The substrate design process, based on a low-cost 3D printer and standard filament with different additive options, is described. The designed substrates have been characterized to obtain their dielectric properties in the range of 0.1 GHz to 4 GHz. Finally, to check the possibility of using the manufactured substrates, two stepped impedance filters have been designed in the RF range. Some of the options offered by the additive techniques in the substrates design have used. The designed filters have been simulated and measured with good results, which demonstrates the possibility of using low-cost 3D printers in the RF circuit design process.","PeriodicalId":217265,"journal":{"name":"2019 UNSA International Symposium on Communications (UNSA ISCOMM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129589945","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 window size is used to pipelined packets on the network and is the means to manage the congestion in a network with an end-to-end approach. In the present work, we design a model for the reduction of the window in order to manage the congestion in a network. The reduction is shallow in-contrary to others approaches in which the reduction is drastic. The purpose of making the modification in the reduction algorithm of the window is to reduce the number of packets in the backbone network without affecting the end system. To do this, we test under NS2, modifying the TCP protocol code and proposing particular scenarios.","PeriodicalId":217265,"journal":{"name":"2019 UNSA International Symposium on Communications (UNSA ISCOMM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130769716","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}

This transceiver is fully passive (obtaining its power from a nearby reader) and therefore, it is suitable for IoT applications that require a wireless means of communications while avoiding periodic battery re-charging. The simplicity of the transceiver circuit makes it attractive for low-cost sensing solutions. Communication between the transceiver and a reader (uplink) is achieved using load-shift keying or backscatter modulation, while communication between a reader and the transceiver (downlink) is accomplished amplitude-shift keying. In both cases, data is formatted using an asynchronous serial format. The transceiver was implemented using off-the-shelf components. A small $8 text{mm}times 10.8 text{mm}$ printed circuit board including the transceiver, a microcontroller and a sensor was fabricated. The performance of the uplink was assessed at different distances between the antennas and at a maximum rate of 2 Mbps. It was found that at 2 Mbps, a bit error rate of $9.07times 10^{-4}$ can be achieved.","PeriodicalId":217265,"journal":{"name":"2019 UNSA International Symposium on Communications (UNSA ISCOMM)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115133751","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}
