Abstract

Disclosed is a Network Energy Protocol (NEP) to be implemented through a network mechanism which broadcasts Energy Consumption Advisories (ECAs) that devices can follow. With this protocol, instead of largely static rules governing power consumption, devices can autonomically adjust their energy usage based upon the real time state of available electricity. Power availability can be affected by such things as brown outs, energy action days, natural disasters or any other power disruptions. Every device that recognizes this protocol can take action even when there is otherwise no obvious reason to do so, such as dimming a laptop Liquid Crystal Display (LCD) display during an energy action day when the laptop hasn't been removed from its docking station.

System and Methodology for Realtime Energy Status Broadcast

Efficient use of energy is of increasing importance in today's world. Most of today's devices run at only two power levels, on and off. While attention has been given to reducing the energy consumption of individual devices, there has been less focus on monitoring, conveying, and reacting to fluctuating energy demands and available supply. While many electronic devices, most notably computers, have various energy saving capabilities, utilizing these capabilities requires largely static rules and static power profiles. As an example of these static rules, a laptop removed from a docking station's AC power will lower the Liquid Crystal Display (LCD) brightness to 50%. In order for devices to make more intelligent and efficient energy consumption decisions, and to do so quickly, an energy protocol should be established which dynamically provides Energy Consumption Advisories (ECAs) to all devices in the affected region.

The Network Energy Protocol (NEP) allows an energy state level to be defined by the Network Energy Protocol (NEP) server, the energy state level dictates the availability of electricity in the local area. The NEP is transport agnostic, but could be implemented over traditional Transmission Control Protocol / Internet Protocol (TCP/IP) or User Datagram Protocol (UDP) based networks utilizing a request/response polling method, over the air, or using X10 protocol. The protocol will include the aforementioned ECA which is an enumerated value representing current energy status such as energy action days, brown outs, fluctuating energy costs or business as usual. If energy should be conserved, the ECA will communicate this to interested devices. If energy is abundant the E...
