The load status of the TBS is analyzed by control base station (CBS) to realize the rational use of resources. For the heavy-load TBS, CBS control traffic base station (TBS) to perform adaptive cell zooming to optimize user association and achieve load balancing. For the light-load TBS after cell zooming, it should be put into sleeping state to save energy consumption of TBS and reduce interference to active users. In addition, the adaptive clustering sheme is used to alleviate the degradation of user signal quality after cell extending. Then, the integral expression of the coverage probability and the edge spectral efficiency are derived by the stochastic geometric. Numerical simulation analysis is performed and the results show that the proposed scheme gives notable gains in edge spectral efficiency compared to the existing schemes.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130399531","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}

We prepared blue and green emitting PLEDs using commercial light-emitting polymers, and then characterised the device emission (spectrum and power), and extracted their circuit parameters for their electrical equivalent model for driving with small signals. In addition, we characterised the bandwidth ($boldsymbol{B_{mod}}$) of the devices over a period of continuous driving (∼ 4 h) and found that for the blue PLEDs the $boldsymbol{B_{mod}}$ decreased from an initial 750 kHz to a steady state of ∼250 kHz. The green-emitting devices were found to benefit from an extended $boldsymbol{B_{mod}}$ of ∼1.5 MHz at the beginning of the test, which then stabilised to ∼850 kHz. Furthermore, with the addition of a first order RC filter we show that, the steady state $boldsymbol{B_{mod}}$ of the blue PLED cane be increased by a factor of ∼3, thus allowing > 1 Mbps non-return to zero on-off keying (NRZ OOK) data transmission in a complete VLC system.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117316450","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 solar energy which is collected by the solar module is converted and stored into a voltage source of electrical energy. In terms of maintenance process, if there are a large number devices of Public Street Lighting, the problem of efficiency arises. The maintenance becomes inefficient if the process has to be conducted one by one for each point and carried out for a time continuously. In this paper, one alternative method is proposed by using a data logger developed using an ATmega328 microcontroller on the solar module of Public Street Lighting. Here, data logger will record and store all data flows and voltages that work on the device. The data which are stored into SD Card storage every 1 minute will be easily accessed and monitored via a personal computer (PC). The performance result shows that the output voltage is influenced by the intensity of light received by the solar module. The output voltage is about 15 volt which corresponds to the received light intensity of 69.4%.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114766128","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 fact, it is expected that the number of devices connected to the Internet will exceed 50 billion by 2020. It is possible to use these infrastructures for environmental monitoring systems, especially for the early detection and prevention of disasters such as forest fires. Wireless sensors are an essential part of the IoT infrastructure and environmental monitoring/surveillance systems. Wireless sensor networks based on scalar sensors and wireless multimedia sensor networks are widely used for environmental monitoring. Multimedia surveillance systems have better accuracy but a shorter lifetime with multimedia surveillance systems. Therefore, it is necessary to study in detail their energy efficiency to better understand the introduction of more efficient algorithms and architectures. In this study, the lifetimes of the Wireless Sensor Networks(WSNs) and Wireless Multimedia Sensor Networks(WMSNs) are considered in a comparative way. The results are presented for a forest fire detection case study using simulations as well as an example of a test bench to confirm the accuracy of the simulation tool used.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131793546","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}
