Big Data A Survey[taliem.ir]

Big Data: A Survey

In this paper, we review the background and state-of-the-art of big data. We first introduce the general background of big data and review related technologies, such as could computing, Internet of Things, data centers, and Hadoop. We then focus on the four phases of the value chain of big data, i.e., data generation, data acquisition, data storage, and data analysis. For each phase, we introduce the general background, discuss the technical challenges, and review the latest advances. We finally examine the several representative applications of big data, including enterprise management, Internet of Things, online social networks, medial applications, collective intelligence, and smart grid. These discussions aim to provide a comprehensive overview and big-picture to readers of this exciting area. This survey is concluded with a discussion of open problems and future directions.

Architecture Design of the Internet of Things based on Cloud Computing

Importance and development advantage of the Internet of Things industry chain is discussed. The basic ideas and methods of the combination of cloud computing and the Internet of things are described. Combined with cloud computing, the unified Internet of Things operation management system framework is established. The framework of the new platform middleware layer uses the cloud computing technology, which greatly improves the operating efficiency of the Internet of things. Based on the framework, Internet of Things business operations platform construction scheme is proposed, it can be used as reference of the construction of the Internet of things platform design.

Energy Efficient Green Routing Protocol for Internet of Multimedia Things

Internet of Things (IoT) envisions the notion of ubiquitous connectivity of ‘everything’. However, the current esearch and development activities have been restricted to scalar sensor data based IoT systems, thus leaving a gap to benefit from services and application enabled by ‘multimedia things’ or Internet of Multimedia Things (IoMT). Moreover, a crucial issue for Information and Communication Technology (ICT) community is the steer increase in CO2 emissions, which mandates green communication to reduce energy consumption and carbon footprint emissions. Recently, IETF ROLL working group standardized an IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) for resource constrained devices. RPL builds a tree-like network topology based on some network metric optimization using RPL Objective Functions. Previous RPL implementations for scalar sensor data communication are not feasible for IoMT, since multimedia traffic pose distinct network requirements. The goal of this paper is to design an enhanced version of RPL for IoMT in which the sensed information is essentially provided by the multimedia devices. Our proposed RPL implementation minimizes carbon footprint emissions and energy consumption, along with the incorporation of application specific Quality of Service requirements. To evaluate the performance of the proposed scheme a simulation study is carried out in Cooja simulator for Contiki-OS, which suggests significant gains in terms of energy efficiency and delay.
