Universidad de Zaragoza Energy-aware dynamic resource allocation in virtual sensor networks 2017 Access copy available to the general public Unrestricted Sensor network virtualization enables the possibility of sharing common physical resources to multiple stakeholder applications. This paper focuses on addressing the dynamic adaptation of already assigned virtual sensor network resources to respond to time varying application demands. We propose an optimization framework that dynamically allocate applications into sensor nodes while accounting for the characteristics and limitations of the wireless sensor environment. It takes also into account the additional energy consumption related to activating new nodes and/or moving already active applications. Different objective functions related to the available energy in the nodes are analyzed. The proposed framework is evaluated by simulation considering realistic parameters from actual sensor nodes and deployed applications to assess the efficiency of the proposals. info:eu-repo/grantAgreement/ES/DGA/T98 info:eu-repo/grantAgreement/ES/MICINN/TEC2014-52969-R info:eu-repo/grantAgreement/ES/UZ/CUD2013-05 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-8298-4300 Canales, M.
