    Analyzing downloaded data from road side units
    (Universidad de Cuenca, 2014) Astudillo S., Darwin; Barros G., Juan Gabriel; Chaput, Emmanuel; Beylot, André-Luc; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca; DIUC
    In the context of vehicular networks a map updating application was analyzed, which enables vehicles to download relevant geographic data related to their position. Possible strategies for data sharing are the networks from infrastructure to a vehicle (I2V) and from vehicle to vehicle (V2V). In this study two chunking techniques, the Random Sort Strategy (RSS) and the Network Coding (NC), for the I2V network segment were compared. The study revealed that the distribution of different received chunks is independent of the file size when NC is used; when RSS is used the mean and standard deviation depend on the file size. The authors intend to integrate in a next step these results in the analysis of the V2V network segment.

    Off-the-shelf platform for remote monitoring of vital signs
    (Universidad de Cuenca, 2015) Barros G., Juan Gabriel; Astudillo S., Darwin; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca; DIUC
    This document shows work-in-progress in the implementation of a platform for remote monitoring of health care data using ready to use devices. The goal is to provide an easy-to-use application to gather specific control parameters directly related to type 2 Diabetes Mellitus. The idea of remote monitoring for e-health is not new but there exist open questions about the radio technology to use in these applications. Some standards are often associated with these kinds of applications, standards such as: IEEE 802.15.4 and ANT+. We try to explore the benefits of using out of the box technology to reduce development and deployment time of applications sending gathered data over the Internet. The utilization of Smartphones as concentrator node is also discussed, as it make possible to use sensors already embedded in the device as well as other multipurpose and ready to use sensors using ANT+ technology.
