The very heart of VSNs'' vision is the capability to dynamically allocate shared physical resources (processing power, bandwidth, storage) to multiple incoming applications. In this context, we tackle the problem of optimally allocating shared resources in VSNs by proposing an efficient greedy heuristic that aims to maximize the total revenue out of the deployment of multiple concurrent applications while considering the inherent limitations of the shared physical resources. The proposed heuristic is tested on realistic network instances with notable performances in terms of execution time while keeping the gap with respect to the optimal solution limited (below 5% in the tested environments). 000063088 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/TEC2014-52969-R$$9info:eu-repo/grantAgreement/ES/DGA/T98 000063088 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000063088 655_4 $$ainfo:eu-repo/semantics/conferenceObject$$vinfo:eu-repo/semantics/acceptedVersion 000063088 700__ $$aCesana, Matteo 000063088 700__ $$0(orcid)0000-0001-9052-9554$$aOrtín, Jorge$$uUniversidad de Zaragoza 000063088 700__ $$0(orcid)0000-0002-0719-7198$$aDelgado, Carmen$$uUniversidad de Zaragoza 000063088 700__ $$0(orcid)0000-0002-8682-745X$$aGallego, José Ramón$$uUniversidad de Zaragoza 000063088 700__ $$0(orcid)0000-0002-8298-4300$$aCanales, María$$uUniversidad de Zaragoza 000063088 7102_ $$15008$$2560$$aUniversidad de Zaragoza$$bDpto.
