Such networks deal with mobility, large number of users, and infrastructure issues like unplanned routers deployment. However, the network management is difficult in such cases and may distribute the traffic unevenly between access points (APs). Load balancing the traffic between the APs improves the QoS perceived by users, and the network performance during periods of congestion. The available solutions are non-standard and present lack of interoperability. These problems motivate the implementation of flexible load balancing schemes, in a scalable and centralized network architecture like SDN (Software Defined Networks). SDN centralize the network administration enabling control applications. This paper presents the implementation of a load balancing application based on Round Robin, in a prototype of an institutional wireless network. The experiments test the algorithm performance for single AP, developed in POX, and its extension to multiples APs including a seamless handoff process, using 5G-Empower. The proposed implementations show throughput improvements compared to traditional scenarios.","PeriodicalId":447783,"journal":{"name":"2019 IEEE Colombian Conference on Communications and Computing (COLCOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128174070","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 sense, network administrator management is evolving towards centralized, scalable and resilient processes that go beyond the data center limits and reach WAN providers. This transition supports its foundation in the implementation of cloud-based solutions in conjunction with traditional technologies, giving rise to hybrid scenarios that meet the needs of users and increasingly demanding organizations. This paper proposes the deployment of a hybrid cloud formed by the convergence between a public cloud (Azure) and a private cloud (Openstack) through a secure channel consisting of a virtual private network (VPN). The main objective is to evaluate performance metrics in high traffic scenarios (iPerf) and VoIP services (SIPp). Stress tests are performed to determine the throughput in the hybrid cloud, demonstrating its success and efficiency.","PeriodicalId":447783,"journal":{"name":"2019 IEEE Colombian Conference on Communications and Computing (COLCOM)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131644607","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}

Sometimes it is not always possible to have a link or permanent access to the Internet. This project provides the basis to look for an alternative that facilitates the control and monitoring of lights and electronic devices through a telephone call, through the use of an IP PBX. This research exposes the guidelines and activities carried out for the design and implementation of a prototype for the supervision and monitoring of lights and electronic devices through a PBX, using a wireless solution based on IoT, which serves as a base for the search of technological solutions using platforms of access and development as Arduino and Raspberry, obtaining energy and economic savings. Likewise, seeks to optimize the variables of time, cost and benefit that can provide the communities the use of domotic systems, the use of the necessary resources provided by data networks and telecommunications to perform actions remotely. For this, VoIP systems are used, converting the Raspberry card into a PBX plant with the software on a server based on Asterisk and two extensions were configured with the SIP telephony protocol, one of the most used at a corporate level. With respect to IoT, its four pillars (People, Processes, Data and Things) have created the need to have a society that empowers the new generations of digital citizens who understand the emerging technologies offered by IoT, the impact it has on the community, the widespread adoption of the same and the correct application of the information captured. For the prototype, we have used components (sensors) that can work, or that can act as a starting point for an IoT solution.","PeriodicalId":447783,"journal":{"name":"2019 IEEE Colombian Conference on Communications and Computing (COLCOM)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121810911","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}

For example, in these cases, a child can have cerebral palsy and hearing loss concomitantly. Working with children with multiple disabilities constitutes a challenge, given that they present affectation in several development areas. For these reasons, we have developed a system to support the educational and therapeutic intervention for children with multiple disabilities. Our system relies on an electronic device and an ontology that models some of the most relevant entities and relations of therapy sessions. This proposal has been validated in two stages: (i) a preliminary validation (aesthetic and functionality) with 37 volunteers (higher education students), and (ii) a validation on a real scenario with 6 children with multiple disabilities during a period of two months. The results show high levels of motivation when children work with the device and positive comments by therapists and educators side.","PeriodicalId":447783,"journal":{"name":"2019 IEEE Colombian Conference on Communications and Computing (COLCOM)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132174629","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}
