MoHoNet –Middleware over Heterogeneous hOme Networks Implementation of Interoperability

Typical Home Networks Backbone Appliances SG: Subnet Gateway Backbone Gateway SG1 SG2 SGn Homenet Backbone Subnet-1 Subnet-2 Subnet-n Internet

Basic Concepts  One backbone homenet for multiple heterogeneous sub-networks  Hetero. networks should be managed and used uniformly  Appliances in different sub-networks would communicate and cooperate  Two sub-classes of class 1 HES appliances MCA - Monitored or Controlled Appliances CA – Controlling Appliances, may communicate with appliances in other sub-networks, such as: unified intelligent controller, communication bridge, etc.

Our Ideas Backbone Appliances SG: Subnet Gateway Backbone Gateway SG1 SG2 SGn Homenet Backbone Subnet-1 Subnet-2 Subnet-n Internet Middleware HM Adapters HM Center

Goal  All appliances can be managed by a center  Variety of appliance access can be achieved through the center  Appliances can access other sub-networks  Here, ACCESS can be monitor, control, data exchange, or data sharing

MoHonet Architecture

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

Standard Adapter Service Interface  Defined between CL and AL  Manage heterogeneous sub-networks in an unified form  From CL to AL: Interface name: ActionToAdapters Methods: getDeviceList(), getDeviceStat(), doAction(), etc  From AL to CL: Interface name: ReportToCore Methods: deviceReport(), etc

Key database – OnlineDeviceList  one entry for every online appliance  Standard entry format for appliances with connection information  Usually 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 way is totally transparent for ASL

Basic Application classes  Controller  MeterReader  MediaStreamer  DataNetwork

Centralized Applications Backbone Appliances SG: Subnet Gateway MCA: Monitored/Controlled Appliance Backbone Gateway SG1 SG2 SGn Subnet-1 Subnet-n InternetHomenet Middleware MCA11 MCA1m MCA21 MCA2x Subnet-2 MCAn1 MCAnz

Centralized Applications  Remote Web Control - Controller Control appliances through web browser  Remote Phone Control - Controller Control appliances through phone call  Backbone Unified Controller - Controller One controller can control all appliances  Remote Household Video Monitoring  Data Network  Media Center  ……

CA2 Applications for different Sub-net Backbone Appliances Backbone Gateway SG1 SG2 SGn Subnet-1 Subnet-2 Subnet-n InternetHomenet Middleware MCAn1MCAnz SG: Subnet Gateway MCA: Monitored/Controlled Appliance CA: Controlling Appliance CA1MCA21MCA2m BlueBlock: extra software added

Summary  Two kinds of Appliances : MCA: inherit original connecting way  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

Standardization promotion  Two special frequencies bands, 430MHz~432MHz and 779MHZ~787MHz, were allocated by State Radio Regulatory Commission of China to deal with wireless interconnection among networking equipments;  China’s networking working group was founded in 2001 under authorization from MII (Ministry of Information Industry) of China;  In June 2005, was approved to be the national industry standards on home networking; ISO/IEC JTC1 N Sept, 2006

 About ITopHome Alliance: In July,2004, China Home Network Standard Industrialization Alliance, named as ITopHome, was founded by the leading companies of Home Network technologies. The industries that alliance members engaged in include consumer electronics, home appliances, computing networking, home automation, home security, computing network, mobile products and other application. Current members are more than 200 companies ISO/IEC JTC1 N Sept, 2006

 From 2005, all the home appliances produced by Haier are installed with the communication modules supporting ITOPHOME standards. This covers the industry revenue as 1 billion per year.  Over 100 different companies supporting ItopHome, with which there hundreds products  Products supporting ITOPHOME standards selling of 50 million in 2005  In 2006, it is estimated that there will be more than 200,000 homes install the home network and until 2008, the number will be several millions. ISO/IEC JTC1 N Sept, 2006

 Based on all the features of ITOPHOME, we really hope it becomes a NP in 10, Oct, and be an international standard in the future. THANK YOU Dr. WANGGANG China Home Network Standard Group ISO/IEC JTC1 N Sept, 2006
