Recent Developments in Mobile Cloud Scheduling: State-of-the-Art, Challenges and Perspectives, Journal of Telecommunications and Information Technology, 2013, nr 4
Cloud computing became recently one of the most popular multi-layer distributed computational and data processing environments with various types of services, distributed data storages and resources. With rapid development of mobile technologies, computational clouds have been transformed into the systems with dynamically changing topology and flexible infrastructure through integration with the mobile devices and mobile users as the whole system nodes and actors. The aim of this paper is to provide a comprehensive study and critical comparative analysis of the recent developments in the Mobile Clouds with a new energy optimization criterion scheduling
Communications with QoS in IoT&Cloud environment
Dissertação de mestrado integrado em Engenharia de Telecomunicações e InformáticaWith advances in communication technology the future internet presents numerous
opportunities to develop new systems designed to make day to day life easier
and to enhance and prolong the life of people with disabilities. Internet of Things
(IoT) objectives are; enabling a more extensive interconnection of devices; delivering
information perception; enabling development of more comprehensive intelligent services.
Is this motivation that propels the development of new services that integrate
the mobility of cloud systems and the diversity of IoT.
It will enable us to create new and more independent care systems for people
with special needs, providing them a certain degree of independence from others,
such are caregivers or their families. This can have a psychological and social impact
due to the better quality of life that enables. Other motivation is, the versatility and
mobility of services it can provide to everyone by making those services available
anywhere through the internet.
In this thesis is explored and explained the different kinds of technologies that
can be integrated in order to enable the creation of the future Internet platforms
based on IoT and Cloud Computing. Relevant technologies for this thematic such
as Next Generation Networks (NGNs), Body Sensor Networks (BSNs), cloud computing,
IoT and IP multimedia Subsystem (IMS), are explained. Several Quality of
Service (QoS) experiments were conducted in IoT&Cloud platform. The obtained
results were analyzed and the main findings were used to recommend the main
requirements for a platform that underlies in IoT and Cloud technologies. Furthermore,
a system architecture fulfilling the requirements pointed out as demanded is
proposed and its functionalities are exemplified in a specific scenario.
The proposed system is then implemented and tested in order to ascertain the
feasibility of the implementation and the performance of communications. The thesis
ends with the conclusion on the findings and future work that still needs to be done.Com os avanços nas tecnologias de comunicação a Internet do Futuro apresenta
numerosas oportunidades para desenvolver novos sistemas projetados para fazerem
a vida do dia a dia mais fácil e para melhorar e prolongar a vida de pessoas com
carências especiais. Os objectivos da Internet of Things(IoT) são; permitir uma interconexão mais extensa dos dispositivos; fornecer perceção da informação; permitir
o desenvolvimento de serviços inteligentes mais compreensivos. E esta motivação
que impulsiona o desenvolvimento de novos serviços que integram a mobilidade dos
sistemas cloud e a diversidade da IoT.
Isto vai nos permitir criar novos e mais sistemas de cuidados independentes para
pessoas com carências especiais, permitindo-lhes um certo grau de independência
de outros, tais como cuidadores ou as suas famílias. Isto pode ter um impacto
psicológico e social devido a qualidade de vida que proporciona. Outra motivação
é a versatilidade e mobilidade de serviços que pode fornecer a todos ao tornar esses
disponíveis em qualquer lado através da internet.
Nesta tese são explorados e explicados os diferentes tipos de tecnologias que
podem ser integradas de forma a permitir a criação de plataformas de internet do
futuro baseadas em IoT e Cloud Computing. São explicadas tecnologias relevantes
para esta temática tais como Next Generation Networks(NGNs), Body Sensor Networks(
BSNs), cloud computing, IoT e IP multimedia Subsystem(IMS). Foram conduzidas
várias experiências em uma plataforma IoT&Cloud. Os resultados obtidos
foram analisados e as conclusões usadas para recomendar os requerimentos principais
de uma plataforma que tem como base as tecnologias IoT e Cloud. Além disso,
é proposta uma arquitectura de sistema que preenche os requisitos enunciados e as
suas funcionalidades exemplificadas em um cenário específico.
O sistema proposto é depois implementado e testado de modo a determinar a
viabilidade da implementação e o desempenho das comunicações. A tese acaba com
a conclusão dos resultados obtidos e trabalho futuro que ainda necessita ser feito
Implementing Mobile Health Records in Low-Resource Settings
The gradual adoption of electronic medical records (EMR) in resource rich nations has been a challenging task but one that has improved the quality of health care and reduced medical errors. Creating large scale EMR systems is still difficult for medical facilities in developed nations but even more of a lofty goal for developing countries where resources are scarce and the infrastructure is still in its infancy. In developed countries, there is no one correct implementation of EMR systems and they were built to suit the needs of specific medical facilities. Likewise, it is impossible to suggest a single EMR system that would fit all contexts in developing countries. Thus, this paper focuses on low resource settings in developing countries where there is limited infrastructure and resources.Bachelor of Scienc
Securing authentication and trusted migration of weblets in the cloud with reduced traffic
Cloud computing is making a new revolution in the computing world. Elasticity is one of the key features of the cloud which makes cloud computing further fashionable. Cloud is still in its infant stages and it faces a wide range of security threats. The security downtime of cloud is relatively slowing down the spreading up of cloud computing. This paper focuses on the security threats faced by the web lets during their migration between the cloud and the mobile devices. Web let migration is an important task during the implementation of elasticity in the cloud. As a primary step, a secure communication channel is designed for the web let migration by deploying secure shell protocol. Herein, the vulnerabilities in some authentication mechanisms are highlighted and a better way of authenticating the web lets with SFTP (Secure File Transfer Protocol) is suggested. Finally, managing the traffic effectively in the designed channel with the aid of back pressure technique is also covered in this paper
