A Key Renewal Scheme under the Power Consumption for Wireless Sensor Networks
Chien Lung Wang, Tzung-Pei Hong, Gwoboa Horng, Wen-Hung Wang
In this paper, we propose a distributed, reliable and low-power-consumed key-renewal scheme for wireless sensor networks. The proposed scheme is divided into parts: the server part and the sensor-node part. The server will produce an appropriate key-generation function (KGF) for key renewal on sensor...

Incorporating Value-at-Risk in Portfolio Selection: An Evolutionary Approach
Chueh-Yung Tsao, Chao-Kung Liu
The mean-variance framework for portfolio selection should be revised when investor’s concern is the downside risk. This is especially true when the asset returns are not normal. In this paper, we incorporate value-at-risk (VaR) in portfolio selection and the mean-VaR framework is proposed. Due to the...
