The energy management system operates the various energy manufacturing and energy usage components of the plant to minimize the cost of energy over time, or at various different times, while still meeting certain constraints or requirements within the operational system, such as producing a certain amount of heat or cooling, a certain power level, a certain level of production, etc. In some cases, the energy management system may cause the operational equipment of the plant to produce unneeded energy that can be stored until a later time and then used, or that can be sold back to a public utility, for example, so as to reduce the overall cost of energy within the plant.

An ad hoc network organizes itself to provide communications without need for an a priori designated central control mechanism or base stations. Such self-organization is challenging in a multihop ad hoc network having member nodes that are highly mobile and widely distributed. A Synchronous Collision Resolution (SCR) protocol and a Node State Routing (NSR) protocol are well suited to provide efficient ad hoc network organization. SCR is an access protocol that achieves high capacity collision free access using a signaling approach that creates a random cellular-like network after each signaling period. NSR is a routing protocol that uses the dissemination of node states to predict link availability and to assign metrics to those links for the creation of optimized routes. In use, the present invention provides quality of service and supports energy conservation for the mobile nodes.
