Applications do not have direct accessibility to devices Chaining or interoperation with gateways and application controller. Present, But does not have any interfaces Device /sensors are addressable. Present. Three interfaces – I1, I2, I3 – device to device interface is out of scope I2 ->B5: application server -> smart device I2  B1. application - intermediate node. I2->B5,B1->mid ETSITwo domains : Network Domain (includes access, core, & M2M service capability), Device and Gateway Domain NAPresent (Direct Connectivity from application to device as well as device to device). The M2M Device performs the procedures such as registration, authentication, authorization, management and provisioning with the Network Domain Three interfaces – mia,mid,dia device to device interfaces are also considered TIATwo domains : Device & application. Application directly access device gateway & devices Chaining of intermediate nodes. B6,B7 are defined reference points Present -Direct Device Interaction. Uses standardized set of verbs applied to a specific device like Set, Get. Device to device interaction is also possible Intermediate nodes/gateways to gateways interfaces are considered GISFI # 07, Dec 19-22, 2011, New Delhi

Three interfaces – I1, I2, I3 – device to device interface is out of scope 3GPP3 different types of communications NAAlternative addressing solution based on IP addresses. Nodes are addressable MTC devices communicating with the MTC server through API. (within the access network). MTC server connects to IoT stack through I1 (functionality need to be understood) MTC device supporting directly Internet, can connect to I2 GISFI # 07, Dec 19-22, 2011, New Delhi

12 12 Conclusion: TCS Proposed IoT Architecture in GISFI GISFI # 07, Dec 19-22, 2011, New Delhi I1 Signifies a family of interfaces including the 3 rd party network accessibility. Device to device connectivity and interfaces are not considered. I2 Signifies the interfaces for application middleware/ application to devices directly, as well as application middleware to access gateway. Devices are considered addressable. Internet is considered as Backbone network. Chaining among application middleware nodes as well as access gateways are considered. No interfaces are defined for this. No use case is mapped yet. Chaining of application middleware may suitable for distributed computing. I3 (APIs) Interface exposed from application middleware to Application does not exist in ETSI & TIA
