9. It is One backbone net for multiple hetero sub-net. Appliances are managed uniformly by the interoperability center. Variety of appliance access can be achieved through the center Appliances in different sub-networks would communicate and cooperate Appliances can access other sub-networks Here, ACCESS can be monitor, control, data exchange, or data sharing

14. MoHoNet –Middleware over Heterogeneous home Networks

15. Key Layers in MoHoNet AL - Adapter Layer –an adapter for each sub-network –Mapping the differentiation of sub-networks to CL CL - Core Layer –Centrally manage all appliances in a uniformed way by communication media independent –Store all appliance info in a unified data structure ASL - Application Support Layer –Basic Homenet application classes Security Management –Guarantee the safety of appliance access

17. Addressing – OnlineDeviceList one entry for every online appliance Standard entry format for appliances with connection information Centrally stored in Residential Gateway Synchronized with underlying hetero. Sub- networks through AL (Adapters for sub-net) Utilized by upper ASL depending on application classification Appliance connecting is completely transparent to ASL

19. Transport: CL–AL Service Interfaces Interfaces between CL and AL AL Service Interface: –Implemented by each HM Adapter –Used by CL to uniformly manage hetero. subnet appliances CL Service Interface: –Implemented in CL –Used by adapters

20. Application models: ASL General: –Generic services Controller: –Lighting control, heating control, environmental control, domestic appliances, etc. Appliance Mgmt: –Online and manageable appliance management Running Mgmt: –management and monitoring of utilities, security subsystem, etc. A/V Transfer: –Distribution and consumption of A/V content Data Transfer: –Communication

27. Summary Two kinds of Appliances : –MCA: inherit original connecting way No need to change for interoperating Majority of appliances –CA: need extra software to cooperate with other subnet through gateway Upgrade from MCA with adding special features Classes of features include: controller, data exchanger, etc MoHoNet –AL: Application by heterogeneity of sub-net independent –CL: Abstract the common aspects of all appliances –ASL: Support different application classes directly SG: Subnet Gateway MCA: Monitored/Controlled Appliance CA: Controlling Appliance

28. Summary (continued) Home network technologies are subnets being uniformly managed and scheduled by MoHoNet Subnet Interoperation is implemented as MoHoNet software Generally, only subnet gateway needs to be software upgraded, no change to subnet appliances Subnet appliance can choose to interoperate with other subnet appliances.

29. Future work Interoperations between other protocols etc. to check the implementation of these protocols. Join more of the 18012-2 project to check the implementation applications. We would like to have more communication for the work of 18012-3, like the outlines of 18012-3. We hope our work can be part of 18012-3 in the future. Enlarge commercialization work
