14 Data-aware or information-centric networking Technology for efficient handling of massive IoT data Integration of huge number of heterogeneous devices Trust contained in data Related work ITU-T Y /21

15 Mobile Edge Computing Provisioning in-network processing (together with required data) functions closer to end user devices Mobile cloud Reduces service response latency e.g. automated driving Reduces data volume transaction Lightens end user device functionality Enabling economically and technologically massive deployment 15/21

16 New naming and identification scheme IDs assigned to various things devices, data or content, users, services, and others (e.g. application software, storage or computing resources) Mapped to underlying heterogeneous network locations Devices ID based control (security/privacy) ID selection Data Heterogeneous ID namespace Users Services ID allocation & revocation ID discovery/authentication ID-to-location mapping Others ID registration Multi-domain ID resolution systems Internet (IPv4, IPv6) Cellular networks (2G,3G,4G,5G), PSTN Related work ITU-T Y.3031 Location of things in heterogeneous networks Ethernet, WiFi, ZigBee, Bluetooth, etc. 16/21

17 ID-based communication Interconnecting heterogeneous devices and communication technologies Location-independent communication Related work: ITU-T Y.3032, 3034 Each host is assigned with a hostname and ID ID mh#himalis.net Name Resolution e.g. IPv4 IPv4 IPv6 Peer authentication before starting data communication ch#nict.go.jp a01-be--100 ID-based communication Locators Multihoming Gateway (GW) Upper layers Network layer Network protocol translation GW ID Locators 2001:db8:: :5a:efd::2 17/21

18 Trust, security, privacy Five dimensions of trust: availability, reliability, performance, security, privacy Three domains in IoT trust: 1. Platform Generic and service specific functionality e.g., hiding identity in private/personal data 2. Network Encrypted pipe Location privacy 3. Storage or cloud Several issues as discussed in previous sessions 18/21
