Open challenges of current IoT simulators and testbeds

  1. 1. PANEL – SESSION 4 TRIGGERING NEW DIGITAL MARKETS: ENVIRONMENTAL MONITORING, EHEALTH, SMART INDUSTRY AND MANUFACTURING, BUSINESS INTELLIGENCE AND EDUCATION WITH SCIENCE AND RESEARCH OPEN CHALLENGES OF CURRENT IOT SIMULATORS AND TESTBEDS PANELIST: JOSÉ MARCOS NOGUEIRA - UFMG
  2. 2. INTERNET OF THINGS ENABLING THE MACHINE PERCEPTION OF THE REAL WORLD AND SEAMLESS INTERACTION WITH IT
  3. 3. INTERNET OF THINGS A VERY LARGE NUMBER OF CONNECTED DEVICES ADDED TO THE INTERNET A MULTITUDE OF SENSORS AND MOBILE USERS’ TERMINALS DESIGNED TO INTERACT DEVICES WITH VERY SPECIFIC CHARACTERISTICS IN TERMS OF HARDWARE, SOFTWARE, AND MANAGEMENT
  4. 4. • MULTIDISCIPLINARY DOMAIN WITH MANY ISSUES • TECHNICAL: ROUTING, PROTOCOLS, SEMANTIC QUERIES ... • TECHNICAL/SOCIAL: SECURITY, PRIVACY, USABILITY ... • SOCIAL AND BUSINESS • APPLICATIONS: EQUALLY DIVERSE, THE EXISTING AND THE POTENTIAL • ENVIRONMENTAL AND PERSONAL HEALTH MONITORING • MONITORING AND CONTROL OF INDUSTRIAL PROCESS: AGRICULTURE, SMART SPACES, SMART CITIES ... INTERNET OF THINGS
  5. 5. IOT DESIGN/STUDY/PLANNING/SETUP THE DESIGN OR STUDY OR PLANNING OR SET UP OF COMPLEX IOT STRUCTURES REQUIRES APPROACHES OR TECHNIQUES EQUALLY COMPLEX EXPERIMENTATION <--> SIMULATION
  6. 6. CHALLENGES AND REQUIREMENTS üFROM INTRA-NET TO INTER-NET à PROBLEMS OF SCALE üINCREASING HETEROGENEITY OF DEVICES AND DEVICE TECHNOLOGIES à SUPPORT FOR INTEROPERABILITY AT DIFFERENT LAYERS üINCREASING HETEROGENEITY AND SCALE à REPEATABILITY OF EXPERIMENTS MORE DIFFICULT
  7. 7. CHALLENGES AND REQUIREMENTS üMULTIPLE APPLICATIONS DOMAINS à INCREASED CONCURRENCY OF ACCESS THE INFRA-STRUCTURE üREAL WORLD APPLICATIONS AND SERVICES à REALISM OF THE ENVIRONMENT FOR EXPERIMENTATION üMOBILITY üUSER INVOLVEMENT AND IMPACT
  8. 8. CHALLENGES AND REQUIREMENTS üMODELS TO REPRESENT THE DIVERSITY à CO-OPERATION, INTERACTION, INTEGRATION üARTIFICIAL ASSUMPTION ON RADIO PROPAGATION, TRAFFIC, FAILURES PATTERN, TOPOLOGIES, NATURE BEHAVIOR üSTRONG DEPENDENCY OF IOT SYSTEMS ON REAL-WORLD PROCESSES THAT ARE OFTEN A RESULT OF COMPLEX SYSTEMS-OF-SYSTEMS INTERACTIONS AND EXTREMALLY DIFFICULT TO MODEL ACCURATELY
  9. 9. CHALLENGES AND REQUIREMENTS üHOW TO MODEL HETEROGENOUS THINGS/DEVICES AND PUT THEM WORKING TOGETHER? WHAT IS THE INFLUENCE OF ONE MODEL OVER OTHER WHEN IN CONCURRENT OPERATION? üHOW TO TO SIMULATE HUGE NUMBER OF DEVICES WITH POSSIBLY MANY DIFFERENT TIME GRANULARITY? üPROBLEM OF SYNCHRONIZATION. üCAN WE DEVISE SIMULATORS THAT OPERATE AT DIFFERENT LEVELS OF ABSTRACTION AT THE SAME TIME? üMULTI-LEVEL SIMULATION
  10. 10. THE DESIGN OF COMPLEX IOT SETUPS REQUIRES THE SUPPORT OF LARGE SCALE TESTBEDS üEXPERIMENTATION WITH REAL DEVICES üINTERACTION WITH THE REAL ENVIRONMENT üFEDERATION OF TESTBEDS üORCHESTRATION OF THE EXPERIMENTS The usage of scalable simulation tools üNumber of nodes in the scenario üLevel of detail of interactions among nodes ükey elements for the scalability of the simulator
  11. 11. FOR TESTBEDS, SOME INITIATIVES • FED4FIRE - LARGEST FEDERATION WORLDWIDE OF NEXT GENERATION INTERNET (NGI) TESTBEDS (IOT AND MORE) • GENI - OPEN INFRASTRUCTURE FOR AT-SCALE NETWORKING AND DISTRIBUTED SYSTEMS RESEARCH AND EDUCATION • FUTEBOL PROJECT TESTBEDS - FEDERATION OF TESTBEDS FOR EXPERIMENTATION AT THE CONVERGENCE OF OPTICAL AND WIRELESS DOMAINS • GEFI 2018 (GLOBAL EXPERIMENTATION FOR FUTURE INTERNET WORKSHOP)
  12. 12. FOR SIMULATION • MAIN TECHNIQUES • DISCRETE EVENTS SIMULATION • AGENT-BASED SIMULATION • APPROACHES • CENTRALIZED AND PARALLEL • DISTRIBUTED à PARALLEL AND DISTRIBUTED SIMULATION (PADS) • SYNCHRONIZATION ISSUES • HYBRID DISCRETE EVENTS AND AGENT-BASED • MULTI-LEVEL SIMULATION à FINE AND COARSE GRAINED MODELS WORKING TOGETHER
  13. 13. THANK YOU!
