Online energy-efficient real-time task scheduling for a heterogeneous multicore system is complicated because of the synergistic processing between cores and trade-off between energy conservation and schedulability. This paper proposes a multicore energy efficiency ratio for minimizing energy consumption and a bandwidth reservation algorithm for improving quality of service for applications. The performance...
This paper presents a novel design of simplified, low cost and lightweight mode reconfigurable cubic patch antenna that is designated to operate around 2.4 GHz for the applications of GSSP, WLAN/Bluetooth/WiBree/ZigBee, LTE, DMB and wireless routers. When this antenna is unfolded, it radiates omni-directionally at 2.4 GHz with a bandwidth (S11< −10 dB) of 450 MHz (2.3 GHz–2.75 GHz); while when...
This paper presents a novel design of ultrawideband origami quasi-taper antenna that can be reconfigured to operate from 1.28 GHz to 4.12 GHz at 3 different states of height, and the operating bandwidths at the 3 states are respectively 1.28 GHz–1.64 GHz (25%), 1.64 GHz–3.56 GHz (74%) and 3.56 GHz–4.12 GHz (14.6%). Therefore, this antenna can be applied for kinds of wireless communications in L band...
Wireless power and data transfer (WPDT) through the strongly coupled magnetic resonance (SCMR) method at an RFID frequency is reported. The proposed system consists of four single resonant loops, in contrast to the two resonant loops traditionally used in RFID. The paper addresses SCMR high Q-factor and low bandwidth with a tradeoff to achieve high bandwidth for data transfer comparable to RFID.
