Welcome from the Technical Program Chairs

IEEE International Conference on Pervasive Computing and Communications (2012)

Albrecht Schmidt Jie Liu George Roussos Alexander Varshavsky

A warm welcome to the Tenth Annual IEEE International Conference on Pervasive Computing and Communications (PerCom 2012). We are very excited to introduce you to the technical program of our conference that this year includes 28 papers representing high-quality research conducted over the broad spectrum of topics related to pervasive computing.

Scalable ID/Locator Resolution for the IoT

George Roussos Paul Chartier

Identifier-locator separation is a mechanism that has been used successfully to support fine-grain object mobility and persistence. Support for legacy identification systems is seen as critical for the rapid adoption of the IoT. Thus, network-based identifier resolution and meta-data discovery services are already widely recognized as one of the core ingredients of the IoT architecture. This paper introduces a secure and scalable approach for the provision of such services derived as an application of the Handle System, which is extended with the components required for ID/Locator resolution on the IoT. This scheme is applicable to practically any IoT-based ID/Locator specification incorporating those established for different flavors of RFID and wireless sensor networks, and supersedes previous proposals such as the Object Naming and the OID Resolution Service. To highlight its advantages, we deploy our scheme to the long-standing artifact identification scheme specified under ISO/IEC 9834. In particular, we introduce a mapping for embedding OID Unique Item Identifiers in the Handle address space, several new HDL data-types defined so as to address common information provision needs in this context, and outline operational and use considerations. We conclude that the approach proposed here supports object mobility, fine-grain security compatible with international IoT requirements, especially with regards to governance, and multiple domains of control at the item level combined with superior scalability both with regard to identifier address space and system size.

Spectrum-aware wireless sensor networks

Peng Du George Roussos

Wireless sensor networks (WSN) are one of the enabling technologies for the Internet of Things. Due to the restricted capability of sensor, the performance of WSN is sensitive to interference from nearby wireless devices utilizing the same band. The channel hopping technique is adopted by IEEE 802.15.4e standard to mitigate such adverse effect. In this paper we propose the Adaptive Time-slotted Channel Hopping (A-TSCH) framework which augments standard IEEE 802.15.4e channel hopping with mechanisms for learning the spectral condition and blacklisting. Complete design and implementation are provided, followed by analysis of experimental results. We discover that A-TSCH improves the packet delivery in the presence of interference from co-located devices, leading to substantially enhanced reliability of WSN based on IEEE 802.15.4e.

A case study in pervasive retail

George Roussos Juha Tuominen Leda Koukara Olli Seppala Panos Kourouthanasis

In this paper we discuss the rationale for the development of MyGrocer, a second-generation pervasive retail system, as well as its implications for the fast moving consumer goods (FMCG) sector. We will only touch upon the technology infrastructure and the required technical developments since these have been discussed extensively elsewhere. The focus here is on the one hand, on the analysis of the business forces that dictate the development of pervasive retail and on the other, the implications and the opportunities for innovative business models offered by the dis-intermediation effect of pervasive retail on the supply chain of FMCG. The MyGrocer system has undergone two phases of field-testing and is expected to be fully operational by the end of this year. The development of the MyGrocer architecture is a collaborative effort between industry and academia within Europe.

PDKit: A data science toolkit for the digital assessment of Parkinson’s Disease

PLoS Computational Biology (2021)

Cosmin Stamate Joan Saez Pons David Weston George Roussos

PDkit is an open source software toolkit supporting the collaborative development of novel methods of digital assessment for Parkinson’s Disease, using symptom measurements captured continuously by wearables (passive monitoring) or by high-use-frequency smartphone apps (active monitoring). The goal of the toolkit is to help address the current lack of algorithmic and model transparency in this area by facilitating open sharing of standardised methods that allow the comparison of results across multiple centres and hardware variations. PDkit adopts the information-processing pipeline abstraction incorporating stages for data ingestion, quality of information augmentation, feature extraction, biomarker estimation and finally, scoring using standard clinical scales. Additionally, a dataflow programming framework is provided to support high performance computations. The practical use of PDkit is demonstrated in the context of the CUSSP clinical trial in the UK. The toolkit is implemented in the python programming language, the de facto standard for modern data science applications, and is widely available under the MIT license.

Ubiquitous Computing and Databases

IGI Global eBooks (2011)

George Roussos Michael Zoumboulakis

The concept of the so-called ubiquitous computing was introduced in the early 1990s as the third wave of computing to follow the eras of the mainframe and the personal computer. Unlike previous technology generations, ubiquitous computing recedes into the background of everyday life: It activates the world, makes computers so imbedded, so fitting, so natural, that we use it without even thinking about it, and is invisible, everywhere computing that does not live on a personal device of any sort, but is in the woodwork everywhere.
