Sensors react with no communications. • Resource Initiated – DR polls a site/bulletin board for what information is desired. • Bulk Dispatched – System operator sends broad message to DR and DR responds. • Precision Dispatch – Full bi-directional communications. Integrate what is going on at DR and then decisions are made on what performance of DR is desired.
