Automation of modern industrial plants require real-time tracking of object locations and sensing of local and ambient parameters for variety of applications such as counting and tracking of objects in assembly line, detection and positioning of failures of machines etc. Mostly, discrete Real Time Location System (RTLS) performs object tracking in existing industrial automation without its integration...
Wireless Sensor Network (WSN) acts as one of the fundamental elements of network infrastructure, requiring to establish a wireless communication network for the reliable frame transmission. The channel access in IEEE 802.15.4 employs Carrier Sense Multiple Access with Collision Avoidance (CSMA) without amendment. However, the contention collision of typical technique, IEEE 802.15.4, could not guarantee...
Event detection has become a ubiquitous application in the domain of wireless sensor networks. In any distributed event detection system, duplicate event data that can increase the likelihood of network congestion is a primary concern, and in-network data aggregation is a popular approach to alleviate this problem; similarly, duplicate data can be discarded. We propose a novel approach that utilises...
The article presents an analysis of correlation-based clustering procedure in cooperative spectrum sensing. The motivation is to assess if it is more beneficial in terms of energy efficiency to group nodes according to the received signal-to-noise ratio (SNR) on the link between Primary User and node or according to the distance between nodes. To this end, a merged clustering measure is introduced...
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...

A key success factor for a smart grid lies on reliable data exchange between components across domains in the grid. However, a smart grid involves various types of devices and equipment having different quality concerns and computing capability, which requires a flexible communication platform that can accommodate heterogeneous devices. The Data Distribution Service (DDS) is a standard for data-centric...
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...
In cognitive radio networks (CRNs), spectrum sensing data falsification (SSDF) is one of the most typical attack which hugely degrades the detection performance of cooperative spectrum sensing (CSS). SSDF and defense strategies have been an active field of research, but countermeasures of existing researches are sensitive to the number of malicious users (MUs). In this paper, we propose a two-stage...
Reliability is an important research issue in wireless sensor networks(WSNs).

Multiple routing metrics have been proposed for maximizing throughput or guaranteeing reliable delivery of the data. Some of the most common used metrics, neglect the bursty behavior of the channel. A new metric improve this by taking burstiness into account. This creates a burst estimation of all links and allocates the maximum number of required slots in worst-case. Even though this is a solution...
