The necessity to (re-)configure Internet of Things devices such as smart sensors during their entire lifecycle is becoming more important due to recent attacks targeting these devices. Allowing configuration parameters to be changed in any phase of a smart sensor's lifecycle allows security updates or new key material to be applied. Also, the functionality of a smart sensor can be altered by changing...
With high expansibility of sensor electronic devices, wireless sensor networks have attracted more and more attention. The k nearest neighbors (k-NN) query has become a significant part of sensor networks due to its availability and convenience. However, it is an important but challenging problem to keep privacy and security while still maintaining low energy consumption. In this paper, we address...
The Internet of Things (IoT) and cloud computing are the prime focus of the current research and development in all field of study. In this work, an attempt is made to enhance the integration of wireless sensor network (WSN) in IoT environment with cloud computing for health care system. IoT is a dynamic network infrastructure, that interconnects different sensor networks through Internet, acquire...
Considerable efforts have been expended on the centralised administration of WSNs. However, only very small functions, such as processing, memory, battery unit, and communication ability, can be configured using WSN nodes due to the associated resource restrictions. Moreover, unbalanced cluster construction and unbalanced energy dissipation can reduce network lifespan by a large extent. Therefore,...
There are billions of Internet of things (IoT) devices connecting to the Internet and the number is increasing. As a still ongoing technology, IoT can be used in different fields, such as agriculture, healthcare, manufacturing, energy, retailing and logistics. IoT has been changing our world and the way we live and think. However, IoT has no uniform architecture and there are different kinds of attacks...
Online education is evolving at a fast pace thanks to novel technology-mediated learning environments: Massive Open Online Courses (MOOCs), gamified learning, intelligent tutoring systems, citizen-science communities, informal learning groups are blossoming everywhere as novel opportunities for teachers and learners. However, the educational effectiveness of these solutions has to be proved and technological...
One of the main challenges in delivering end-toend service chains across multiple Software Defined Networking (SDN) and Network Function Virtualization (NFV) domains is to achieve unified management and orchestration functions. A very critical aspect is the definition of an open, vendoragnostic, and interoperable northbound interface (NBI) that should be as abstracted as possible from domain-specific...
Underwater sensor networks are bounded by data sensing, transmitting, and forwarding limitations. The transmitting of large volumes of data can require a large amount of time and power. This has led researchers to focus on the new technology of underwater computing systems, in which information is extracted under the water using embedded processors via data mining and/or data compression. In this...
This paper focuses on the theoretical modeling of sensor cloud, which is one of the first attempts in this direction. We endeavor to theoretically characterize virtualization, which is a fundamental mechanism for operations within the sensor-cloud architecture. Existing related research works on sensor cloud have primarily focused on the ideology and the challenges that wireless sensor network (WSN)-based...
In this paper, we design and implement the programmable nodes in software-defined sensor networks. Combining the emerging software defined networking (SDN) and the existing wireless sensor networks (WSNs), we propose an SDN-based sensor network architecture, called as software defined sensor networks (SDSN), which is composed of one centralized controller node, named as SDSN programmable controller...
Advances in microsystem technology have led to an increasing trend of cyber physical system integration into industrial environments for prognostic health monitoring. Harsh environmental conditions require wireless sensor nodes (WSNs) that are robustness and reliable whilst meeting the requirements of miniaturization, functional integrity and energy efficiency at the same time. Moreover design and...
Named Data Networking (NDN) is a new type of data-centric future internet architecture, and introducing security mechanisms into the architecture directly. However, in the process of verifying and transmitting data packets, there are still some issues of the sensitive information leakage. Aiming at the above problems, this paper proposes a sensitive information protection scheme using attribute-based...
This paper investigates a real-time water quality monitoring system by using a proposed brokerless publisher-subscriber (pub/sub) architecture framework. On the system, sensors sense the water measurement metrics, including temperature, pH, and dissolved oxygen level. All collected data are stored in a database and computed stochastically for further analysis on water quality. A complementary experiment...
By placing processing-capable devices at the edge of local wireless access networks, Edge Computing architectures have been recently proposed to connect mobile devices to computational power through a one-hop low-latency wireless link. In this paper, we propose a new design where edge assistance is used to control local data filtering at the mobile devices in bandwidth and energy constrained systems...
Recent years have witnessed tremendous growth in the number of smart devices, wireless technologies, and sensors. In the foreseeable future, it is expected that trillions of devices will be connected to the Internet. Thus, to accommodate such a voluminous number of devices, scalable, flexible, interoperable, energy-efficient, and secure network architectures are required. This article aims to explore...
The internet of things(IoT) and social networks is an important role of the internet of the future and used emerging techniques consist of heterogeneous communicating devices.

But the next decade, the internet will be connected physical devices and explore new way of working,...
In this paper, we propose a modular wireless sensor platform that consists of sensor modules. Each sensor module is a part of sensor system and in charge of one job in the system, such as computation, communication, output or sensing. Users can stack multiple modules together to build a unique sensor platform. Since users are able to easily replace one module with others, the proposed platform is...
We present a showcase of our SDN-inspired facility for the Internet of Things (IoT) — the CORAL (Cross-Layer Control of Data Flows) infrastructure. CORAL provides a hierarchy of network controllers that monitor network behaviour and adapts network protocol parameters on demand. It is built on top of rich network control abstractions and is hardware-independent. Our facility offloads protocol functionality...
Wireless Sensor Networks (WSNs) allow applications to interact with the physical world using nodes in an Internet of Things (IoT). Application level protocols such as the Constrained Application Protocol (CoAP) and data models such as IPSO Smart Objects and the Open Mobile Alliance Lightweight Specification (OMA LWM2M) have the potential to provide greater application interoperability and to ease...
The role of energy in wireless sensor networks (WSN) becomes very important when network is unattended and it is not possible to recharge sensor node's battery in the sensing region many times. Due to this limited battery energy of sensor nodes it becomes a challenge for WSN to maintain proper functioning for a long time. So for the enhancement in network lifetime of the WSN, here we propose a modified...
