In order to support the research in the field, the study of possible infrastructures to enable constant illumination and reliable communication becomes a necessity to pair up the evolution of both fields. Leveraging the fact that LEDs are getting more densely deployed to provide uniform illumination, in this work we present the design of a multi-cell deployment that uses several LEDs as VLC Access Points (APs) for Internet of Things (IoT) applications. We characterize the light emitted by the selected LED and show how this deployment complies with the illumination standards, as well as providing a reliable communication network. We present our design choices for controlling and communicating to the network of VLC APs, and show the required functionalities that must be fulfilled such as power monitoring, power management, and communication management.","PeriodicalId":409604,"journal":{"name":"Proceedings of the Workshop on Internet of Lights","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131335619","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}

In this paper we looked at VLC challenges in Vehicular Communications from Medium Access Control point of view. We proposed Link Adaptive Protocol where a single handshake association and fast handover algorithms prolong VLC connectivity. Moreover, adaptive modulation has been suggested in order to increase the throughput. Simulation results show the link adaptive protocol outperforms slotted-aloha in outage probability and goodput, properly achieving a trade-off between pilot rate and protocol efficiency.","PeriodicalId":409604,"journal":{"name":"Proceedings of the Workshop on Internet of Lights","volume":"86 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121931065","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}

In this paper, considering soil moisture measurement overa specific geographic area as the application, we propose a systemthat consists of drone assisted mobile ground robots(MGRs) thatperform collaborative sensing and communicate with the droneusing visible light. The key idea is to combine aerial images andMGR sensed moisture values to generate a dynamically adaptablemoisture map. Camera communication eliminates the need to estab-lish continuous radio communication in remote locations and offersvisual association that enables the drone to localize the MGRs. Thissystem pushes the state-of-the-art in sensing by accurately sensinga region with high spatio-temporal resolution while optimizing thetime and energy required to create a moisture map of a geographi-cal area. As the sensing resolution is dynamic, we hypothesize thatthe proposed system can efficiently predict, detect, and map soilmoisture hotspots.","PeriodicalId":409604,"journal":{"name":"Proceedings of the Workshop on Internet of Lights","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116629705","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}

Light Emitting Diode (LED) is used as VLC transmitter, while photodiodes or image sensors are used as receiver, depending on the applications and hardware constraints. However, LEDs can be used not only as a transmitter, but also as a receiver in applications where cost is of primary concern. LED as a receiver is sensitive to a narrow band of wavelengths, it is robust to sunlight interference and widely available as compared to other light detectors. This paper surveys the potential and limitations of LED-to-LED communication. It also contributes to identifying the challenges and potential research directions in this rising area of interest.","PeriodicalId":409604,"journal":{"name":"Proceedings of the Workshop on Internet of Lights","volume":"19 20","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113934618","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}
