In this paper, our previous work of Load-Based Power Saving (LBPS) for energy saving at the user side is extended to support integrated sleep scheduling for BS, RS, and MSS in the IEEE 802.16j Multi-Hop Relay Network. Topology-dependent time frame structure is adopted in our design to reduce the transmission delay in the relay network, and two LBPS schemes, namely LBPS-Aggr-MR and LBPS-Merge-MR...

The idea behind today’s power management is to reduce the power usage of systems when someone walks away from their PC or stops using after a period of time, by sending the hardware into a “sleep mode” or “power-saving mode”. Hardware components such as processors, memory chips and disks have advanced power management techniques (besides “power-saving” modes) to consume less power. However, ope...

This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed.  Several Strategies have been presented for supplying residential load (electrical and thermal loads...
