The 5G NR is anticipated to enable reliable vehicular networking, with emphasis on Vehicle-to-Everything (V2X) communications. Here, 5G NR is required to support V2X Side Link (SL) communications for C-Plane signaling via wireless Uu interface, which naturally suffers from fading and path loss. Therefore, relaying can address this concern by deploying a low power relay node (RN) in 5G NR network. This paper presents the end-to-end (e2e) performance of dual-hop relaying under four different relay selection schemes and different RN density/deployment scenarios. These selection schemes comprised of the combinations of average and/or instantaneous wireless channel conditions of the two links involved in the transmission, wireless backhaul relay link (RL) and access link (AL). Simulation results demonstrate that when relay selection is performed relying on the instantaneous e2e link conditions, the best performance in terms of average e2e data rate can be obtained. Moreover, higher RN density in network, yields enhanced performance, due to the availability of additional paths to select from, especially, when RNs are randomly deployed rather than at fixed locations.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122467078","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 limitation of energy, in particular, has a significant impact on the system’s performance, especially because the overall energy consumption is frequently dominated by the cost of communication, i.e. the computational and sensing energy are insignificant in comparison to the communication energy consumption. As a result, the system’s lifetime may be considerably prolonged by reducing the communication as well as the volume of communication data, at the penalty of increased computing cost. This work presents a hierarchic approach for allocating multi-UAV resources based on a cooperative and competitive particle swarm optimization (PSO) algorithm, with the goal of achieving an optimal balance between communication and processing energy. According to the simulation findings, our technique can save a substantial amount of energy when compared to a benchmark strategy namely random search (RS) and PSO.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125504990","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}

Researchers have adopted blockchain as an interesting and trendy research topic in the wireless ad hoc environment. Due to its strong characteristics, such as consensus, immutability, finality and provenance, it’s used not only as a secure data storage for critical data, but also as a platform that facilitates trustless data exchange between independent parties. However, the main challenge of applying blockchain in an ad hoc network is what kind of nodes should be involved in the validation process and how to adopt the heavy computational complexity of block validation in an appropriate way while maintaining its authentic characteristics. In this paper, we propose a new blockchain-based model against selfish attacks in ad hoc networks and optimize it in this context, to this end, we investigate the presence of MPR nodes to adapt and integrate the blockchain principle in MANETs and based on this we conduct a security analysis to evaluate our model by discussing the ability of our model to meet major security issues related to confidentiality, integrity, availability, non-repudiation, and vulnerability to attacks.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129037039","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 proposed scheme relies on the concept of distributed learning by majority vote (MV) with sign stochastic gradient descend (signSGD). As compared to the state-of-the-art solutions, with the proposed method, edge devices (EDs) transmit the signs of local stochastic gradients by activating one of two orthogonal resources, i.e., orthogonal frequency division multiplexing (OFDM) subcarriers, and the MVs at the edge server (ES) are obtained with non-coherent detectors by exploiting the energy accumulations on the subcarriers. Hence, the proposed scheme eliminates the need for channel state information (CSI) at the EDs and ES. By taking path loss, power control, cell size, and the probabilistic nature of the detected MVs in fading channel into account, we prove the convergence of the distributed learning for a non-convex function. Through simulations, we show that the proposed scheme can provide a high test accuracy in fading channels even when the time-synchronization and the power alignment at the ES are not ideal. We also provide insight into distributed learning for location-dependent data distribution for the MV-based schemes.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131080815","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}
