Integrating Sensor Streams in pHealth Networks

Abstract

Personal Health (pHealth) sensor networks are generally used to monitor the wellbeing of both athletes and the general public to inform health specialists of future and often serious ailments. The problem facing these domain experts is the scale and quality of data they must search in order to extract meaningful results. By using peer-to-peer sensor architectures and a mechanism for reducing the search space, we can, to some extent, address the scalability issue. However, synchronisation and normalisation of distributed sensor streams remains a problem in many networks. In the case of pHealth sensor networks, it is crucial for experts to align multiple sensor readings before query or data mining activities can take place. This paper presents a system for clustering and synchronising sensor streams in preparation for user queries.

Variable interactions in risk factors for dementia

“…Subsequently, the Profiler presents the participant with a series of goals to improve their brain-health and mitigate against those factors from which they are most at risk. This is fundamentally different to systems such as that described in [17] where data is automatically generated in a uniform manner by purpose-built devices. The In-MINDD project is now testing this prototype model to assess if a 6 month intervention with the online profiler and support environment can improve the level of dementia risk in those most susceptible [14].…”

Data transformation and query management in personal health sensor networks

“…As new sensors are added or modified, a template to interpret the sensed data is required, but without changing the system. A more detailed description of this process can be found in [22].…”

Using Sensor Networks to Measure Intensity in Sporting Activities

“…Templates are used to describe raw sensor sources. Together with a structural enrichment process, they form XML schemas and are used to populate these schemas with raw data so that they can be queried using XPath or XQuery [15]. Their goal is to ensure that the service componets are never required to change.…”
