To improve the secrecy performan ce of the proposed network, we consider the artificial light induced noise with the aim of disrupting the eavesdropper. More precisely, by considering the dynamic behavior of the network, we formulate the achievable secrecy rate of the legitimate users. To allocate power to legitimate users, we modify two well-known fixed power allocation and the gain ratio power allocation methods to improve the network sum secrecy rate. The num erical results indicate that the secrecy performance of the network is improved at least 2dBs by employing the modified power allocation methods plus the artificial noise compared with the case of using the conventional version of the power allocation methods, which this value scales for higher tran smit p owers. F urtherm ore, the effect of half-power angle of the optical transmitter is considered with simulation results showing an optimum value for the half-p ower angle, which can vary depending on the considered scenario.","PeriodicalId":288069,"journal":{"name":"2022 13th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130189957","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}

When dealing with a large number of sensors coexisting within the same vicinity, multiple access (MA) solutions are necessary to manage the simultaneous access to the medium. In this paper, we investigate the use of MA multi-band carrierless amplitude and phase (m-CAP) for intra-WBAN links. Using the outage probability criterion, we evaluate the performance of such a solution while accounting for realistic statistical channel models. Furthermore, we study the impact of system parameters such as bandwidth, number of sub-bands, and roll-off factor on the link performance.","PeriodicalId":288069,"journal":{"name":"2022 13th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134211218","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 the transmission, the received ECG signal was filtered using Gaussian filter and analyzed using Shannon energy to obtain signal peaks. Accuracy, sensitivity, detection error rate and positive predictive values were evaluated to qualify the signal that is transmitted using OWC system. We carefully characterize the electrocardiogram signals after transmission and found that they present high accuracy.

However, RF links are slow and require authorized permission for satellite and in-orbit applications. Recently, free-space optical (FSO) communication links are trending for satellite applications due to their huge potential for data transmission and low-cost implementation. Ideally, satellites would benefit from both RF and FSO technologies to ensure robustness and reliability. However, such a communication system requires the use of dedicated antenna and aperture for RF and FSO, respectively. The key challenges in the satellite transceiver systems are the size and mass. Therefore, having two separate units for each technology is not desirable. In this paper, we present a unique, compact, robust, and flexible design, which integrates optical wireless communication front-end aperture and radio antenna in a single module. We will present the design concept as well as RF and optics simulation results.","PeriodicalId":288069,"journal":{"name":"2022 13th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122334075","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 amount of research produced, and the available commercial solutions are an indication of this fact. These solutions come in various forms and shapes in terms of complexity, features, and functionality. For a Disaster Management System, visibility and rapid-dynamic response are the keystones. Several proposals attempted to address this requirement with dashboards, node clusters, technology convergence, and event localization. These models employ various tools and platforms for data collection, visualization, analysis, alert management, and integration. However, they fall short of making the system simple and autonomous. This paper proposes a framework to bridge this gap by using low-cost off-the-shelf modules, an Observer node, hybrid connectivity and a message forwarding mechanism between the nodes. Despite being simple at its core, the framework is modular and hence can be extended to support a Disaster Management System of any size. Being open-ended leaves a lot of scope for future integration and scale-out.","PeriodicalId":288069,"journal":{"name":"2022 13th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126344646","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}
