Energy-Efficient Content-Based Routing in Internet of Things  [PDF]
Samia Allaoua Chelloug
Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.312002
Abstract: The?convergence of the Internet, sensor networks, and Radio Frequency Identification (RFID) systems has ushered to the concept of Internet of Things (IoT) which is capable of connecting daily things, making them smart through sensing, reasoning, and cooperating with other things. Further, RFID technology enables tracking of an object and assigning it a unique ID. IoT has the potential for a wide range of applications relating to healthcare, environment, transportation, cities… Moreover, the middleware is a basic component in the IoT architecture. It handles heterogeneity issues among IoT devices and provides a common framework for communication. More recently, the interest has focusing on developing publish/subscribe middleware systems for the IoT to allow asynchronous communication between the IoT devices. The scope of our paper is to study routing protocols for publish/subscribe schemes that include content and context-based routing. We propose an Energy-Efficient Content-Based Routing (EECBR) protocol for the IoT that minimizes the energy consumption. The proposed algorithm makes use of a virtual topology that is constructed in a centralized manner and then routes the events from the publishers to the intended interested subscribers in a distributed manner. EECBR has been simulated using Omnet++. The simulation results show that EECBR has a significant performance in term of the energy variance compared to the other schemes.

Abstract: The term Internet of Things (IoT) emerged in the early 2000s but actually gained momentum only in the past few years, however we still do not get to see them in our daily life. It has generally been avoided by the mainstream market due to its cryptic nature which requires technical knowledge prior to its use. Lack of strong business model (by companies) and inability to adapt to new rapid changes (by consumers) are the two primary factors contributing to the fact that IoT is well ahead of its times but it need no longer be. In this paper, Ive created a setup for smart home that allows the users to control their electrical appliances from internet and even makes the appliances smart enough to react to the environmental conditions on their own. Using this setup, I observed the pattern in which electricity consumption and carbon footprints reduced as compared to the conventional setup i.e. without IoT. Analyzing this data provided me a solid proof that IoT definitely helps us to save electricity and environment. Since IoT is beneficial for all, I, then focused on the challenges that are hampering the penetration of IoT into the daily lives of consumers and how the consumer is overlooking the benefits that it has to offer, which even includes a primary concern for many, i.e. saving money. This paper is overall aimed to change the way a consumer thinks about IoT and to provide a solid ground to how it is beneficial.

Abstract: Internet of Things (IoT) will comprise billions of devices that can sense, communicate, compute and potentially actuate. The data generated by the Internet of Things are valuable and have the potential to drive innovative and novel applications. The data streams coming from these devices will challenge the traditional approaches to data management and contribute to the emerging paradigm of big data. One of the most challenging tasks before collecting and processing data from these devices (e.g. sensors) is discovering and configuring the sensors and the associated data streams. In this paper, we propose a tool called SmartLink that can be used to discover and configure sensors. Specifically, SmartLink, is capable of discovering sensors deployed in a particular location despite their heterogeneity (e.g. different communication protocols, communication sequences, capabilities). SmartLink establishes the direct communication between the sensor hardware and cloud-based IoT middleware. We address the challenge of heterogeneity using a plugin architecture. Our prototype tool is developed on the Android platform. We evaluate the significance of our approach by discovering and configuring 52 different types of Libelium sensors.

Abstract: Internet of Things is a novel concept that semantically implies a world-wide network of uniquely addressable interconnected smart objects. It is aimed at establishing any paradigm in computing. This environment is one where the boundary between virtual and physical world is eliminated. As the network gets loaded with hitherto unknown applications, security threats also become rampant. Current security solutions fail as new threats appear to de-struct the reliability of information. The network has to be transformed to IPv6 enabled network to address huge number of smart objects. Thus new addressing schemes come up with new attacks. Real time analysis of information from the heterogeneous smart objects needs use of cloud services. This can fall prey to cloud specific security threats. Therefore need arises for a review of security threats for a new area having huge demand. Here a study of security issues in this domain is briefly presented.
Conceptual Framework for Internet of Things' Virtualization via OpenFlow in Context-aware Networks  [PDF]
Theo Kanter,Rahim Rahmani,Arif Mahmud
Computer Science , 2014,
Abstract: A novel conceptual framework is presented in this paper with an aim to standardize and virtualize Internet of Things(IoT) infrastructure through deploying OpenFlow technology. The framework can receivee services based on context information leaving the current infrastructure unchanged. This framework allows the active collaboration of heterogeneous devices and protocols. Moreover it is capable to model placement of physical objects, manage the system and to collect information for services deployed on an IoT infrastructure. Our proposed IoT virtualization is applicable to a random topology scenario which makes it possible to 1) share flow sensors resources 2) establish multioperational sensor networks, and 3) extend reachability within the framework without establishing any further physical networks. Flow sensors achieve better results comparable to the typical sensors with respect to packet generation, reachability, simulation time, throughput, energy consumption point of view. Even better results are possible through utilizing multicast groups in large scale networks.

