In this field, this paper introduces an optimization framework to perform the allocation of physical shared resources of wireless sensor networks to multiple requesting applications. The proposed optimization framework aims to maximize the total number of applications which can share a common physical network, while accounting for the distinguishing characteristics and limitations of the wireless sensor environment (limited storage, limited processing power, limited bandwidth, tight energy consumption requirements). Due to the complexity of the optimization problem, a heuristic algorithm is also proposed. The proposed framework is finally evaluated by simulation considering realistic parameters from actual sensor nodes and deployed applications to provide a detailed performance evaluation and to assess the gain involved in letting multiple applications share a common physical network with respect to one-application, one-network vertical design approaches. 000149009 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000149009 590__ $$a3.047$$b2016 000149009 591__ $$aCOMPUTER SCIENCE, INFORMATION SYSTEMS$$b33 / 146 = 0.226$$c2016$$dQ1$$eT1 000149009 591__ $$aTELECOMMUNICATIONS$$b24 / 88 = 0.273$$c2016$$dQ2$$eT1 000149009 592__ $$a0.648$$b2016 000149009 593__ $$aComputer Networks and Communications$$c2016$$dQ1 000149009 593__ $$aHardware and Architecture$$c2016$$dQ1 000149009 593__ $$aSoftware$$c2016$$dQ2 000149009 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000149009 700__ $$0(orcid)0000-0002-8682-745X$$aGállego, J.
