Cooperative networking plays an important role in wireless adhoc and sensor networks, in which the information from the source to the destination is relayed by intermediate nodes. In this paper, we propose OFDM-based all subcarrier and per subcarrier basis relay selection schemes. The relay selection is based on average signal to noise ratio (SNR) estimation. Data aided (DA) preamble based MMSE...

In this paper, we present a capacity analysis for broadband power line communication (PLC) channels, impaired by the Bernoulli–Gaussian impulsive noise, exploiting both orthogonal frequency division multiplexing (OFDM) and singlecarrier frequency-domain equalisation (SC-FDE) techniques. First, we investigate point-to-point communications and formulate the continuous signal model for OFDM and SC...

Relay-aided free-space optical (FSO) communication systems have the ability of mitigating adverse effects link disruption by dividing a long into several short links. In order to solve relay selection (RS) problem in decode and forward (DF) relay-aided FSO system, we model scheme as Markov decision process (MDP). Based on dueling deep Q-network (DQN), DQN-RS algorithm is proposed, which aims at...

Since their appearance, Programmable Logic Controllers (PLCs) have gain a very strong position in the industrial automation field. The growing complexity of the applications using this type of equipment strongly depends on programmers and maintenance personnel, and so more and better PLC education is of great demand nowadays. The present work deals with an object oriented simulator for the rela...

In this article, we investigate the use of half duplex time division relay protocols to possibly provide achievable rate improvements, power saving, and coverage extension in home power line communication (PLC) networks. We consider a network where the communication between the source and the destination nodes follows an opportunistic protocol, namely, the relay is used whenever it allows with ...

Link adaptive relaying (LAR) is one of the most popular techniques which employs soft power scaling approaches at the relay nodes. On the other. Buffer-aided relaying is a new paradigm for wireless cooperative networks. Buffer-Aided Relaying With Adaptive Link Selection – Fixed and Mixed Rate. A wireless relay is a codecadaptive RF receiver with single channel relay. It helps easily deployment ...
