Ontology based approach for home data management
• Sensors in smart homes• Provide various measurements from the surrounding environment• How to integrate the heterogeneous sensor data?
• Ontologies• Provide efficient and machine readable way of representing and sharing
knowledge• Enable automated context reasoning
• VantagePoint - the ontology based home management approach• Visualizes semantic context information• Integrates heterogeneous sensor data into
contextual models
• Experiments with sensor data• SimuContext virtual sensors emulate the behavior of life context sources• Carerider bed sensors collect versatile context data concerning the sleep of a
person• This data can be utilized when creating informative diagrams

Abstract In this work we describe an approach to indoor user localisation by combining image-based and RF-based methods and compare this new approach to prior work [1]. This paper details a new algorithm for indoor user localisation, demonstrating more effective user localisation than prior approaches and therefore presents the next step in combining two different technologies for localisation in indoor type environments.
System Overview
A Hybrid Method for Indoor User Localisation Milan Redžić, Ciarán Ó Conaire, Conor
Brennan, Noel O’Connor
RF localisation
where Si represents a location, 1 ≤ i ≤ I
and Oj is observed signal strength data from access point j, where 1 ≤ j ≤ J
Image matching and localisation The image matching uses the well-known SURF algorithm [2] which is implemented and installed on the N95 cell phone. An array of correct matches between given image and set of images is formed and max value indicates the image with most matches.
Experiments and Results Locations scattered throughout DCU(3 floors). Camaignr
software [3] was used. Photos from various angles, rotation, scale were captured. The hybrid technique is based on applying image matching on the smaller set of locations, which are generated by applying Bayesian analysis to the RF signal strength readings.

Image Data
Water management is an important part of monitoring the natural environment and includes monitoring the water quality of coastal and inland marine environments.
Visual sensing can help to overcome some of the problems associated with in-situ wireless sensor networks and provide context to what is being sensed.
The development of a smart multi-modal sensor network will lead to a more robust and effective environmental sensing system.
We report on our initial work on using visual sensing to monitor a river environment.

Direction
• Urban sensing systems enable us to obtain huge amount of environmental information. However, for using this system in navigation, vast information floods users’ understandability.• We focus on users’ mobility:
• How to obtain suitable surrounding information based on users’ mobility.• How to query for appropriate range of area and how to obtain detailed suitable information.
• We propose Speed-dependent information retrieving schema for mobile user navigation.• Our technical contribution is: Scaling search model, Priority-k method, and Map scale adjusting.
