We consider Transmit-Only (TO) sensor networks, where each group of sensor nodes directly communicate with their cluster head (CH) to report their sensed events. Our model makes use of the residual energy levels in the TO nodes and adapts the CH location accordingly such that it minimizes the energy consumption of the nodes with lowest residual energy. Using simulations, we show our approach can achieve up to a 50% improvement in lifetime compared to the static approach.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77532847","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}

LoRaWAN introduces the Adaptive Data Rate (ADR) mechanism, aiming to deliver a fair compromise between network performance and system reliability. ADR performs adaptive tuning of communication parameters, e.g., the Spreading Factor (SF), which is used to modulate the transmitted signals. Although the performance of ADR has been explored in conjunction with stationary End-Devices (EDs), little is known about its suitability for mobile IoT applications. In this paper, we investigate the performance of ADR in diverse mobility scenarios by leveraging a large amount of LoRaWAN experimental traces, collected in the urban area of Antwerp, Belgium. Using a data-driven statistical approach, we show that, whilst ADR enhances network reliability and coverage in low mobility settings, its beneficial effects decrease as mobility increases, hence calling for possible improvement and optimization.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88381145","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 provide these applications with high network utilization while preventing overload, TCP congestion control (CC) determines the data sending rate to achieve high throughput and/or low delay. CC over highly fluctuating 60GHz networks is extremely challenging -- the high directionality and small wavelength of mmWave make it vulnerable to mobility and blockage. Despite numerous studies on CC in WiFi/LTE, CC in 60GHz remains underexplored. To the best of our knowledge, the only related work on CC in mmWave is~citezhang2016transport. However, it's simulation-based and focuses on 28GHz mmWave cellular. Also, it only looks at loss-based CC algorithms and limited scenarios. We close this gap with a first experimental study that comprehensively evaluates the CC performance over commercial 60GHz WLAN using COTS devices. Our study aims to characterize the behavior and performance of different CC algorithms over 60GHz in a wide range of real-world mobility and blockage scenarios. We believe this is a critical step towards designing mmWave-friendly CC algorithms.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89240582","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}

Rural areas, with their unique socio-economic structure, are particularly vulnerable to such losses. Emergency preparedness and response in rural areas severely lags behind that of their urban counterparts. One of the key limiting factors is the lack of adequate broadband connectivity, which limits agencies' capabilities to (i) disseminate emergency preparedness and response information to residents and (ii) efficiently coordinate in the face of a disaster. In this demo, we will present the EApp; a smartphone application that strives to improve the information access regarding emergencies for rural residents and first responders.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85726305","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}

Over the years, sensing using RF has explored different application domains wherein RF sensing is used dedicatedly for sensing and may or may not be used for productive wireless communication concurrently. In this talk, I would present active and passive RF sensing platforms, wherein active approaches require a transmitter to transmit the signal and measure reflections to perceive the environment and passive relies on ambient transmissions. Furthermore, the platforms I would describe inherently allows for concurrent productive communication for both active and passive sensing. The landscape of concurrent RF sensing and communication is relatively unexplored, allowing students to choose many interesting research problems to choose from and platforms to conduct research.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"132 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90703468","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 reduce the time to market, carriers utilize 5G NR for data plane operations while retaining the existing 4G infrastructure for control plane operations in what is called NSA (Non-Standalone) deployment mode defined as 5G system Phase I. EN-DC is a core technology of NSA 5G which supports the introduction of 5G services under 4G infrastructure. It enables a UE to connect to LTE and NR at the same time whereas the control plane connection is handled by LTE infrastructure. In this case, the UE will have only one single RRC state machine. Note that LTE RRC state machine contains RRC_CONNECTED and RRC_IDLE with different DRX settings while NR RRC has an additional state called RRC_INACTIVE. In this work, we aim to explore network and power characteristics for NSA 5G which introduces a surprisingly high data rate.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"152 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76012471","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}
