Designed to operate on batteries, some devices can operate several years without requiring human intervention. However, scheduling reliable wireless communication becomes challenging when considering the energy consumption of the devices. Furthermore, actual industrial network deployments and data traffic are often unpredictable as they greatly vary depending on the field of application. While application-specific solutions exist, an adaptive and application-agnostic solution is preferred. This work proposes a new wireless scheduling algorithm to address the reliability issue in wireless sensor networks, while considering the energy cost. The algorithm operates as a swarm and optimizes the number of communication resources allocated to each device in a short time. Tested on the IEEE 802.15.4 TSCH communication protocol, the algorithm is compared to the Minimal Scheduling Function (MSF), state of the art of TSCH scheduling. The algorithm highlights a strong performance in terms of packets reception ratio and latency. Furthermore, it shows an increased energy efficiency measured in current consumed per delivered packet.","PeriodicalId":102095,"journal":{"name":"2019 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134392601","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}

To achieve these objectives, accurate channel estimation in highly mobile scenarios becomes necessary. In this paper, we propose a tensor modeling-based approach for channel estimation and receiver design in a two-hop multiple-input multiple-output V2X communication system. Specifically, by exploiting a Tucker-2 modeling of the received signals, and relying on the joint estimation of the two-hop link, we formulate simple tensor-based closed-form and iterative semi-blind receivers. Furthermore, motivated by the parallel factor analysis (PARAFAC) structure of the time-varying multipath channel, we develop an iterative algorithm for estimating key parameters of the two-hop channel – including angles of departure, angles of arrival and path gains – from the factor matrices of the estimated channel tensors. Simulation results illustrate the performance of the proposed channel estimation and receiver algorithms in selected V2X communications scenarios.","PeriodicalId":102095,"journal":{"name":"2019 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"373 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123434564","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}

Recognizing the importance of mitigating the effect of these additional interference types, previous works proposed multicell coordinated beamforming to realize the full potential of DTDD systems that employ multiple antennas at the BSs. Unfortunately, the previously proposed mechanisms suffer from slow convergence, which renders such schemes impractical in fast fading and highly mobile environments. In this paper, we formulate the multicell multi-stream DTDD beamforming problem as an optimization task, and propose a near-optimal pricing-based algorithm to determine the beam directions and transmit power levels for each stream at the BSs. The proposed distributed precoding and power control algorithm not only improves the downlink performance, but it also substantially mitigates the BS-to-BS interference levels, and thereby improves the uplink performance as well. Simulation results indicate that the proposed algorithm exhibits faster convergence than previously proposed near-optimal schemes at the expense of some small performance degradation in terms of the achieved signal-to-interference-plus-noise-ratio (SINR).","PeriodicalId":102095,"journal":{"name":"2019 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123519042","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}

After completing the LTE-based V2X standard specifications, 3GPP continues with a 5G-based V2X solution. While IEEE 802.11p-based and cellular-based solutions appear to be two competing solutions, there have been proposals for a hybrid approach in which both technologies co-exist and are used at the same time in a different manner. However, this implies that there are two different security solutions with different architectures: this requires careful consideration to ensure co-existence and operation.

Deploying individual VNF instances for these components could guarantee the customization of each RAN slice subnet. However, due to the multiplicity of VNFs, the required amount of virtual resources will be greater compared to the case where a single VNF instance carries the aggregated traffic of all the RAN slice subnets. Sharing gNB components between RAN slice subnets could optimize the trade-off between customization, isolation and resource utilization. In this article, we shed light on the key aspects in the Third Generation Partnership Project (3GPP)/NFV standards for sharing gNB components. First, we identify four possible scenarios for sharing gNB components. Then, we analyze the impact of sharing on the customization level of each RAN slice subnet. Later, we determine the main factors that enable isolation between RAN slice subnets. Finally, we propose a 3GPP/NFV-based description model to define the lifecycle management of shared gNB components.","PeriodicalId":102095,"journal":{"name":"2019 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"25 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132737367","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 use of commercial low-cost Software Defined Radio (SDR) can contribute to a reduction of the development time and allow the testing of new algorithms and specification solutions for LTE/LTE-A and 5G scenarios. In this paper, a proof of concept of an LTE Decode-and-Forward (D&F) Relay Node using SDR is presented. The developed SDR platform implements LTE Physical Layer (PHY), Medium Access Control Layer (MAC) and some Radio Link Control (RLC) features, using two NI-USRP-2901.
