This paper revisits the problem of Traffic Engineering (TE) to evaluate the performance improvements achieved by destination-based TE when OSPF routing is fine-tuned to achieve route optimisation. We build upon the framework provided by evolutionary algorithms to present a TE model where link weights are computed by a genetic algorithm and used as fine-tuning parameters in destination-based pat...

Based on the popularity of mobile information and important role in marketing, use to publish travel advertisements has become a new choice for operators, which can also attract sports fitness people. This article studies influence official microblog tourist destination tourists’ destination. In this study, five factors, such as usefulness microblog, are taken independent variables, selection d...

To be trustworthy is an important characteristic of the next generation Internet. The routing system of the present Internet forwards packets only according to the destination IP address. Forged packets with spoofed source IP address will also be forwarded to the destination, which impairs the security of receiver and conceals the real identity of the sender. The trustworthy Internet requires t...

Node selection is a simple technique to achieve diversity and thereby enhance the physical layer security in future wireless communication systems which require low complexity. High-speed data transmission often encounters frequency selective fading. In this context, we evaluate exact closed-form expression for ergodic secrecy rate (ESR) of optimal source-destination pair scheme with single-car...

This paper studies two-hop cooperative demodulate-and-forward relaying using multiple relays in wireless networks. A threshold based relay selection scheme is considered, in which the reliable relays are determined by comparing source-relay SNR to a threshold, and one of the reliable relays is selected by the destination based on relay-destination SNR. The exact bit error rate of this scheme is...

In this study, we examined origin, destination, and community effects on first- and second-generation immigrants' health in Europe. We used information from the European Social Surveys (2002–2008) on 19,210 immigrants from 123 countries of origin, living in 31 European countries. Cross-classified multilevel regression analyses reveal that political suppression in the origin country and living i...

What drives export quality? Using firm-level data from Portugal on exports by product and destination market, we find that free-on-board unit values increase systematically with distance, and tend to be higher in shipments to richer nations. These relationships reflect not only the selection of firms across markets, but also the within-firm selection of product varieties across destinations. Fu...
