The main objective of this event is twofold. First, the conference aims at dissemi- nating recent research advancements, offering researchers the opportunity to present their novel resultsabout thedevelopment, deployment, anduse ofICT insmartcities. A second goal is to promote sharing of ideas, partnerships, and cooperation between everyone involved in shaping the smart city evolution, thus contributing to routing technical challenges and their impact on the socio-technical smart cities system. The core mission of the conference is to address key topics on ICT infrastructure (technologies, models, frameworks) and services in cities and smart communities, in order to enhance performance and well-being, to reduce costs and resource con- sumption, and to engage more effectively and actively with their citizens. The technical program of the conference covers a broad range of hot topics, spanning over five main tracks: e-health and smart living, privacy and security, smart transportation, smart industry, and infrastructures for smart cities. The program this year also included: (cid:129) A special session about challenges and opportunities in smart cities, which cut across and beyond the single field of interests, such as socio-technical challenges related to the impact of technology and smart cities evolution. (cid:129) A showcase, which represents the other pulsing soul of the conference: a place where industrial partners, public stakeholders, scientific communities from the pan-European area can share their experiences, projects and developed resources. We hope to provide a good context for exchanging ideas, challenges, and needs, gainingfrom theexperiences andachievements oftheparticipantsandcreatingthe proper background for future collaborations.

The second edition of EAI IISSC attracted 23 manuscripts from all around the world. At least two Technical Program Committee (TPC) members were assigned to revieweachpaper.Eachsubmissionwentthrougharigorouspeer-reviewprocess.The authors were then requested to consider the reviewers’ remarks in preparing the final versionoftheirpapers.Attheendoftheprocess,12paperssatisfyingtherequirements ofquality,novelty,andrelevancetotheconferencescopewereselectedforinclusionin VI Preface theconferenceproceedings(acceptancerate:52%).Threemorepaperswereinvitedby the TPC owing to the appropriateness of the presented topics. We are confident that researchers can find in the proceedings possible solutions to existingoremergingproblemsand,hopefully,ideasandinsightsforfurtheractivitiesin the relevant and wide research area of smart cities. Moreover, the best conference contribution award was assigned at the end of the conferencebyacommitteeappointedbytheTPCchairsbasedonpaperreviewscores. We would like to thank all the many persons who contributed to make this con- ference successful. First and foremost, we would like to express our gratitude to the authorsofthetechnicalpapers:IISSC2017wouldnothavebeenpossiblewithouttheir valuable contributions. SpecialthanksgotothemembersoftheOrganizingCommitteeandtothemembers of the Technical Program Committee for their diligent and hard work, especially to Eng. Marco Zappatore, who deserves a special mention for his constant dedication to the conference. We would like also to thank the keynote and invited speakers and the showcase participantsfortheirinvaluablecontributionandforsharingtheirvisionwithus.Also, we truly appreciated the perseverance and the hard work of the local organizing sec- retariat (SPAM Communication): Organizing a conference of this level is a task that canonlybeaccomplishedbythecollaborativeeffortofadedicatedandhighlycapable team. We are grateful for the support received from all the sponsors of the conference. Major support for the conference was provided by Capgemini Italia and University of Salento. In addition, we are grateful to the Municipality and the Province of Brindisi, the institutions,andthecitizensandentrepreneursofApuliaRegionforbeingclosetousin promoting and being part of this initiative. Last but not least, we would like to thank all of the participants for coming. September 2017 Antonella Longo Massimo Villari Daniele Napoleone Preface TheSecondInternationalConferenceonCloud,NetworkingforIoTsystems(CN4IoT) was held in Brindisi, Italy on April 20–21, 2017, as a co-located event of the Second EAI International Conference on ICT Infrastructures and Services for Smart Cities. ThemissionofCN4IoT2017wastoserveandpromoteongoingresearchactivities on the uniform management and operation related to software-defined infrastructures, in particular by analyzing limits and/or advantages in the exploitation of existing solutionsdevelopedforcloud,networking,andIoT.IoTcansignificantlybenefitfrom the integration with cloud computing and network infrastructures along with services providedbybigplayers(e.g.,Microsoft,Google,Apple,andAmazon)aswellassmall andmediumenterprisesalike.Indeed,networkingtechnologiesimplementbothvirtual and physical interconnections among cooperating entities and data centers, organizing them into a unique computing ecosystem. In such a connected ecosystem, IoT appli- cations can establish a elastic relationship driven by performance requirements (e.g., information availability, execution time, monetary budget, etc.) and constraints (e.g., input data size, input data streaming rate, number of end-users connecting to that application, output data size, etc.) The integration of IoT, networking, and cloud computing can then leverage the rising of new mash-up applications and services interacting with a multi-cloud ecosystem, where several cloud providers are interconnected through the network to deliver a universal decentralized computing environment to support IoT scenarios. ItwasourhonortohaveinvitedprominentandvaluableICTinternationalexpertsas keynote speakers. The conference program comprised technical papers selected throughpeerreviewsbytheTPCmembersandinvitedtalks.CN4IoT2017wouldnot be a reality without the help and dedication of our conference manager Erika Pokorna from the European Alliance for Innovation (EAI). We would like to thank the con- ferencecommitteesandthereviewersfortheirdedicatedandpassionatework.Noneof this would have happened without the support and curiosity of the authors who sent their papers to this second edition of CN4IoT.
