This paper investigates the outage probability of an energy harvesting (EH) relay-aided cooperative network, where a source node transmits information to its destination node with the help of an energy harvesting cooperative node. For such a system, we derive an explicit closed-form expression of outage probability over Nakagami-m fading channels for both amplify-and-forward (AF) and decode-and-forward...
This paper investigates the outage performance of an energy-harvesting(EH) relay-aided cooperative network, where the source node transmits information to its destination node with the help of multiple energy-harvesting cooperative nodes. For such a system, we derive an explicit closed-form expression of outage probability over Nakagami-m fading channels, where the on-off EH model is considered. We...
This paper investigates the effects of moving speed on handover performances with measurement data from three scenarios, i.e., viaduct environment, cutting environment and urban area. To do so, we first extract some samples from measurement data. As the data neglected the effect of shadow fading and interchannel interference (ICI), we then add some values into the data, which are the shadowing generated...
Some 2-D and 3-D graphical representation of DNA sequences have been given by Nandy, Leong and Mogenthaler, and Randic et al., which give visual characterizations of DNA sequences, and a number of different approaches have been developed to date on numerically characterizing DNA sequences, but application of such method to practical problems still remains a formidable task. In this paper, we presented...
Currently more and more people are suffering from ever-increasing unexpected e-mails (named spam), as well as the virus and worms introduced by spam. A lot of researchers and studies have focused on spam filtering. In this paper, we firstly present a new anti-spam technique, which include a users' active feedback mechanism, and Maximum entropy based spam filtering approach. Secondly we propose a prototype...
Phishing is a form of online identity theft. Phishers use social engineering to steal victims' personal identity data and financial account credentials. Social engineering schemes use spoofed e-mails to lure unsuspecting victims into counterfeit Websites designed to trick recipients into divulging financial data such as credit card numbers, account usernames, passwords and social security numbers...
Based on attributes permutation, an algorithm of Webpage information hiding is proposed, which overcomes the shortcoming of poor imperceptibility of Webpage algorithms currently in use, and improves the hiding capacity of the Webpage algorithm based on the order of attributes pair. The message , which is embedded into the Webpage, is firstly changed to a large number , and then hidden in the Webpage...
Secret messages can be embedded into letters in tags of a Webpage in ways that are imperceptible to the human eye viewed with a browser. These messages, however, alter the inherent characteristic of the offset of a tag. This paper presents a new higher-order statistical steganalytic algorithm for detection of secret messages embedded in a Webpage. The offset is used to build the higher-order statistical...
