Location in Context Aware Service Discovery
Student thesis: Master thesis (including HD thesis)
- Gorka Mateo Chinchilla
Context Aware Service Discovery is an extension
to Service Discovery that uses context information
to offer the best service to the user.
Context Aware Service Discovery can for example
use the location information of devices and
services connected to the network as a context
information to find nearest service. For the System
in this report, there has been designed an
interface between a Context Aware Service Discovery
System, and a general Location Platform,
which has been implemented using a Position
System based on Bluetooth Signal Strength technique.
For the design there has been carried out
a study about the accuracy in the major wireless
localization techniques and it has been defined
an accuracy of the location, in order enable the
Context Aware Service Discovery to efficiently
use this additional information to the location itself.
Finally there has been carried out measurements
with the implementation of the designed
interface, regarding the generated delay and traffic
in the System and the service’s selections of
the Context Aware Service Discovery. Results
shows that the discovery time and the generated
traffic increase linearly by a factor of 1400 and
72 respectively with the number of devices in the
cluster and the wrong selections at cluster level
are less than 25%.
