8 M2M Device Domain M2M Device – A device that runs application(s) using M2M capabilities and network domain functions. An M2M Device is either connected straight to an Access Network or interfaced to M2M Gateways via an M2M Area Network. M2M Area Network – A M2M Area Network provides connectivity between M2M Devices and M2M Gateways. Examples of M2M Area Networks include: Personal Area Network technologies such as IEEE , SRD, UWB, Zigbee, Bluetooth, etc or local networks such as PLC, M-BUS, Wireless M-BUS. M2M Gateways – Equipments using M2M Capabilities to ensure M2M Devices interworking and interconnection to the Network and Application Domain. The M2M Gateway may also run M2M applications.

9 M2M Network/App Domain Network Service Capabilities – Provide functions that are shared by different applications – Expose functionalities through a set of open interfaces – Use Core Network functionalities and simplify and optimize applications development and deployment whilst hiding network specificities to applications – Examples include: data storage and aggregation, unicast and multicast message delivery, etc. M2M Applications (Server) – Applications that run the service logic and use service capabilities accessible via open interfaces.

10 M2M Market Characteristics Initial investment is difficult (e.g., license fees) Complex supply chain: from chipset to network to mobile operators Long-tail business Low ARPU (<$10) compared to voice (<$30) Lagging standards

11 M2M Standard Trends So far heterogeneous M2M devices/platforms – SKT/KT/LG M2M platforms – Orange M2M Connect – Nokia M2M Gateway – Sprint Business Mobility Framework M2M standard activities for interoperability – Access networks: UMTS/GSM (3GPP, ETSI), CDMA (3GPP2), WiFi/WiMAX/ZigBee (IEEE) – App and middleware: TIA TR-50.1 Smart Device Communications (SDC), ESTI TC M2M

12 M2M Standard Areas ETSI formed a TC to focus on describing the scenarios of applications: – Smart Grid/Smart Meters – eHealth – Automotive Applications – City Automations – Connected Consumers 3GPP work is under the name of Machine Type Communications (MTC) 3GPP2 (and CDG) has just started looking into the potential impacts * : TIA TR-50.1

13 ETSI M2M Standards M2M Service Requirements (Draft: ETSI TS V0.5.1, Jan. 2010) – General requirements on M2M communications ranging from Device initiation, authentication, to noninterference of electro-medical devices. – Managements: fault handling, configuration, accounting – Functional requirements: data collection and reporting, remote control, QoS support, etc. – Security: authentication, authorization, data integrity, trust management – Naming/numbering/addressing: IP, URL, SIP M2M Functional Architecture (Draft ETSI TS V0.1.2, Jan. 2010)

14 ETSI M2M Standards M2M apps under development including: – Smart Meters Draft ETSI TR V0.3.2, Jan – eHealth Draft ETSI TR V0.2.1, Sep – Connected Consumers Draft ETSI TR V0.0.1, Dec – City Automation Draft ETSI TR V0.0.2, Jan – Automotive Apps Draft ETSI TR V0.1.0, Jan – Car Charging, Fleet Management, Anti-Theft

15 3GPPs M2M Standards System Improvement for Machine Type Communications (MTC) (3GPP TR V0.21, Jan. 2010, Release 10) Heavy discussions in SA1 and the doc listed 11 issues: – Group based optimization, – TC Devices communicating with one or multiple servers, – Device communicated with each other, – Online, off-line small data transmissions, – Low mobility, – MTC subscriptions, – Device trigger, time control, – MTC monitoring and decoupling MTC server from 3GPP architecture.

19 Evolution of the Web Web of pages - text, manually created links - extensive navigation Web of databases - dynamically generated pages - web query interfaces Web of resources - data = service = data, mashups - ubiquitous computing Web of people - social networks, user-created casual content - Twine, GeneRIF, Connotea Web as an oracle / assistant / partner - ask the Web: using semantics to leverage text + data + services - Powerset

20 Semantic Web: Key Components Ontology: Agreement with a common vocabulary/nomenclature, conceptual models and domain Knowledge Schema + Knowledge base Agreement is what enables interoperability Formal description - Machine processability is what leads to automation

21 Semantic Web: Key Components Semantic Annotation (Metadata Extraction): Associating meaning with data, or labeling data so it is more meaningful to the system and people. Can be manual, semi-automatic (automatic with human verification), automatic.

22 Semantic Web: Key Components Reasoning/Computation: semantics enabled search, integration, answering complex queries, connections and analyses (paths, sub graphs), pattern finding, mining, hypothesis validation, discovery, visualization

23 SW Stack: Architecture, Standards

24 From Syntax to Semantics Shallow semantics Deep semantics Expressiveness, Reasoning

25 a little bit about ontologies

26 Open Biomedical Ontologies Open Biomedical Ontologies, Many Ontologies Available Today

Create/extract as much (semantics) metadata automatically as possible; Use ontlogies to improve and enhance extraction Extraction for Metadata Creation

30 Web 2.0 Man Meets Machine

31 Putting the man back in Semantics Web 2.0 is made of people (Ross Mayfield) Web 2.0 is about systems that harness collective intelligence. (Tim OReilly) Semantic Web focuses on artificial agents The relationship web combines the skills of humans and machines

34 Events – Spatial, Temporal and Thematic Spatial Temporal Thematic

35 Events and STT Dimensions Powerful mechanism to integrate content – Describes Real-World occurrences – Can have video, images, text, audio (same event) – Search and Index based on events and STT relations Many relationship types – Spatial: What events happened near this event? What entities/organizations are located nearby? – Temporal: What events happened before/after/during this event? – Thematic: What is happening? Who is involved? Going further Can we use: Who? Where? What? Why? When? How? Use integrated STT analysis to explore cause and effect

36 36 High-level Sensor Low-level Sensor How do we determine if the three images depict … the same time and same place? the same entity? a serious threat? Scenario: Sensor Data Fusion and Analysis

37 Raw Sensor (Phenomenological) Data Feature Metadata Entity Metadata Ontology Metadata Expressiveness Data (World) Information (Perception) Knowledge (Comprehension) Data Pyramid An object by itself is intensely uninteresting. – Grady Booch, Object Oriented Design with Applications, 1991 Keywords | Search (data) Entities | Integration (information) Relationships, Events | Analysis, Insight (knowledge)
