6 Proximal IoT Technologies in IoT with a focus on proximal functionality Targeting mostly smart home / building automation / proximal network Simplify connecting things in proximity (e.g. in building), monitor, control, automate, less focus on cloud or hierarchical structures Enablers: Discovery, Advertisement, Introspection, On-Boarding Need for multi-cast techniques to implement discovery & advertisement A user is still in the center of this proximal paradigm (onboarding, usage) Examples OCF (OIC, AllJoyn) with Open Source, Specifications Several proprietary or open Home Automation technologies Industrial space: OPC-UA (client/server), DDS (bus) 20-Sep rd onem2m Industry Day hosted by TSDSI 6

7 Distal IoT Technologies in IoT with a focus on distal functionality Targeting larger scale deployments of M2M/IoT devices in an overlay network Hiding complexity of network usage / routing / access control / sharing etc Storing & sharing of data in distributed, hierarchical topology Enablers: Proven security, access control, selective communications, addressing Agnostic to underlying NW technology, Desirable: Utilize optimizations for M2M / IoT, better efficiency in WAN usage Examples onem2m (open partnership of SDOs), specification openly available Cloud components of proprietary or open Home Automation technologies Proprietary platforms 20-Sep rd onem2m Industry Day hosted by TSDSI 7

8 Common Issues in Proximal IoT Focus on tying things in a proximal network together so that a user/controller can interact or control them, use rule engines etc. More human user and home centric (consumer space) or production floor centric (industrial space) No built-in functionality to drive communication based on policies regarding WAN selectivity / scheduling / event categorization No direct interactions between multiple proximal islands No concepts for overlaying a middleware over multiple proximal networks Might need to interact between a very large number of distributed islands No large scale device management integration Difficult to scale to larger deployments, private clouds etc. 20-Sep rd onem2m Industry Day hosted by TSDSI 8

9 Synergies of Proximal and Distal IoT Functionality to drive communication based on policies regarding WAN selectivity / scheduling / event categorization Addressing of things across many different locations / areas Supporting a hierarchically organized overlay network that transports messages to/from the right things Data and function sharing across different domains Support of interactions between multiple proximal islands Integration of proven large scale device management technologies Robust security functions (authentication, authorization, access control, encryption) 20-Sep rd onem2m Industry Day hosted by TSDSI 9

10 Jungle of Technologies, Standards, Consortia, OSS Projects Which groups actually specify technology, which are just doing marketing & promotion? Which technologies are used / will be used in M2M/IoT? Which technologies are overlapping or complementing each other?
