Both SAND and Q-SAND protocols were successfully implemented in Contiki, an open source operating system for Wireless Sensor Networks and the Internet of Things, and extensively tested using Cooja simulator for Tmote Sky nodes with 6-sectored antennas. The neighbor discovery times were analyzed and analytical expressions were found showing that the time needed to discover all sensor nodes of a network is proportional to the number of nodes in that network. The proposed enhancements to SAND protocol speed up the discovery process up to K times per node, being K the number of sectors of the sectored antenna. Our experiments based on simulations show that for a 6-sectored antenna the time is reduced by 4 times per node, with a greater impact in time and power consumption in networks of increasing size. The Q-SAND protocol performance has been verified through simulations for different network topologies and sizes and compared with that of SAND.","PeriodicalId":149671,"journal":{"name":"2018 Ninth Argentine Symposium and Conference on Embedded Systems (CASE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120980049","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}

IEC 61131–2 is used as product standard and IEC 61000–4 series as specific test standards. For functional performance testing a simple application is developed. Test results show that the CIAA presents some issues regarding immunity, particularly related to electrostatic discharges, fast transient bursts, and radiofrequency interference. Solutions for those problems are proposed, carried out and tested, showing that most of them can be solved using simple design considerations explored in this paper. These improvements can be applied to other industrial controllers as well, in order to enhance their electromagnetic immunity.","PeriodicalId":149671,"journal":{"name":"2018 Ninth Argentine Symposium and Conference on Embedded Systems (CASE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116661073","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 present work describes a prototype of an open hardware wheeled mobile robot for educational purposes –the EduRoMAA. This robot is designed to be used as an experimental platform in embedded system programming courses, covering from the initial to advanced level, using different processing boards such as: Arduino and EduCIAA. A detailed description of the mechanical and electronic parts, as well as a PC application for testing the robot is presented. Tested processing boards are described, including their pros and cons.","PeriodicalId":149671,"journal":{"name":"2018 Ninth Argentine Symposium and Conference on Embedded Systems (CASE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130155985","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 proposed architectures are based in the Radix algorithm. In particular, a radix-2 and a radix-4 are implemented. The main objective is to achieve a very small footprint, in terms of the resources/space demanded by the core, keeping the performance of the standard FFT cores used as ISDB-T OFDM modulator, which will be the final use of the core. Radix algorithm has been selected because it provides high re-utilization, implemented over an iterative structure, using only one design of a butterfly module, multiplier and memory. In this scheme, the main complexity is in the control unit and the datapath. The FFT core is described using the Verilog hardware description language and the test scripts were written in the Matlab script language.","PeriodicalId":149671,"journal":{"name":"2018 Ninth Argentine Symposium and Conference on Embedded Systems (CASE)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127565709","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}

However, the first difficulty that developers face in the implementation and deployment of a LoRa network is the appropriate selection not only of the hardware but also the network server software. Likewise, it is essential to have a testbench to evaluate and configure the network optimally before its actual deployment. This is due to the large number of parameters that must be configured for proper operation of the network, which are dependent on the application scenario. In this paper, we will introduce the main features of LoRaWAN wireless communication technology, a comparison of the main features of hardware and network server software currently available. Finally, we show the first implementation and results of a LoRaWAN testbench and the difficulties detected.","PeriodicalId":149671,"journal":{"name":"2018 Ninth Argentine Symposium and Conference on Embedded Systems (CASE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120964288","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}
