In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

Soil sickness is a critical problem for eggplant (Solanum melongena L.) under continuous cropping that affects sustainable eggplant production. Relay intercropping is a significant technique on promoting soil quality, improving eco-environment, and raising output. Field experiments were conducted from September 2010 to November 2012 in northwest China to determine the effects of relay intercrop...

Co-operative communication using relays can achieve spatial diversity, which improves the link quality in a wireless network. In this paper, the performance of an infrastructure based multi-antenna adaptive decode-and-forward cooperative relay network in presence of a m-Nakagami fading channel using Low Density Parity check (LDPC) code has been investigated. The bit error probability (BER) and ...

Cooperative diversity systems have received significant attention recently as a distributed means of exploiting the inherent spatial diversity of wireless networks. In this paper, we consider a cooperative diversity system consisting of a source, a destination, and multiple single–hop amplify–and–forward relays, and provide a mathematical framework for the asymptotic analysis of this system in ...

 Protective relays work in concert with sensing and control devices to accomplish their function. Under normal power system operation, a protective relay remains idle and serves no active function. But when fault or undesirable condition arrives Relay must be operated and function correctly.  A Power System consists of various electrical components like Generator, transformers, transmission l...

Heterogeneous cellular networks (HCNs) will be the typical network structure for future mobile networks. Relay nodes (RNs), as one type of low power nodes in the HCNs, can be deployed to increase cell coverage and improve cell-edge user throughput. Since RNs may be densely deployed in hot traffic zones, the co-channel interference (CCI) is more serious and complex than that in the conventional ...

Co-operative communication with relay assistance helps in enhancing the capacity of point to point links. The capacity of relay networks has been known to be upper bounded by the cut-set bound. Recently, the authors of [1] showed that it is possible to achieve the upper bound up to a constant additive gap, independent of the channel parameters. Presence of multiple relays provides multiple path...

The superficial layers of primate striate cortex (V1) contain a regular pattern of dense staining for cytochrome oxidase (CO) reactivity ("blobs") that receive direct input from the koniocellular layers of the lateral geniculate nucleus. It has been suggested that the blob regions are dedicated to processing color information. Here, the neurochemical compartmentalization of blobs and their inpu...

Due to practical demands, usability in security systems is reconsidered by researchers in recent years. Given the three prevailing short range communication technologies Radio Frequency Identification (RFID), Near Field Communication (NFC) and Bluetooth, Zero-Interaction Authentication (ZIA) is proposed for a subset of their application scenarios. Nevertheless, relay attacks especially ”ghost-a...
