Mobile Edge Computing Empowers Internet of Things
In this paper, we propose a Mobile Edge Internet of Things (MEIoT)
architecture by leveraging the fiber-wireless access technology, the cloudlet
concept, and the software defined networking framework. The MEIoT architecture
brings computing and storage resources close to Internet of Things (IoT)
devices in order to speed up IoT data sharing and analytics. Specifically, the
IoT devices (belonging to the same user) are associated to a specific proxy
Virtual Machine (VM) in the nearby cloudlet. The proxy VM stores and analyzes
the IoT data (generated by its IoT devices) in real-time. Moreover, we
introduce the semantic and social IoT technology in the context of MEIoT to
solve the interoperability and inefficient access control problem in the IoT
system. In addition, we propose two dynamic proxy VM migration methods to
minimize the end-to-end delay between proxy VMs and their IoT devices and to
minimize the total on-grid energy consumption of the cloudlets, respectively.
Performance of the proposed methods are validated via extensive simulations
Edge analytics in the internet of things
High-data-rate sensors are becoming ubiquitous in the Internet of Things. GigaSight is an Internet-scale repository of crowd-sourced video content that enforces privacy preferences and access controls. The architecture is a federated system of VM-based cloudlets that perform video analytics at the edge of the Internet
Cloudlet Deployment to Balance Energy Consumption in Wireless Networks: A Survey, Issues and Challenges
Cloud computing and wireless networks, both are two different important components in information technology (IT) world. These both wide network components are unlike from each other and their characteristics are providing huge services. By using these services, users getting several computing services at low cost while providing the security and privacy. According to the one survey till end of the 2016, gross payments from the e-commerce business management was spent $4 billion for maintenance of datacenters. Energy consumption is the key component in the information technology world, because due to the wastage usage of computing hardware components like servers, datacenters and network bandwidth etc., business profits will be go down. So, by integration of these two areas, online business management will get more revenues while providing the QoS. The proposed mechanism, deploying the cloudlets for executing the actions, which are belongs to the wireless networks such as Local Area Network (LAN), Metropolitan Area Network (MAN) and Wide Area Network (WAN) etc. The proposed idea addressed better solution to avoid Service Level Agreement�s (SLA) violations and poor QoS
Next Generation Cloud Computing: New Trends and Research Directions
The landscape of cloud computing has significantly changed over the last
decade. Not only have more providers and service offerings crowded the space,
but also cloud infrastructure that was traditionally limited to single provider
data centers is now evolving. In this paper, we firstly discuss the changing
cloud infrastructure and consider the use of infrastructure from multiple
providers and the benefit of decentralising computing away from data centers.
These trends have resulted in the need for a variety of new computing
architectures that will be offered by future cloud infrastructure. These
architectures are anticipated to impact areas, such as connecting people and
devices, data-intensive computing, the service space and self-learning systems.
Finally, we lay out a roadmap of challenges that will need to be addressed for
realising the potential of next generation cloud systems.Comment: Accepted to Future Generation Computer Systems, 07 September 201
