Name Services for the Internet of Things are distributed systems that serve a fundamental lookup function to identify the distributed data for tracing the product. However,the currently specified Object Naming Service (ONS) for the Internet of Things has severe drawbacks ,such as low efficiency and weak security.In this paper, we Put forward a name service architecture based on Pastry algorithm. And an experiment is carried out by OMNET++ simulation platform , experimental results demonstrate that the mechanism in terms of both network throughput, query efficiency has improved greatly compared to ONS.

In the scenario of mass control commands requesting for network access, confined by the best-effort network service mode, it is easy to bring about resource competition and thus a phenomenon of access failure on major and urgent service request at the data access center for the Internet of Things. In this event, the dynamic diversification of control command is unable to access the necessary resources on a comparatively fair basis, causing low efficiency in heterogeneous resource utilization at the access center. This paper defines the problem of group request dynamic resource allocation and further converts it into the problem of 0-1 integer and linear programming and proposes a multistage dynamic packet access strategy. This strategy works first on dynamic group division on the users’ mass control requests using the high ability of self-organizing feature maps and then searches for the optimized matching resources based on the frog-leaping algorithm which has a better capacity for global searching for the best resources. This paper analyzes the feasibility of this strategy and its astringency. The experimental results demonstrate that the strategy can effectively improve the success rate of access to the data center for the Internet of Things and reduce network blockage and response delay.

Embedded Intelligence

The interoperations of endpoint devices are generally achieved by gateways in Internet of Things (IoT) systems. However, the gateways mainly focus on networking communication, which is lack of data logic control capabilities. The microcontrollers with embedded intelligence could work as an intermediate device to help the interconnections of the endpoint devices. Moreover, they could help control the endpoint devices. In this paper, a microcontroller architecture with intelligent and scalable characteristics is proposed. The intelligence means that the microcontroller could control the target endpoint devices by its logical circuits, and the scalability means that the microcontroller architecture could be easily extended to deal with more complex problems. Two real world industrial implementations of the proposed architecture are introduced. The implementations show that the microcontroller is important to provide the intelligent services to users in IoT systems. Furthermore, a simulation experiment based on the cloud model is designed to evaluate the proposed method. The experimental results demonstrate the effectiveness of the proposed architecture.

AbstractThe expansion of Internet has led to a variety of directly accessible devices and services. Nowadays, companies tend to increase the number of Internetfacing services in order to ensure higher visibility, and accessibility towards end-users. Nonetheless, this profound expansion towards an “Internet of Things” brings new opportunities to malicious actors. As a result, novel cyber-physical attacks bring new challenges to systems administrators in order to accommodate traditional user requests with security prerequisites. Therefore, in this paper we propose a novel approach for historical Internet connectivity assessment of services. The technique uses the output of the popular Shodan search engine to infer the lifetime of different Internet-facing services. Experimental results conducted on IP address blocks attributed to six different institutions distributed across four sectors (university, telecommunications, banking, and power) show different possible service lifetime patterns.

Nowadays, the item-level lookup is quickly becoming a key issue in many application scenarios of Internet of Things (IoT). However, as a critical role of IoT, current lookup services and discovery services rely on a centralized or a chain-style framework, thus have some drawbacks, which prevent them from being widely adopted, as well as the item-level lookup service is still missing. Therefore, based on Chord, we presented IDSAa distributed item-level discovery service architecture for IoT, gave its basic framework and some relevant mechanisms to make the lookup services more load-balanced, scalable, and efficient. Additionally, some tests and analysis were given to validate and evaluate our solution. The results show that our solution is available.

The BOINC software package allows the creation of massive computational systems for distributed computing. The system is designed to use heterogeneous computing devices that are differing in hardware architecture and operating systems. The variability and versatility of the BOINC system allows its use to create a distributed system for measurement and data collection. This is done through the standard HTTP and HTTPS web communication protocol that is used on the Internet in connected devices, so called “Internet of things”.
