In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP). As yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...

ABSTRACT Recently, for energy saving in wireless sensor networks, the data aggregation technique has been proposed. In this paper, we discuss the trade off between communication delay and energy consumption of the technique. At first, we analyze the full aggregation compared with nonaggregation with Markovian chain and simulation. The result shows that non-aggregation method suffers large energ...

This paper presents a variable frame rate (VFR) analysis method that uses an a posteriori signal-to-noise ratio (SNR) weighted energy distance for frame selection. The novelty of the method consists in the use of energy distance (instead of cepstral distance) to make it computationally efficient and the use of SNR weighting to emphasize the reliable regions in speech signals. The VFR method is ...

This paper presents an energy-efficient loadbalancing algorithm for Wireless Sensor Networks. The algorithm specifies that only the nodes which have residual energy above a threshold can take part in routing, and that residual energy is to be updated at the highest opportunistic rate supported by the network. The algorithm was tested on and showed improvements to hierarchical data aggregation a...

This paper investigates the system achievable rate and optimization for the multiple-input multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) system with an energy harvesting (EH) relay. Firstly we propose a time switchingbased relaying (TSR) protocol to enable the simultaneous information processing and energy harvesting at the relay. Then, we discuss its achievable rate ...
