Abstract

Nowadays control and management logistics solutions that are used in terminals apply sensor based technologies to identify and localize containers in the yard. Nevertheless, because of the limits in the existing sensor technical specification, the position of nodes is still affected by some errors or sometimes it cannot be determined in real-time systems due to battery fall.

The sensor nodes pertaining to information storage and processing are mainly equipped with an uninterrupted power supply, independent distribution network connectivity and low performance computing system. The capacity of data traffic near a coordinator node is much higher than in the distant points; as a result, the existing elements close to processing nodes faster than others stop operating due to a lack of electricity and, as a result, the network ceases its overall work.

The article describes the modification of network routing protocols for energy balancing in nodes, using the mobility of the coordinator node, which provides dynamic network reconfiguration possibilities.

Abstract

In the recent years, low power computing systems have gained popularity. Networks, which use low power computer systems and transmit data by using wireless connection, are called wireless sensor networks. Nowadays, the most topical studies are aimed at grouping wireless sensor networks by the new optimisation of structure of network transmission protocol, the routing optimisation in a transmission network, optimisation of network structure, as a result of which it is possible to increase the life cycle of wireless network sensors.

There are a number of methods that allow solving this problem. These include the choice of the capacity of individual battery, the deployment of the node density, the adjustment of power transmitter, the application of energy-efficient data transfer protocol, positioning of network nodes and other methods that are associated with the introduction of additional network costs.

The present article discusses a new method for balancing energy through the mobility of network node intellectual agent, which provides the opportunity for reconfiguration of dynamic network or change of network topology.

Abstract

The general problem of wireless sensor network nodes is the low-power batteries that significantly limit the life expectancy of a network. Nowadays the technical solutions related to energy resource management are being rapidly developed and integrated into the daily lives of people. The energy resource management systems use sensor networks for receiving and processing information during the realia time. The present paper proposes using a coordinator role mobility method for controlling the routing processes for energy balancing in nodes, which provides dynamic network reconfiguration possibilities. The method is designed to operate fully in the background and can be integrated into any exiting working system.

Further Development of Information Technology Transfer Concept for Adaptation and Exploitation of European Research Results in the Baltic Sea Region Countries

This paper describes further development of information technology transfer concept for adaptation and exploitation of European research results in the Baltic Sea Region (BSR) countries. Riga Technical University (RTU) and Vilnius University (VU) as the partners of BSR Interreg Programme project BONITA (Baltic Organisation and Network of Innovation Transfer Associations) participate in the research which aims to develop a generic innovation & technology transfer concept (ITTC) to improve the collaboration between academia and industry. Particular attention in the paper is paid to the successfully proven concept of small and specialized exhibitions (the so-called "showrooms") run by technology suppliers and technology transfer facilitators. The creation of the distributed multi-organisational showroom-network environment in the framework of BONITA project for the purpose of technology & innovation transfer improvement is described.
