Current channel models for MIMO PLC do not consider terminal conditions and are focused on optimizing the average case. For safety-critical applications, however, the line terminations are important, as system performance has to be guaranteed for any conditions-including the worst case. In this paper, we present an analytical and a SPICE1-simulated channel model based on transmission line theory that is capable of incorporating terminal networks. Further, we evaluate the channel capacity and compare three different systems that could be deployed in a multi-conductor environment: A Single Input Single Output (SISO) system, multiple parallel SISO systems and a MIMO system. With our channel model we show that the terminal conditions have an impact on the overall signal attenuation, but also that they affect the relative cross-talk level compared to direct channels. Although we can confirm existing findings that MIMO techniques do provide performance gains, our results show that this is only true above a certain signal-to-noise ratio (SNR). For low SNRs, these gains decrease and in worst case, the gains over a SISO system are lost. Also, parallel SISO systems do not offer robust performance gains over single SISO systems, which discourages their use for safety-critical applications.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131805456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Precise knowledge of both the attenuation and the characteristic impedance of low voltage cables are an important part of the characterization of the propagation channel. This paper presents a method for experimental assessment of these parameters. Measurement results of underground and overhead line twisted cables are obtained and analyzed as these are the most representative cables used in low voltage (LV) distribution networks. Using LCR-Meter, two variants of the measurement method are proposed to investigate the real and imaginary parts of the propagation constant. The influence on the characteristic impedance is discussed and the transmission line characteristics are presented as a function of the frequency for both types of cables. One of these variants makes use of approximations, so the effects of this approximation on the secondary parameters are outlined.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129354286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of smart devices creates a heterogeneous type of network with a variety of throughput and delay sensitive applications that must coexist in the HAN. Meeting the quality of service (QoS) for various applications requires high MAC throughput, low channel access delay and prioritized channel access for certain types of data. The Medium Access Control (MAC) protocol for PLC, defined in HomePlug and IEEE 1901, exhibits significant degradation in MAC throughput and increasing channel access delay when the number of users increases. PLC MAC layer issues have received relatively modest attention of researchers compared with physical layer problems and as a result relatively little improvement in MAC throughput and delay performance has been reported over the standard IEEE 1901 protocol. This paper studies an adaptive contention window PLC MAC protocol with a view to assessing access delay performance of this modified protocol, with the throughput and prioritized traffic classes. In the adaptive protocol, each node observes the channel status and adaptively finds the optimum contention window size. Results demonstrate a significant improvement in both MAC efficiency and access delay for the highest priority class in the presence of lower priority classes. Whereas the MAC efficiency drops down to 10% in standard protocols, the proposed adaptive MAC protocol retains its efficiency at about 81% for up to 100 users. Also, the channel access delay is for the modified protocol is maintained under 200 ms for 100 users compared to more than 1000 ms for the standard HomePlug MAC.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122372249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This standard includes different mechanisms and protocols allowing to deal with the poor transmission performance of the power line channel. In particular, all nodes of the network can act as relay. In 2014, G3-PLC standard, the ITU-T G.9903 recommendation, proposed the LOADng protocol to perform the routing. Blacklisting is a mechanism included in this protocol that deals with bad quality links by ignoring them. However, the blacklisting mechanism suffers from a lack of performance when the density of nodes is too low. Indeed, some bad quality links are the only ones possible to reach some farther nodes so that by blacklisting them, these farther nodes cannot be reached anymore. This is why a solution had to be developed in order to solve this problem. Our solution is the smart blacklisting mechanism that highly reduces the probability of blacklisting a critical link. In this work, we highlight the problem of blacklisting in low densities and compare the performance of classical blacklisting and smart blacklisting. For that purpose, we developed our own simulator in the Contiki/Cooja platform in which we have implemented the LOADng protocol as well as the different features of G3-PLC networks. Based on our tool, we report the results we obtained for different node densities and for different link qualities with the classical blacklisting mechanism, without it and with the smart blacklisting mechanism.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124373830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PLC devices manufactures determine the transmitted signal on the electrical power grid as voltage, based on EN50065-1. However, the transmitted signal (voltage) often does not reach the specified signal in EN50065-1 because of the energy efficiency rules of PLC devices. The power consumption limitation of PLC devices is realized by reduction on the power amplifier (PA) output voltage level. The PA output reduction is implemented by current regulator based on current measurement. As a consequence of the PA output level reduction, the transmitted signal reduces at the transmitter and receiver side which reduce the performance of the PLC systems and the data rate as well. In this paper we present the effect of the access impedance by reducing the data rate of PLC systems. In our simulation, we find the achievable data rate considering access impedance values related to EN50065-1 and measurements done in China and Austria. We introduce optimization algorithms to improve the achievable data rate by disabling subcarriers in frequencies with low access impedance which increases automatically the signal on the other subcarriers with sufficient access impedance. These algorithms can be combined with most of PLC standards since the modification on the transmitted signal is only produced from the PLC channel and the receiver should be able under specific constraints to handle these changes.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116880524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
