Optical networks-on-chip (ONoCs) have shown the potential to be substituted for electronic networks-on-chip (NoCs) to bring substantially higher bandwidth and more efficient power consumption in both onand off-chip communication. However, basic optical devices, which are the key components in constructing ONoCs, experience inevitable crosstalk noise and power loss; the crosstalk noise from the basic devices […]
Read moreThe current evolution of system architectures leads towards implementation of large number of processor cores into the same circuit. This evolution actually supports the performance increase and provides the capability to support the execution of very complex applications. Nevertheless, if these new architectures propose high computational performances, an important bottleneck appears for the communications between […]
Read moreDelay- and Disruption Tolerant Networks (DTNs) are based on an overlay protocol and on the store-carry-forward paradigm. In practice, each DTN node can store information for a long time before forwarding it. DTNs are particularly suited to cope with the challenges imposed by the space environment. This paper is focused on routing in space DTNs, […]
Read moreRecently, most wireless network security schemes merely based on physical layer characteristics tackle the two fundamental issues-device authentication and secret key extraction separately. It remains an open problem to simultaneously achieve device authentication and fast secret key extraction merely using wireless physical layer characteristics, without the help of advanced hardware or out-of-band channel. In this […]

Multi-relay Selection in Decode-and-Forward Cooperative Network Based on Genetic Algorithm
A novel multi-relay selection algorithm based on genetic algorithm (GA) in dual-hop decode- and-forward cooperative network is presented. The quality of service is expressed by the condition that the SNR of destination should be larger than 22R — 1 according to Shannon information capacity, in which R is its data-rate requirement. Moreover, residual energy status […]
