LoRa is one of the most popular technologies for low-power wide area networks. It offers long-range communication with a low energy consumption, which makes it ideal for many applications in the Internet of things. The performance of LoRa networks depends on the communication parameters used by individual nodes. Several works have proposed differen...

Long Range (LoRa) is a low-power wireless communication technology for long-range connectivity, extensively used in the Internet of Things. Several works in the literature have analytically characterized the performance of LoRa networks, with particular focus on scalability and reliability. However, most of the related models are limited, as they c...

Long Range (LoRa) is a wireless communication standard specifically targeted for resource-constrained Internet of Things (IoT) devices. The number of LoRa-based networks is growing due to its operation in the unlicensed radio bands and the ease of network deployments. However, the scalability of LoRa networks suffers as the number of deployed devic...

The increasing demand for cellular network capacity can be mitigated through the installation of nomadic eNodeB, which serve a temporal increase of traffic volume in specific area. When nomadic cells are deployed, the transmission power of neighbour base stations needs to be optimised to limit the inter‐cell interferences. The authors analyse the p...

The increasing demand for cellular network capacity can be mitigated through the installation of nomadic eNodeB, which serve a temporal increase of traffic volume in specific area. When nomadic cells are deployed, the transmission power of neighbor base stations needs to be optimized to limit the inter-cell interferences. We analyze the problem of...
Conference Paper
As demand for mobile broadband grows, the need for greater indoor coverage and capacity becomes more urgent as the ubiquitous connection to the Internet is mentioned very often. Complementing macro capacity, small cells (femto-, pico-cells) offer a cost-effective way to meet this demand for complex indoor areas. Inspired by this increasing demand,...
Conference Paper
In this paper we present the Python LTE Software (PyLTEs), which is a open-source framework for performance evaluation and optimization of the configuration of LTE networks deployment. It allows to define the geographic location of cells, eNodeB configuration such as e.g. TX Power and spatial distribution of the clients. The soft-frequency reuse sc...
Conference Paper

Different architectures of interactions between the objects in the Internet of Things have been proposed, based on direct exchange of data between the wireless devices or based on synchronization with fixed network devices or cloud infrastructure. We evaluated how the selection of the communication architecture influences the performance of the dat...
Conference Paper

The operators are deploying heterogeneous networks with LTE base stations covering very small areas in locations with high bandwidth demand to address growing clients' needs. The femto cells and small cells are often installed indoor, to serve the clients of a single building, such as a shopping mall or an office building. In this paper we provide...
Conference Paper

The performance of SNMP, NETCONF and CWMP in LTE self-configuration scenario is investigated. The time required to perform the autoconfiguration of the LTE eNodeB is evaluated and a part of the LTE SON procedures. The influence of the size of the firmware file and the number of nodes being configured by a singe network management server is verified...
Conference Paper

We propose a novel method of transmit power selection to realize the Coverage and Capacity Optimization (CCO) function in LTE networks. We discuss how to use genetic algorithms to reconfigure the transmit power to realize the Self-Organized Network (SON) functions: maximize the network throughput offered to the clients and minimize the cost of the...

This paper compares the performance of three popular network management protocols: SNMP, Netconf and CWMP (TR069) applied to automate the configuration change and monitoring of wireless network equipment. The OMNeT++ discrete event simulator was used, with models of those three protocols. Two use cases were used for the evaluation: execution of a s...

We present an optimization method for automatic selection of downlink transmit power of LTE eNodeB based on the estimated throughput of the network. The procedures provide self optimized network functions to minimize the intercell interferences and maximizing the radio resource utilization. We propose a method based on the expected link throughput...

This paper proposes and analyses properties of transmission power control mechanism for Wireless Sensor Networks based on estimated packet reception rate. The algorithm is dedicated for low power wireless networks and its aim is to minimise average cost of radio transmission, reduce retransmissions and interferences between network nodes.
Conference Paper
Full-text available
Testing wireless sensor networks (WSNs) is not a trivial task, due to the massively-parallel communication between many independently running processors. Distributed way of operation does not allow step-bystep execution and typical debugging, so other techniques have to be used, such as detailed packet logging and analysis. We provide a 2-way WSNto...

Many theoretical works focus on maximizing the lifetime of a measurement-gathering sensor networks by researching different aspects of energy conservation or details of self-organizing network algorithms. In our practical deployment of such a network we learned that software and hardware reliability, as well as anticipation of worst-case scenarios,...

One of the most important characteristics of Wireless Sensor Networks is energy efficiency. Exhausted batteries cannot be easily replaced and cause connectivity problems and reduced network life. Therefore it is crucial to develop methods to reduce energy usage in those networks. In this work some methods in the MAC layer and network layer were tes...

Many theoretical works analysing Wireless Sensor Networks make ad hoc assumptions regarding their physical properties. In our work we measure physical properties of WSNs, such as node power consumption and effective error rates in many realistic scenarios, e.g. in open field, forest and urban environments. We use popular MicaZ and IRIS motes compli...

The increase in the number of devices that use wireless data transmission and the amount of data is causing the congestion in wireless networks. This project responds to this problem and aims to increase the efficiency of LTE, WiFi and heterogeneous networks and to reduce the cost of their construction and maintenance. In the project will be developed new algorithms for self-optimization and load balancing for wireless networks. Their introduction will significantly increase the bandwidth available for users by balancing of traffic in base stations and reduce deployment costs by using autoconfiguration mechanisms.
