In this paper, we show how statistical decision theory can be used to solve real life product problems. Global Positioning System (GPS) performance in a mobile handset degrades whenever it is simultaneously used with a 3G data or voice service. This degradation is due to the 3G transmitter interference. Mitigation methods to interference in GPS have been proposed. However, most of these methods...

Multimedia services such as streaming video and downloadable music are driving revenues and handset turnover in the 3G wireless world. The critical factor, as always, is the quality of the end-user experience. Users won't pay for premium services if the quality and functionality fall below their expectations. Extensive testing is the key to delivering high-quality services and devices. But mult...

Nowadays, travelling from one place to another became easier than before. This is due to the availability of Electronic maps and guidance systems for different users. Despite the progress a...

The aim of this paper is to propose a computation offloading strategy, to be used in mobile cloud computing, in order to minimize the energy expenditure at the mobile handset necessary to run an application under a latency constraint. We exploit the concept of call graph, which models a generic computer program as a set of procedures related to each other through a weighted directed graph. Our ...

The mobile communications industry will experience an evolutionary step within the next two years with the introduction of third generation mobile networks, completing the handset transition from a purely telephony device of the first generation analogue networks into a multimedia multi-purpose mobile communications tool. The ability of these new handsets to store and access sensitive informati...
