Abstract
In this paper we present a method for reconfiguring
Virtual Objects (VOs) during run-time. VOs are semantic
descriptions of ICT objects and the associated physical
objects and phenomena they observe. VOs also include
software modules to expose ICT object functionalities as
IoT services for re-use. In our case study we show, by
using an analytical model, how the energy efficiency of a
wireless battery powered weather station (WS) can be
improved. We introduce descriptions of the available
operating modes and store them in the WS semantic
description. These operating modes of the WS's VO are
linked with the ability of the ICT object to change the
compression method used to transmit information during
run-time. We evaluate the energy efficiency and latency
of three operating modes, namely uncompressed, lossy and
lossless modes. The results show that the possibility to
re-configure the operating mode during run-time from
uncompressed to lossy mode lowers the total energy for
transmission to 47.9%