Computer Science , 2011,
Abstract: This paper focuses on the characteristics of two big triggers that facilitated wide user adoption of the Internet: Web 2.0 and online social networks. We detect brakes for reproduction of these events in Internet of things. To support our hypothesis we first compare the difference between the ways of use of the Internet with the future scenarios of Internet of things. We detect barriers that could slow down apparition of this kind of social events during user adoption of Internet of Things and we propose a conceptual framework to solve these problems.

Sensors , 2013, DOI: 10.3390/s131115582
Abstract: The Internet of Things (IoT) is a networking paradigm where interconnected, smart objects continuously generate data and transmit it over the Internet. Much of the IoT initiatives are geared towards manufacturing low-cost and energy-efficient hardware for these objects, as well as the communication technologies that provide objects interconnectivity. However, the solutions to manage and utilize the massive volume of data produced by these objects are yet to mature. Traditional database management solutions fall short in satisfying the sophisticated application needs of an IoT network that has a truly global-scale. Current solutions for IoT data management address partial aspects of the IoT environment with special focus on sensor networks. In this paper, we survey the data management solutions that are proposed for IoT or subsystems of the IoT. We highlight the distinctive design primitives that we believe should be addressed in an IoT data management solution, and discuss how they are approached by the proposed solutions. We finally propose a data management framework for IoT that takes into consideration the discussed design elements and acts as a seed to a comprehensive IoT data management solution. The framework we propose adapts a federated, data- and sources-centric approach to link the diverse Things with their abundance of data to the potential applications and services that are envisioned for IoT.

International Journal of Information and Network Security (IJINS) , 2012, DOI: 10.11591/ijins.v2i1.1234
Abstract: Considering the popularity of Internet of Things, this paper discusses the management problem of Internet of Things from the viewpoint of “Management as a Service”, and proposes a service-oriented management solution for Internet of Things. This paper then introduces RESTful Web Services into service-oriented management for Internet of Things, and demonstrates the definition of service-oriented management information based on YANG using JSON and service-oriented management operations by means of REST. The case study for cooperative management of campus security in the Internet of Things environment shows that, the proposed approach has a management-tolerant resource cost and a suitable performance of service-oriented management for Internet of Things.

Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.34014
Abstract:

In order to incorporate smart elements into distribution networks at ITELCA laboratories in Bogotá-Colombia, a Machine-to-Machine-based solution has been developed. This solution aids in the process of low-cost electrical fault location, which contributes to improving quality of service, particularly by shortening interruption time spans in mid-voltage grids. The implementation makes use of MQTT protocol with an intensive use of Internet of things (IoT) environment which guarantees the following properties within the automation process: Advanced reports and statistics, remote command execution on one or more units (groups of units), detailed monitoring of remote units and custom alarm mechanism and firmware upgrade on one or more units (groups of units). This kind of implementation is the first one in Colombia and it is able to automatically recover from an N-1 fault.

Social Technologies , 2012,
Abstract: Purpose: To define the Internet of things and to analyze it as a background for the internet of services.Design/methodology/approach: The article discusses potential possibilities and problematic issues concerning the Internet of things (IoT) and Internet of services (IoS). The debates concerning IoT and its possible application fields have continued for more than ten years. The technological background is there and the fields of application are broad. However, there is still a lack of understanding about the possible benefits that technology could give to various bodies if applied correctly. This article is based on comparison and analysis of scientific articles, research papers and case studies related to the potential for IoT and its implementation in IoS.Theoretical findings: IoT is a logical evolutionary step for the internet. Despite the technological background, the concept of objects which are aware of their surroundings, allow to manipulate them by defining different rule patterns and ensuring interaction possibilities with other objects or human beings. The necessity for web-based services is increasing along with the technological gadgets which support them. Applying things, which are connected in a network, could revolutionize many industry and service sectors and create new service provision and administration methods based on information technology. However, there are many problematic issues and research challenges related to the IoT. Few of the most significant are related to standardization of technology, legal regulation and ethical aspects concerning the IoT technology.Research limitations/implications: The IoT is a popular trend promoted by the business sector and governmental bodies. There are few comprehensive studies and projects which talk about the benefits that business and society could gain from the IoT. There is a lot less information about the possible risk and problematic aspects, and a lack of agreements between the developers of technologies. In the scientific community arguments are also varied depending on the technologies used and regulation models adopted. For that reason it is possible to review the topics only focusing on narrow, but most comprehensively analyzed spectrum of problematic issues.Practical implications: Theoretical framework for future research in the field was developed.Keywords: internet of things, internet of services, future internet.Research type: conceptual paper.
