The Internet Of Things

In upcoming smart urban environments, various things can be interconnected, and the Internet of Things (IoT) can be used to construct a safer and more convenient urban environment. Things in the IoT need an addressing system that can uniquely identify each one; internet protocol (IP) addresses can be used for this purpose. The IP address the two roles of an identifier and a locator. However, this binding has problems related to mobility and multihoming, and it is hard to deploy on a legacy IP system because of some limitations of sensor devices. To solve the problem, we propose a design for software-defined networking (SDN)-based identifier–locator separation architecture on IoT networks. In the proposed scheme, Internet Protocol version 6(IPv6)-based addresses are used for the identifiers and locators. The network is partitioned into a host identity domain for local routing and an IP domain for global routing. The host identity domain operates as an overlaid network over the IP domain, and it makes the unrouteable identifiers routable with a distributed hash table (DHT)-based routing strategy. For the evaluation of the proposed scheme, a packet forwarding cost and signaling cost model is calculated, and the results show that the proposed scheme is conjugable to an IoT network environment.

This paper presents the implementation of an agent-based architecture suitable for the coordination of power electronic converters in stand-alone microgrids. To this end, a publish-subscribe agent architecture was utilized as a distributed microgrid control platform. Over a distributed hash table (DHT) searching overlay, the publish-subscribe architecture was identified based on a numerical analysis as a scalable agent-based technology for the distributed real-time coordination of power converters in microgrids. The developed framework was set up to deploy power-sharing distributed optimization algorithms while keeping a deterministic time period of a few tens of milliseconds for a system with tens of converters and when multiple events might happen concurrently. Several agents participate in supervisory control to regulate optimum power-sharing for the converters. To test the design, a notional shipboard system, including several converters, was used as a case study. Results of implementing the agent-based publish-subscribe control system using the Java Agent Development Framework (JADE) are presented.

BACKGROUND: Originally, digital healthcare was created to support underserved and rural patients gain access to health services. Phones, devices, and computers need IP (Internet Protocol) addresses to connect to the Internet. OBJECTIVE: This paper aims to study the close relationship between the Internet and the transformation of healthcare services. METHODS: The current protocol in use is the Internet protocol version 4 (IPv4), whose number of Internet addresses has been globally exhausted. The Internet Protocol version 6 (IPv6) with 47 octillion unique addresses for every person on the planet has become the only option for sustainable growth and innovation. However, most of the worldwide industry is still in IPv4. In the era of Artificial Intelligence, Internet of Things, Fifth Generation of Cellular Technology (5G), and Blockchain, there will be a massive need of IP addresses. For 2025, experts predict over 1.5 billion new IPv6 users which will continue to grow exponentially. RESULTS: Nations need to tackle the increasing industry requirements for IPv6 and telehealth adoption to benefit from the full IPv6 connectivity which is the key strategic advantage for the healthcare industry. CONCLUSION: The strategic potential that telehealth brings to the healthcare industry is widely appreciated. However, what are the implications of its expansion around the world? How can we prioritize the poorest and most vulnerable in society without new technologies?

The wan Internet storage system based on Distributed Hash Table uses fully distributed data and metadata management, and constructs an extensible and efficient mass storage system for the application based on Internet. However, such systems work in highly dynamic environments, and the frequent entry and exit of nodes will lead to huge communication costs. Therefore, this paper proposes a new hierarchical metadata routing management mechanism based on DHT, which makes full use of the node stabilization point to reduce the maintenance overhead of the overlay. Analysis shows that the algorithm can effectively improve efficiency and enhance stability.
