and decrease fuel consumption and the consequent gas emissions. Results demonstrate that the algorithm significantly increases road capacity utilisation and consequently reduces traffic congestion in comparison with an existing approach.

Source-code examples of APIs enable developers to quickly gain a gestalt understanding of a library's functionality, and they support organically creating applications by incrementally modifying a functional starting point. As an increasing number of web sites provide APIs, significantlatent value lies in connecting the complementary representations between site and service - in essence, enabling sites themselves to be the example corpus. We introduce d.mix, a tool for creating web mashups that leverages this site-to-service correspondence. With d.mix, users browse annotated web sites and select elements to sample. d.mix's sampling mechanism generates the underlying service calls that yield those elements. This code can be edited, executed, and shared in d.mix's wiki-based hosting environment. This sampling approach leverages pre-existing web sites as example sets and supports fluid composition and modification of examples. An initial study with eight participants found d.mix to enable rapid experimentation, and suggested avenues for improving its annotation mechanism.
