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.

Intercom System

In the TCP/IP building intercom system, broadcast addressing or query-list addressing are often used to obtain the IP address of the called party. However, these methods are limited by the function of the network equipment, intolerable resource costs, and high failure rate of querying. To solve such problems, this paper presents a networking and addressing method in the TCP/IP building intercom system which is based on Distributed Hash Table (DHT). Results from theoretical analysis and simulations show the feasibility and superiority of such a method.

Basic Characteristics

The role of Internet Protocol (IP) is becoming more and more problematic especially with the new requirements of mobility and multihoming. Host Identity protocol (HIP) defines a new protocol between the network and transport layers in order to provide a better management to those requirements. The protocol defines a new namespace based on cryptographic identifiers which enable the IP address roles dissociation. Those new identifiers identify hosts rather than IP addresses. Because HIP is a quite recent protocol, we propose to present an experimental evaluation of its basic characteristics.

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.
