This paper presents the problem of optimizing Radio Access Technology (RAT) selection and traffic offloading in a Multi RAT Heterogeneous Network composed by cellular and WiFi networks. The main idea is to distribute the traffic load of the system over the available access networks, while making an efficient use of the radio resources in the long-term. In this sense, a higher and fair WiFi resource...
Quality of Service (QoS) provision is a mandatory requirement when transmitting telemedicine traffic, because of the relevance of the information for the patient's health. Active queue management has become a widely chosen strategy to provide QoS, since it does not require interaction with network equipment. This document proposes a new access control scheme based on the occupation of the queue and...
Video streaming services have been developed using different approaches. Peer-to-peer (P2P) streaming is a competitive technique in the distribution of video contents, thanks to its collaborative and sharing features. Nowadays, several applications distribute television contents over a P2P platform, broadcasting plenty of channels to an increasing audience. The performance of such applications over...

The increasing interest in developing solutions for applications, such as industrial automation, body sensor networks, natural risks management and prevention; without the need of a wired media has encouraged the development of a low data rate and low power consumption wireless communication systems, commonly known as Wireless Sensor Networks (WSN). Although many proprietary solutions have been proposed,...
This paper presents a simple and low cost method to estimate relative permittivity and tangent loss for dielectric sheets used in printed circuit boards (PCB's). The process starts by building a rectangular cavity in a very easy manner. As an example, the results to estimate relative permittivity and tangent loss of a fiber glass PCB are shown. The relative permittivity and tangent loss are presented...
Wireless mesh networks (WMN) enables the expansion of communication networks and broadband services. This expansion allows the use of applications like streaming multimedia in P2P (Peer-to-Peer). P2P-TV and WMNs share similar features like self-organization and decentralization in dynamic network environments and multi-hop transmission. In this context quality measurement has become essential due...
Often chronic patients fail to follow all the recommendations in their treatments. This affects their health and increases the costs associated with their care. To help these patients to follow their therapy this paper proposes a recall and guide system implemented on a mobile device. The system emits custom messages according to the patient's inferred mental state with the intention of persuading...
