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). info:eu-repo/grantAgreement/ES/MICINN/TEC2014-52969-R info:eu-repo/grantAgreement/ES/DGA/T98 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/acceptedVersion Cesana, Matteo (orcid)0000-0001-9052-9554 Ortín, Jorge Universidad de Zaragoza (orcid)0000-0002-0719-7198 Delgado, Carmen Universidad de Zaragoza (orcid)0000-0002-8682-745X Gallego, José Ramón Universidad de Zaragoza (orcid)0000-0002-8298-4300 Canales, María Universidad de Zaragoza 5008 560 Universidad de Zaragoza Dpto.
