Simulations are commonly used for this purpose, especially for large-scale environmental monitoring applications. However, it is difficult to evaluate energy consumption, processing and memory requirements before the algorithm is really ported to a real WSN platform. We propose a method for emulating the operation of collaborative algorithms in large-scale WSNs by re-using a small number of available real sensor nodes. We demonstrate the potential of the proposed simulation-driven WSN emulation approach by using it to estimate how communication and energy costs scale with the network’s size when implementing a collaborative algorithm we developed in for tracking the spatiotemporal evolution of a progressing environmental hazard. 5 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2014-05 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text WSN implementation Continuous object Tracking Energy consumption Environmental hazard http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6855232&url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel7%2F6844297%2F6853544%2F06855232.pdf%3Farnumber%3D6855232 333648 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2978/2/2978_1.70_%ce%91%ce%9d_4_5_14.pdf URI http://hdl.handle.net/10795/2978 LOMv1.0creator 2016-04-27T12:05:59Z LOMv1.0validator 2016-04-27T12:05:59Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
