The general structure and main principles of creating a multi-version post-severe NPP accident monitoring system, which consists of one wired and three drone-based wireless network subsystems, are proposed. Reliability block diagrams for the system are built. On the basis of the reliability block diagrams, reliability models of the system are developed. The dependence on probability of failure-free...
The paper presents the design and implementation of an integrated wireless network that support to the multiparametric geophysical monitoring network of the Campi Flegrei volcanic area. The wireless network is equipped with a tool for real-time monitoring and fault detection. The enhancement of the transmission system with respect to the previously existing one has been realized in view of the increased...
Infrastructure monitoring is an important class of wireless sensor network (WSN) applications. When the topology of a WSN designed for infrastructure monitoring is linear in nature, such as bridges, highways and pipelines, this kind of WSN is known to be linear WSN (LWSN). To achieve the high-reliable infrastructure monitoring services, hybrid LWSN has been designed where a limited number of support...
Now a days wireless sensors are attracting strong interest for different monitoring and controlling applications as they are integrated with the function of sensing, processing and wireless communication. The wireless sensor networks have been deployed for agricultural, industrial, remote monitoring and traffic management purposes. As energy shortage is a worldwide problem so that more attention has...

The demand for wireless sensor networks (WSNs) applied to industrial process monitoring and control should increase as the forth industrial revolution gathers pace. Flexibility and low cost make them the perfect choice for the modern 21st century manufacturing plants. In this paper we describe the tests done with a WSN in an industrial environment and analyze the results to ascertain how much interference...
A Linear Wireless Sensors Network (LSN) is a sensor network model used for monitoring linear structures such as oil, gas, and water pipelines. This type of network depends on the information sent from one node to another in a sequence. As a result, a failure or attack that occurs at any node may isolate some nodes from the network, which will affect the reliability of the entire network. In this situation,...
While using Wireless Sensor Network for monitoring the remote patient's health situations, data related to that patient is stored in the sensors and the huge amount of data results in buffer and link overflow. The buffer and link overflow causes the problem of congestion which results in loss of packet and transmission delay. Congestion is a situation in which buffer overloaded with excessive data,...
A smart grid is a modernized power grid. Many novel technologies have been used to smart grids. One of the technologies is the wireless sensor network. In this study, a novel backbone communication network is proposed, which combines two different wireless technologies (the ZigBee and Wi-Fi protocol), to form a communication network between the transmission towers in a power grid. The gateway in the...
Industrial wireless sensor networks (IWSNs) have become popular, given the lower cost of installation than wired networks and their flexibility. WSNs are applied in monitoring, measurement, and control. Nuclear power plants (NPPs), in particular, have not been eager to adopt WSNs due to reliability, electromagnetic and radio frequency interference (EMI/RFI) as well as security concerns. On the other...

Linear Wireless Sensor networks (LSN) are used to monitor long linear critical structures such as pipelines, rivers, railroads, international borders, and high power transmission cables. Due to the importance of these structures, the LSN must be designed with high reliability considerations. However, one of the main challenges of LSN design is the connection reliability among the nodes. Unlike in...
Application communication in wireless sensor networks (WSN) depends on two important factors: acquisition of sensed data from a specific area, and network connectivity that concerns the reliable delivery of the observed data from sensor nodes to the sink node. In this paper, we consider the application communication reliability (ACR) of WSN supporting K-coverage in the presence of shadowing for a...
Wireless sensor networks (WSNs), now-a-days, are deployed in environmental data collection as well as in critical event monitoring. Successful data collection requires reliability while reliable event detection necessitates timeliness. Simultaneous data gathering and event monitoring is not well studied in literature.

Wireless Body Area Networks (WBANs) offer tremendous benefits for remote health monitoring and real-time patient care. However, the success of such a system would primarily depend on the reliability of the data transmitted by the WBAN. Two aspects of data reliability need to be considered, namely, data accuracy and data freshness (or, recentness of data). Assuming that the sophistication of the sensors...
