This paper presents a multi-layer distributed performance management model for Internet of Things (IoT) as a service for caregivers. Performance monitoring and control of IoT devices and services are vital functions for e-health systems. Cloud-based IoT systems with centralized data centers further underline the need for distributed management. The main contribution of this paper is a model and prototype...
The remote monitoring and control of machines are essential in industrial environments. Emerging communication technologies such as Web of Things and Machine to Machine Communication can meet this demand for automation in Industry 4.0. This paper aims to introduce a solution for continuous and remote monitoring of electrical quantities in smart industrial environments with three-phase systems. The...
Internet of Things (IoT) can be perceived as enabling user-specific interoperable communication services by integration of sensing and actuation technologies with other leading technologies, such as telecommunication, networking, security and cloud computing etc. Application of the ubiquitous IoT technologies to augment healthcare systems inadvertently exposes the latter to unpredictable, disruptive...
The Internet of Things (IoT) consists of all kinds of sensors which collect much information. The privacy and anonymity in IoT is fundamental to the system and must be resolved. Sima proposed a protocol about lightweight authentication and key agreement and claimed to be secure and robust against all existing methods of attack. In this paper, the author points out the vulnerability of Sima's protocol...
The number of connected Internet of Things (IoT) devices was about 8.9 billion in 2012 and it is statistically estimated to grow up to 50 billion devices in the beginning of 2020. The security of the IoT plays an important role in the correct and advantageous functionality of the interconnected devices. For efficiency considerations, some of the IoT data processing is optimal to be implemented in...
The Internet of Things (IoT) enables several heterogeneous devices, sensors, wearables, appliances and many other objects to inter-communicate and provide support for heterogeneous services. An IoT network needs to enable exchange diverse data types including multimedia and sensor data and be capable of handling a large number of IoT objects offering services at high quality levels. This paper proposes...
One of the crucial challenges in the recently emerging Internet of Things (IoT) applications is how to handle the massive heterogeneous data generated from a large number of resource-constrained sensors. In this context, cloud computing has emerged as a promising paradigm due to its enormous storage and computing capabilities, thus leading to the IoT-Cloud convergence. In such a framework, IoT devices...
With the advent of Internet and computational era, not only opportunity to send and receive data between humans, but also among the devices without human control over it. This is known as Internet of Things (IoTs) concept which can be applied for solving the growing issue of power/energy management. A solution is a cheap and easy to implement and manage energy monitoring system for our daily usage...
Wireless sensor network is one of the effective tools for data gathering in a variety of environments which has a lot of challenges. Controlling the congestion is one of the challenges that primarily depends on the way the large number of sensors in a network are organized and controlled. A group of nodes is called a cluster which sends information to the gateway through the cluster head. This structure...
Despite many Internet of Things (IoT) Infrastructures having been implemented in recent years, none of them is truly prepared for a global deployment, where failure tolerance and scalability are an essential requirement. This article presents an alternative concept for IoT Infrastructures, which focuses on enhancing the traditional centralized architecture, usually operated by a single entity, into...
Wireless sensor networks (WSNs) are extensively used in various industries and environments to monitor an environment and manage risks in situations such as real-time traffic monitoring and health care. The Internet of Thing (IOT) is a wireless sensor networks. Because a WSN is an open wireless communication network, it is vulnerable to security threats and attacks. It must authenticate its partner’s...
Wireless sensor networks (WSNs) include spatially allotted autonomous instruments that employ sensors to check environmental or physical conditions. These autonomous instruments or nodes blend with routers or gateway to make several WSN-based real-time applications. In many critical applications, an external user can directly access the real-time data from sensor node. In this context, before offering...
Internet of Thing (IoT) provide services by linking the different platform devices. They have the limitation in providing intelligent service. The IoT devices are heterogeneous which includes wireless sensors to less resource constrained devices. These devices are prone to hardware/software and network attacks. If not properly secured, it may lead to security issues like privacy and confidentiality...
Ambient Assisted Living (AAL) represents one of the most promising Internet of Things (IoT) applications due to its influence on the quality of life and health of the elderly people. However, the interoperability is one of the major issues that needs to be addressed to promote the adoption of AAL solutions in real environments. In this paper, an IoT prototype system for AAL called AAL-IoTSys is proposed,...
In the IoT world, establishing a strong mobile network architecture will be critical for organizations to bring together people, processes, data and things. Among the various available protocols and standards to network IoT entities, the Message Queue Telemetric Transport (MQTT) is already a reference solution. It provides a publish/subscribe messaging transport specifically designed to be used in...
Nowadays, the Internet of Things (IoT) is receiving more attention in commercial and academic research, especially about its security property. However, current protocols cannot satisfy the requirement of various IoT applications and introduce some problems. There are three typical problems: traditional public key infrastructure (PKI) apply in IoT will incur great overhead, wireless sensor network...
This communication allows the implementation of an internet of things solution for smart home. It uses the ZigBee network for communication within the home between the gateway and the different intelligent nodes. A PHP application has been developed enabling the user to control remotely his equipment locally or from the Internet. The house implemented is also characterized by a high degree of intelligence...
The Internet Protocol (IP) is ubiquitous in terrestrial and electromagnetic-carrier wireless networking. However, for very low-throughput underwater links (such as those using acoustic modems) the IP header introduces an unacceptable amount of data overhead for the small maximum transmission units available on underwater acoustic links. Nonetheless, it is becoming increasingly valuable to connect...
Emergency situations, such as fire incidents or terrorist attacks, have imposed strongest safety requirements for crowds gathering. The enhancement of situation awareness, decision support and emergency notification systems that facilitate the safety and effectiveness of evacuation processes in a major incident is therefore of utmost importance. ICT, IoT and smart systems have gained much attention...
Radio links in wireless body area networks (WBAN) experience highly time-varying attenuation because of topology instability. On the other hand, real-time, reliable, energy efficient and interference-aware communication protocol is the most important requirements of many WBAN applications. Since the channels quality is not stable, there is no any fixed optimal power level which meets all the requirements...
