3 ASNA History : Mobile Health Wireless Health Broker & Service Provider Mobile Networks Doctor Vital Signs User data Analysis & Content Management Hospital Patient Feedback Loop in Real-Time

4 ASNA M-health Results  for commercial use  highly profit oriented  pre-configured  Certification  New features coming from research  medical research  non-profit oriented  open system, dynamically adaptable  No certification  New, customized features can be commercialized after validation Research System Commercial System

5 ASNA What is next ?? From the research point of view:  Add context awareness for mobile patients  Provide means for fine grain wireless networks’ QoS information  Automatic analysis of incoming vital signal measurements From the commercial point of view  Transfer research results to commercial product

6 ASNA Research Subjects at ASG  Quality of Service  How the application/user/service anticipate the available QoS of a wireless network?  Trust of spatial information  Can we trust the spatial information coming from a mobile device?  Hovering Information  Can server free spatial information exist? Research Subjects at ASG  Mobile Health  Context aware services and applications

7 ASNA mobile game user application server Internet 2.5G / 3G / WLAN /… Mobile Operator Network Enterprise Network Development of E2E QoS-forecast service Towards QoS-and context-aware mobile applications Goal: to know and adapt to the forecasted E2E QoS E2E QoS forecast service log / request E2E QoS info Problem: no guarantees + no knowledge on E2E QoS

8 ASNA E2E QoS depends on: user location, time and mobility level mobile operator, wireless technology …other user-context … working day lunch-time weekend day lunch-time Forecasted E2E QoS ! Development of E2E QoS-forecast service Towards QoS- and context-aware mobile applications

9 ASNA Trust and Security in Spatial Messaging  Problem Spatial messaging has little success because the lack of a trust mechanism prevents lots of serious applications.  Our target GeoVTag, a framework that adds trust information on each message, so that a user can define how trustworthy a given message is (according to his trust relationships and his current context). Pilot application : FoxyTag : ( a free, legal and collaborative system to signal radars on mobile phones anywhere on the planet!

10 ASNA Hovering information (p a0,t 0 ) (p b0,t 0 ) (p a2,t 2 ) (p a0,t 0 ) (p a1,t 1 ) (p a4,t 4 ) (p a3,t 3 ) In the absence of fixed infrastructure, hovering information will use all devices in its neighbourhood such as phones, RFIDS, sensors, PDAs, laptops, PCs, etc Hovering information (blue) will be linked to a location and optionally time stamped (p a0,t a ). Physically, this information will reside in neighbouring devices (pink) Hovering information (blue) will be capable of moving from one location to another (from p a0 to p a4 ) jumping across the intermediate physical devices (pink) Hovering information Mobile device / user

11 ASNA Hovering Information Hovering Information features:  Linked to a geographical location - Hovering autonomously from one mobile device to another  Moving from a geographical location to another  Existence of its own once created  Existence in a dynamic distributed heterogonous environment with no centralized servers
