Wei Tai, Rob Brennan, John Keeney, Declan O'Sullivan, An Automatically Composable OWL Reasoner for Resource Constrained Devices, Third IEEE International Conference on Semantic Computing, 2009 (ICSC '09), Berkeley, CA, USA, 14-16 September, IEEE, 2009, 495-502
Centralized semantic sensor network systems
gradually show performance degradation as the scale
of the sensor network increases. Thus systems based on
distributed approaches with local, autonomous
management features are urgently required. In order
to achieve local autonomy, it is necessary to push
semantics towards the edge of the sensor network, but
this is hampered by the lack of availability of
lightweight ontology processing and reasoning
technologies that are cognisant of the limited
resources available in sensor network nodes. This
paper proposes an approach to dynamically and
automatically compose an ontology reasoner to
provide only the level of OWL reasoning required for a
given application. A design and prototype
implementation are presented, with initial evaluations
confirming that this approach saves memory without
loss of reasoning ability, which facilitates OWL
reasoning on the resource constrained devices typical
in sensor networks.
