Compressão de dados sem perdas para dispositivos IoT
In environments with energy and processing constraints, such as sensor networks and embedded devices, sending raw information over wireless networks can be costly. In order to reduce the amount of transmitted data and ultimately save energy, we can compress data before transmission. In this paper, we tackle such problem in the IoT domain by deploying two widely used libraries to deliver asynchr...
متن کاملNew Approach of Estimating PSNR-B For De-blocked Images
Measurement of image quality is very crucial to many image processing applications. Quality metrics are used to measure the quality of improvement in the images after they are processed and compared with the original images. Compression is one of the applications where it is required to monitor the quality of decompressed / decoded image. JPEG compression is the lossy compression which is most ...
متن کاملCross-Layer QoS Support in the IEEE 802.16 Mesh Network
In this paper, we propose a framework for QoS support in the IEEE 802.16 Mesh network. For performance improvement over the two basic scheduling schemes recommended in the standard, centralized and distributed scheduling, the framework adopts the idea of BS-controlled route selection and delay-based scheduling. Core mechanisms including mapping of IP QoS classes to 802.16 QoS types, admission c...
متن کاملModelagem de Bancos de Dados em Tempo-real
Neste trabalho introduzimos um método para a modelagem de Banco de Dados em Tempo-real (BDTR) utilizando uma notação de redes de Petri baseadas em objetos denominada EG-CPN. Esta notação é enriquecida de modo a promover a descrição eficiente de modelos integrando BDTR e Sistemas em Tempo-real (STR). O método disponibiliza para o projetista construções que permitem, por exemplo, declarar restriç...
متن کاملMecanismos de Controle de Admissão Baseado em Medições em Redes IEEE 802.11e
Although the 802.11e extension of the IEEE 802.11 standard for wireless local area network was concerned to provide Quality of Service, such provisioning cannot be achieved without specific traffic control mechanisms. In this paper, the use of admission control based on measurement for QoS provision in 802.11e networks is evaluated. It is shown that QoS differentiation can be obtained with the ...
