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. 000071111 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T98$$9info:eu-repo/grantAgreement/ES/MICINN/TEC2014-52969-R$$9info:eu-repo/grantAgreement/ES/UZ/CUD2013-05 000071111 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000071111 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000071111 700__ $$0(orcid)0000-0002-8298-4300$$aCanales, M.$$uUniversidad de Zaragoza 000071111 700__ $$0(orcid)0000-0001-9052-9554$$aOrtin, J.$$uUniversidad de Zaragoza 000071111 700__ $$0(orcid)0000-0002-8682-745X$$aGallego, J.R.$$uUniversidad de Zaragoza 000071111 700__ $$aRedondi, A. 000071111 700__ $$aBousnina, S. 000071111 700__ $$aCesana, M. 000071111 7102_ $$15008$$2560$$aUniversidad de Zaragoza$$bDpto.
