Duty-Cycle Wireless Sensor Networks for Critical Infrastructures
We focus on Duty-Cycle Wireless Sensor Networks (DC-WSNs) as a sustainable, emerging technology suitable for remote and unattended monitoring of Critical Infrastructures (CI). CI are physical and information networks, services and assets which, if disrupted or destroyed, would have a serious impact on the health, safety, security or economic well-being of citizens. If deployed on a Critical Infrastructure, the DC-WSN provides a sustainable monitoring facility that conveys different kinds of sensed data to a centralized operating center or, in case of major damages, the DC-WSN can continue its tasks in unattended mode.
In this talk, we consider DC-WSNs populated by a large number of tiny sensors and by few more powerful devices, called actors. The anonymous and energy-constrained sensors are distributed at random in a wide area and operate according to different sleep-awake schedules. The actors are authorized to organize the sensors into their vicinity into short-lived actor-centric sensor networks.
For such DC-WSNs, we propose centralized and semi-distributed protocols for (i) sensor localization and (ii) data dissemination. The sleep-awake schedules and the density of the WSN are the network parameters in our model. The percentage of sensors localized, of sensors to which data are distributed, the time delay to achieve it, and the power consumption of the whole network are the performance metrics used in the analysis of our protocols.

Yet another monetization scheme for Info-plosion
Information explosion(Info-plosion) is one of the most notable phenomenon in 21st century. Search engine companies invented how to monetize the search keywords. This talk will introduce a yet another efforts to monetize the human activities done in Info-plosion and Info-Grand Voyage projects in Japan. In digital helper experiments, we extracted movement pattern from 3000 participants with GPS mobile phones, which significantly improved the convergence. In experiments on healthcare for metabolic syndrome, we did the mining against activity information from accelerometer sensors and found the recommendations based on it were quite useful for life style related disease. In both experiments, info-plosion and its analytics were a key enabler.
