Wireless Sensor Network (WSN) is a particular network built from small sensor nodes. These nodes have unique features. That is, it can sense and process data in WSN. WSN has tremendous applications many fields. Despite the significance of WSN, this kind faced several issues. The biggest problems rising are energy consumption security. Robust security development needed to cope with applications...

Artificial intelligence (AI) and machine learning (ML) techniques have huge potential to efficiently manage the automated operation of internet things (IoT) nodes deployed in smart cities. In cities, major IoT applications are traffic monitoring, waste management, buildings patient healthcare monitoring. The small size based on low power Bluetooth (IEEE 802.15.1) standard wireless sensor networ...

Wireless sensor networks (WSNs) are fast evolving technology for collecting data in real time. Every wireless sensor network (WSN) is consisted of technical and software components which have to refer to the selected application. The paper focuses on the selection of WSN components. The WSN will be situated in the center of Olomouc City (OWSN). It will focus on measurements of harmful air pollu...

Since the nodes in Wireless Sensor Networks (WSN) are typically very small in size and are powered by irreplaceable battery, efficient use of energy becomes one of the most challenging tasks while designing any protocol for WSN. In this paper, we propose a routing protocol named Reliable and Energy Efficient Protocol (REEP) for WSN. The performance of REEP has been evaluated with the help of si...

Wireless Sensor Networks (WSN) are highly distributed self organized systems. WSN have been deployed in various fields. Because of some hardware problems, especially with respect to energy supply and miniaturization, WSN have certain short comings. This paper focuses on various issues such as routing challenges and design issues, topology issues and Quality of Service support issues associated ...

Heterogeneous wireless sensor network (heterogeneous WSN) consists of sensor nodes with different ability, such as different computing power and sensing range. Compared with homogeneous WSN, deployment and topology control are more complex in heterogeneous WSN. In this paper, a deployment and topology control method is presented for heterogeneous sensor nodes with different communication and se...

In recent times, there have been many advances in the field of information theory and wireless sensor network (WSN) technologies. Network coding is a new paradigm in data transport and promises to change many aspects of WSN. This paper proposes a network coding multipath routing algorithm in WSN (NC-WSN). It is typically proposed in order to increase the reliability of data transmission or to p...

In this paper, we propose a set of experiments for evaluating sensors’ precision in measuring received signal strength indicator (RSSI) in wireless sensor networks (WSN). More specifically, a WSN application is implemented for collecting RSSI measurements in different conditions. The application consists of two parts: an experiment control script which runs on a computer, and an experiment sens...

Debugging wireless sensor networks (WSN) is a notoriously hard problem. WSNs share the debugging problems of both embeddedand distributed systems. The result is that it is very hard to get an insight into the inner workings of a real-world WSN. We have designed the Monitored External Global State (MEGS) tool that recreates the global state of a WSN from debug output. With MEGS a developer can d...

The wireless sensor network has been gaining popularity in all fields. The applications of the WSN are traffic analysis, environmental monitoring, tactical systems, etc. Drawbacks of the WSN include limited battery power, limited bandwidth, memory constraint, etc. Hence designing an efficient MAC layer protocol for WSN is a challenging task. TDMA based MAC protocols can overcome the mentioned d...
