Connecting Smart Homes and Smart Grids to Save Energy: Home Area Networks

By Barry Haaser, Chairman of the Digital Home Alliance and Senior Director, LONWORKS Infrastructure Business, Echelon Corporation

Successful adoption of consumer products can be tied to ease-of-use and simplicity. The ANSI/CEA 709.1 and EN 14908 standards were recently enhanced to include provisions for self-installation of intelligent devices in the HAN and automatic discovery by in-home displays and consumer products. The CECED (European Committee of Domestic Equipment Manufacturers) created a standard for networking consumer appliances together in a home based on the ANSI/CEA and EN standards. The result of this work appears in the innovative Interoperable Self Installation (ISI) technology to support self installation of consumer’s products.

The ISI protocol is an application-layer protocol that allows installation of devices and connection management without the use of a separate network management tool. The ISI protocol can be used with small networks with up to 200 devices. The ISI protocol supports transitioning to a larger managed network utilizing a network management tool for configuration of all devices in the network. A network management tool provides additional flexibility, enables more complex connections and configuration, and supports larger networks. The ISI protocol simplifies installation by eliminating the need for a separate tool for simple networks.

In an ISI network, there is no central network management server, so each device must allocate its own network resources and automatically resolve any conflicts that may occur due to duplicate resource assignment.
