Opis:: Over the last few years, wireless sensor networks (WSNs) have started to play more and more important role in civil and military applications. A typical sensor network consists of resource-constrained sensing nodes, which monitor environment and send the data to more powerful gateway nodes. The goal of gateway nodes is to aggregate, process and send the data to other gateways or directly to sink nodes. The proper placement of nodes is needed to provide good network operation. Sensing nodes are often placed in a random manner unlike gateways. Gateways, due to their role and cost, are installed rather in a controlled way. In this paper, a bi-criteria gateway placement problem is introduced. The problem is shown to be NP-hard. We formulate it as a linear programming problem, then we develop the Multi-criteria Simulated Allocation (MSAL) heuristic algorithm, for the purpose of cost-effective gateway deployment and power-effective wireless connection management. Finally, we evaluate the efficiency of the algorithm by comparison with the exact method.

Opis:: The major challenge in designing wireless sensor networks (WSNs) is to find tradeoff between the desired and contrary requirements for the lifetime, coverage or cost while coping with the computation, energy and communication constraints. This paper examines the optimal placement of nodes for a WSN. It is impossible to consider the deployment of the nodes separately from WSNs applications. We highlight the properties of WSNs applications that determine the placement problem. We identify and enumerate the various objectives that should be considered. The paper provides an overview and concentrates on multi-objective strategies, their assumptions, optimization problem formulation and results.

Opis:: The paper describes an idea and realization of a system for collecting and processing data from different types of wireless distributed sensors. The system consists of wireless sensor networks. Each network consists of a server connected to the Internet and theoretically unlimited number of clients. The described server has been built with two types of microcomputers. It provides tools for data collecting and processing. A client, described in Section 5, can be implemented on any PC (Personal Computer) with Windows or Linux including the Raspberry PI and any other microcomputer with HDMI joint. It allows providing an interactive signboard. The data coming from a wireless measuring unit is stored in the server. Two versions of the measuring unit (Section 6) were developed. They differ in wireless modules (compared in Section 2). The first solution uses XBee-PRO 868. The second one uses CC-2530 working in ISM 2.4GHz band. The coverage comparison of both solutions is presented in Section 7. The system can be adjusted to measure any environmental value starting with temperature, humidity and ending with more advanced like the chemical composition of air. There is also included comparison with existing commercial solutions.

Opis:: The paper describes an idea and the realization of a remote reading water meters system with wireless pictures transmission to the mobile server. The system consists of various water meters with installed electronic devices for measurement capturing. The measurements are read by taking a picture of the analog number indicators from the front panel. The pictures are send wirelessly to the mobile server which stores them until the acknowledgement from the main server is received. The mobile server is constructed of the microcomputer Raspberry Pi 3 connected with the XBee_PRO through adapter. The pictures transmission from the mobile server to the main server is realized by the Internet connection. The main server application allows recognizing the numbers from received pictures. The measurement data is available as digital numbers in a data base of the main server. The designed system is dedicated to the work in a low population density area.

Opis:: Formation control is an important part of any system that utilizes multiple mobile agents to achieve its parti‐ cular goals. One of those applications is the mobile wi‐ reless network sensor. This field has become increasingly more popular in recent times due to the advancement of technology, especially in the fields of miniaturization and telecommunications. The main problem of this research is the relatively untested sensing capability of a mobile wireless sensor network in an operating area that has dis‐ tributed and/or multiple locations of high interest. The purpose of this research is to discover the compatibility of a multiple‐agent coverage control system with several examples of interest functions that have multiple and/or distributed points of global maximum value in order to explore more thoroughly the performance of a given sy‐ stem in a varying environments.

Opis:: Bezprzewodowe sieci sensoryczne (BSS, ang. WSN) są coraz częściej stosowane do obserwowania czynników środowiskowych (zastosowania militarne i cywilne). Dzięki postępowi technologicznemu możliwe jest obecnie wytwarzanie węzłów o wymiarach rzędu centymetrów i w cenie poniżej kilku USD za sztukę. Pozwala to na stosowanie węzłów sensorycznych na niespotykaną dotąd skalę i otwiera nowe możliwości dla tzw. wszechobecnej komputeryzacji życia (ang. pervasive/ubiquitous computing). Początkowo, sieci sensoryczne były rozwiazaniami przewodowymi. Rozwój technik bezprzewodowych i przetwarzania danych (procesory, algorytmy, etc.) pozwolił na objęcie przez węzły sensoryczne większego terenu badań. Kolejnym krokiem było zmotoryzowanie bezprzewodowych sieci sensorycznych poprzez montaż węzłów na poruszajacych się pojazdach, co pozwoliło na jeszcze większą rozdzielczość obrazowania przy praktycznie takich samych nakładach finansowych. Artykuł ten jest wprowadzeniem w obszar bezprzewodowych i mobilnych sieci sensorycznych.
Wireless sensor networks (WSN) are used to monitor strategic (from the public safety point of view) parameters of air pollutions. Technological progress in the area of sensor networks allows manufacturing centimetre-scale sensor nodes that may cost less than a few USD per piece. This enables using sensor nodes at such a scale allowing for ubiquitous computing. Initially, the sensor networks were wired solutions. Development of wireless data processing technologies (processors, algorithms, etc.) enables to monitor much larger area compared to wired solutions. The next natural step of sensor network development was to enable mobile monitoring by mounting sensor nodes on moving vehicles, i.e. allowing for much better sensor data resolution at virtually the same cost. This article is an introduction to issues of wireless and mobile sensor networks.

Opis:: Ubiquitous sensing enabled by Wireless Sensor Network (WSN) technologies cuts across many areas of modern day living. This offers the ability to measure, infer and understand environmental indicators, from delicate ecologies and natural resources to urban environments. The proliferation of these devices in acommunicating – actuating network creates the Internet of Things (IoT), wherein sensors and actuators blend seamlessly with the environment around us, and the information is shared across platforms in order to develop a common operating picture (COP). Fuelled by the recent adaptation of a variety of enabling wireless technologies such as RFID tags and embedded sensor and actuator nodes, the IoT has stepped out of its infancy and is the next revolutionary technology in transforming the Internet into a fully integrated Future Internet.

Opis:: The recent decades have seen the growth in the fields of wireless communication technologies, which has made it possible to produce components with a rational cost of a few cubic millimeters of volume, called sensors. The collaboration of many of these wireless sensors with a basic base station gives birth to a network of wireless sensors. The latter faces numerous problems related to application requirements and the inadequate abilities of sensor nodes, particularly in terms of energy. In order to integrate the different models describing the characteristics of the nodes of a WSN, this paper presents the topological organization strategies to structure its communication. For large networks, partitioning into sub-networks (clusters) is a technique used to reduce consumption, improve network stability and facilitate scalability.
