A novel cooperative spectrum sensing algorithm is implemented and analyzed using Raspberry Pi. In the proposed setup, Nokia cell phone is used as a spectrum sensing device while Raspberry Pi functions as a FC device to collect sensing results from local sensing devices. The investigation results of the proposed setup show significant improvement in detection performance as compared to local spe...

ECSI (The Electronic Chips & Systems design Initiative) today is announcing the launching of the SYDIC-Telecom project, together with the major European telecommunication players: Alcatel, Bosch, Ericsson, Infineon, Intracom, Italtel, Nokia, Philips and VTT Electronics. The aim of SYDIC-Telecom is to define methodologies and techniques to facilitate System-on-Chip design adopting IP reuse, and ...

We present IYOUIT, a prototype service to pioneer a context-aware mobile digital lifestyle and its reflection on the Web. The application is based on a distributed infrastructure that incorporates Semantic Web technologies in several places to derive qualitative interpretations of a user’s digital traces in the real world. Networked components map quantitative sensor data to qualitative abstrac...

Measurements related to user expectations, behaviors and experiences can provide useful data to many roles and teams in a company. Each role provides different views to the question “what should be measured, and why?” We conducted an empirical study on user experience (UX) measurement needs at different units and levels in one corporate (Nokia) and asked which kinds of UX measurements would be ...

We analyse multimodal time-series data corresponding to weight, sleep and steps measurements, spanning 15000 users, collected across consumer-grade health devices by Nokia Digital Health Withings. We focus on predicting whether a user will successfully achieve their weight objective. For this, we design several deep recurrent architectures, including a novel cross-modal LSTM (X-LSTM), and demon...

This paper addresses the ongoing inventory activities within the ITEA MOOSE project. The inventory result will be a complete view on the application of methods, techniques and tools for software production within some of the leading European industrial companies within the embedded system field, such as Philips, Océ, ASML and Nokia. The current results are remarkable, as they confirm the cautio...

Energy consumption has been mostly neglected in network coding (NC) research so far. This work investigates several different properties of NC that influence the energy consumption and thus are important when designing NC systems for batterydriven devices. Different approaches to the necessary implementation of coding operations and Galois fields arithmetic are considered and complexity express...

This paper discusses collaboration problems in large organizations where systems development takes place in distributed projects. We describe an in-house collaborative design environment, which has been used in several units in the NOKIA corporation. This environment called Timbuktu is evaluated based on our understanding after several years’ consultation and interviews of knowledge sharing in ...

Mobile guide applications are among the most used applications in Today’s smartphones. These applications provide position information, map, directory services as well as guidance. Still there are many multimedia features that could be added to these applications. We present a user study on such applications, comparing the commercial Google Maps and Nokia Maps with two prototypes that we have c...

User traces are essential for analysis of human behavior and development of opportunistic networking protocols and applications. As user traces are collected with high granularity to apply them in diverse scenarios, they have a high complexity resulting from the large number of user states. We present MobReduce: a methodology for reducing the number of states in user traces. We apply MobReduce ...
