Many Internet of Things (IoT) requirements are already at the core of next generation wireless networks, including 5G, cognitive radio and future Internet. There is a huge consilience that the majority of Internet devices will become sensors and actuators equipped over ordinary “things”. As a consequence, the radio environment will increasingly become crowded with thousands [...]
Many companies nowadays are struggling to understand the unprecedented complexity of developing business models for products and services based on the Internet of Things. This article aims at investigating what are the elements to be taken into account in order to create a business model for IoT-based products/services and what are the main challenges faced [...]
Redes de computadores são dinâmicas e requerem constante atualização e monitoramento de operações para atender ao crescente volume de dados trafegados. Isso gera diversos problemas de custo, bem como no gerenciamento e ajuste de desempenho para oferecer uma qualidade de serviço (QoS) granular, balancear a carga dos dados e controlar a ocorrência de congestionamentos. Como [...]
The elasticity feature of cloud computing has been proved as pertinent for parallel applications, since users do not need to take care about the best choice for the number of processes/resources beforehand. To accomplish this, the most common approaches use threshold-based reactive elasticity or time-consuming proactive elasticity. However, both present at least one problem related [...]
Internet of things (IoT) has been deeply challenging current Internet and emerging architectures, including 5G and Future Internet. Many architectural limitations, such as weak security, data distribution efficiency, provenance and traceability of sources, excessive human intervention, lack of interoperability and service-awareness in devices configuration, have been exposed and called the society attention. This paper addresses [...]
As a result of rural and suburban migration to the cities, urban life has become a significant challenge for citizens and, particularly, for city administrators who must manage the sustainable use of resources such as energy, water, and transportation. Smart cities are the biggest vision to efficiently address these challenges through a real-time monitoring, providing [...]
he increased adoption of electronic commerce for selling products and services creates a new channel between consumers and vendors. Commonly, e-commerce platforms are assembled as proprietary and centralized solutions. This method has a high financial cost and slows the entry of both middle and small-sized companies into this communication channel. In this context, this article [...]
Information and communication technology (ICT) has transformed the health care field worldwide. One of the main drivers of this change is the electronic health record (EHR). However, there are still open issues and challenges because the EHR usually reflects the partial view of a health care provider without the ability for patients to control or [...]
The advances in the Information and Communications Technology (ICT) brought many benefits to the healthcare area, specially to digital storage of patients’ health records. However, it is still a challenge to have a unified viewpoint of patients’ health history, because typically health data is scattered among different health organizations. Furthermore, there are several standards for [...]
Internet of Things networks together with the data that flow between networked smart devices are growing at unprecedented rates. Often brokers, or intermediaries nodes, combined with the publish/subscribe communication model represent one of the most used strategies to enable Internet of Things applications. At scalability viewpoint, cloud computing and its main feature named resource elasticity [...]
