Our mission is to explore and develop technologies that will be available in the marketplace in five to ten years - not just novelties, but technologies that will see mass market demand from consumers and enterprises.
NRC has been exploring and developing mobile technologies for over 20 years. Always seeking to go beyond the state of the art, we embrace open collaboration and partnering for greater innovation - as we lead Nokia's transition to an Internet company with increased ambition, focus, and long term perspective, our doors are open to ever-increasing possibility.
This website provides an expanding information portal for the Center's research scientists and engineers. This window enables us to share some of our more recent ideas and experiences with other researchers who might want to discuss topics of mutual interest. We invite you to browse and email anyone of us for further discussion.
Delay tolerant networks (DTNs) are networks whose nodes have low connectivity and/or unreliable links. Because of these characteristics, DTN nodes use a store-carry-and-forward technique to deliver data through the network. Communication over DTN relies on intermediate nodes sharing their resources and can be abused by resource hogs, i.e. individuals who generate messages at a rate that is much higher than the average.
State-of-art automatic analysis tools for personal audio content management are discussed in this paper. Bayesian networks based audio classification algorithm provides classification into four main audio classes and serves as a first step for other subsequent analysis tools. For speech analysis we propose an improved BIC based speaker segmentation and clustering algorithm and a combined gender and emotion detection algorithm utilizing prosodic features. For the other main classes it is often hard to device any general and well functional pre-categorization that would fit the unforeseeable types of user recorded data.

Call for proposals for research groups [DL: 29.08.2008]
PeC Laboratory annonces a Call for Proposals to gather new innovative ideas for high quality, high impact research projects. We are looking for proposals from the following areas:
Context aware services and applications
Users are frustrated by the current experience of browsing, downloading, and exchanging
files in low-bandwidth networks, such as ad hoc wireless networks. One improvement to this
experience is to let users first locally interact with file thumbnails - graphical summaries
of file contents - and fetch complete files only if necessary. These thumbnails can be
sent quickly over the network and augment traditional metadata, such as file names and
ownership.
Mobile RFID services for Internet of Things can be created by using RFID as an enabling technology on mobile devices. Humans, devices and things are the content providers and users of these services. Mobile RFID services can be provided either on mobile devices as stand-alone services or combining with end-to-end systems. When different service solutions are considered, there are more than one possible architecture solution in the network, mobile and the back-end server areas. Combining the solutions wisely by applying the software architecture and engineering principles, a combined solution can be formulated for certain application specific use cases. This paper illustrates these ideas to create some reference solution models.
