At IC-UWB to Present ISMB Ultra-Wideband Results Within the BUTLER Project

29 August 2014

ISMB will participate in the 2014 edition of the IEEE International Conference on Ultra-Wideband (IC-UWB) which will be held on 1-3 September 2014 in Paris (France). This conference focuses on the latest UWB systems, technologies and field of applications. In addition, IC-UWB includes original research and developments in UWB related field of application: cognitive radio, sensor networks and Internet of Things (IoT).

At the conference Francesco Sottile, the head of IoT Objects & Platforms Research Unit – part of the Pervasive Technologies (PerT) Research Area – will present a paper in the field of cooperative localization in presence of Non Line of Sight (NLoS) conditions, typical of indoor environments, which heavily affect the localization accuracy.

The paper (A Cooperative NLoS Identification and Positioning Approach in Wireless Networks) first analyzes the lower bound on the localization estimator in presence of NLoS measurements and then proposes a cooperative positioning algorithm based on the belief propagation theory, where mobile nodes cooperate among them by exchanging aiding information to improve the performance.

The results of the activities were carried within the BUTLER project, partially funded by EU under the FP7-ICT-2011. In particular, BUTLER develops the enabling technology to harvest and integrate existing art on context-awareness, towards a secure and pervasive system and services for/over the IoT.
