Basic Concepts One backbone homenet for multiple heterogeneou

s sub-networks Hetero. networks should be managed and used un

iformly Appliances in different sub-networks would comm

unicate and cooperate Two sub-classes of class 1 HES appliances

• MCA - Monitored or Controlled Appliances• CA – Controlling Appliances, may communicate with ap

pliances in other sub-networks, such as: unified intelligent controller, communication bridge, etc.

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

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 c

ommunication 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 u

nified form From CL to AL:

• Interface name: ActionToAdapters• Methods: getDeviceList(), getDeviceStat(), doAct

ion(), 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

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;


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


• A complete set of home network system •STB • Visual talker

•“Wireless” water heater

• SMS air conditioner• Networked wine cellar

• World’s first UWB wireless network HDTV

• Home entertainment center


Commercialization and Products with ItopHome

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.


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.
