The recent enhancement of sensor devices, such as the Micro-Electro Mechanical Devices (MEMs) used for information collection and dissemination, has led to the emergence of the Internet of Things (IoT). This new paradigm overlaps with many research area such as the Wireless Sensor Networks (WSNs) where sensor nodes are deployed over an area to perform local computations based on information gathered...
In the recent years, mobile wireless technology has invaded the computer domain with the increased evolution of mobile devices in computing power, storage capacity, and other richer functionalities. Those devices are no longer restricted to phone calls and messages, but also for the access to internet (via WiFi, 3G, 4G …) and exchanging data via Bluetooth. On the other side, we have the great success...
Wireless Sensor Networks (WSNs) are getting popular day by day. But due to the constrained of resources and limited battery supply of sensor nodes, this becomes the major areas of research. Earlier the LEACH protocol proposed contributes a lot in terms of reducing energy consumption among sensor nodes. Later on concept of rendezvous nodes (RZ) and mobile sink was combined with LEACH to reduce energy...
Simultaneous wireless information and power transfer (SWIPT) is an effective way for energy-constrained unmanned aerial vehicle (UAV) to prolong the network lifetime. In this paper, an amplify and forward (AF) relaying network is considered, where an energy-constrained UAV harvests energy and information simultaneously from base station and then transmits the information to the destination node. Based...
Explosion of mobile traffic will bring a heavy burden to the core network, and rapid growth of mobile devices, as well as increasing demand for delay-sensitive services poses severe challenges to future wireless communication systems. In this regard, local breakout is a promising solution to save core network load and, more importantly, to reduce end-to-end (e2e) delay of packets with local significance...
This paper describes a prototype implementation of a wireless sensor network allowing for the application of the Industry 4.0. concept. It discusses both the requirements for wireless sensor networks for industrial applications as well as ways of their development. Operating modes of wireless sensor network elements enabling implementation of the indicated requirements are described in detail. Authors...
IEEE 802.16m, aiming at providing secure communication pathways between the base station (BS) and the mobile station (MS), is a broadband wireless MAN (Metropolitan Area Network) standard. Its security sublayer contains a Privacy Key Management (PKM) protocol, which achieves authentication and key management in the communication process. In this paper, we apply Communicating Sequential Processes (CSP)...
This paper contributes to recent improvements in energy-efficient clustering algorithms for static and homogeneous wireless sensor networks. We propose a modified algorithm, called NREC, which considers information on the locally normalized residual energy of sensor nodes. This information is weighted with the probabilistic threshold used in standard algorithms for periodic election of cluster heads...
Low-Power Wide-Area networks promise to deliver limited IoT payloads reliably at distances in excess of 10 km raising the possibility of thousands of IoT devices connected to a single base station. PlanIt is a web application able to visualize connectivity in these large-scale deployments prior to deploying hardware or even making a single signal-strength measurement. DQ-N is an adaptation of distributed...
Sensor networks have been widely used traditionally in monitoring the state of heavy machinery and large factories whose condition is critical to the operation of machine as well as the safety of people around them. Recently, industrial wireless sensor networks (IWSNs) are getting popular for environment monitoring in such conditions to help us make a decision on the state of machines in a certain...
Wireless Sensor Networks have been known and used for a long time, but as time passed they started to improve and generate more interest from end users. As the attention increased, so did the attacks on these, due to their limited capacities and methods to employ an efficient protection. The key interest for current research teams is to develop methods to protect data without impacting the communication...
This paper discusses the role that resource pooling and cooperation may play in reducing the ever-growing power consumption of cellular networks. These two abstractions are often referred to as methods to enhance communication throughput and increase data transmission resilience. The goal of this work is to advocate and highlight that they can also represent effective directions to go through in order...
We consider secret-key generation between several agents and a base station that observe independent and identically distributed (i.i.d.) realizations of correlated random variables. Each agent wishes to generate the longest possible individual key with the base station by means of public communication. All keys must be jointly kept secret from all external entities. We do not require them to be kept...
Wireless sensor network is a set of independent transducers with communication infrastructure for recording and monitoring at different locations. The monitoring parameters are energy, temperature, humidity, pressure, direction and speed of the node in the WSN. The main challenges of WSN are efficiency, scalability, heterogeneity, reliability, robustness, privacy and security. Many researchers are...
We present the design of a suite of protocols for wireless sensor networks (WSNs) with respect to a complete life cycle of a WSN node from warehouse to the end of operation. While there are numerous publications on various, usually isolated, aspects of WSNs, the whole life cycle of a node from registration in an automation system via warehouse, calibration, mounting, performing measurements to finally...
Wireless Power Transfer (WPT) is an attractive technology because it can supply power to IoT devices where battery replacement is difficult or the maintenance cost is high. Polarization Switching WPT antenna (PS-WPT antenna) is proposed in this paper. The polarization switching characteristic makes this design a good candidate for 5G-IoT sensors powered by using wireless power transfer. The 3GPP had...
WSN(Wireless Sensor Network) is an application specific network. There is no general optimized solution for WSN problems. It depends upon application, resource availability. Structural health monitoring (SHM) using wireless sensor networks has drawn considerable attention in recent years. It is an active area of research that can autonomously and proactively assess the structural integrity of buildings,...
Radio signals are used to transfer data between two or more physical devices in wireless networks. These devices are generally called as “nodes” of the network. In wireless ad-hoc networks, nodes do not depend on any pre-existing infrastructure. In these communications depends on the capability of the nodes to make a multi-hop radio network. Security is a major concern in every communication system...
A new centralized clustering protocol for periodic traffic wireless sensor networks is proposed in this paper. The proposed protocol uses one-step off-line cluster computation algorithm, where all the clustering schemes and their respective durations are calculated by the base station (BS) once at the network initialization. This provides the BS a global vision and enables it to reach better clustering...
The coming generations are using the wireless sensors, and all of these networks have been deployed across various areas. Also they are used with the real time systems thus catering to the needs of the present scenario which the traditional methods have failed. These wireless networks deploy sensors around the area, but the disadvantage lies that these sensors have very limited battery life, so to...
