Запропоновано ієрархічну архітектуру сенсорної мережі (MESH-мережі) з високим ступенем масштабованості. Досліджено можливості її реалізації у режимі самокон- фігурування з використанням спеціальних маршрутних протоколів маршрутизації – за запитом (AODV) та з фіксованим зв’язком (OLSR). Показано, що у разі застосування механізмів адаптивного настроювання підвищується продуктивність цих протоколів порівняно з проаналізованими базовими протоколами. In this paper, the hierarchical architecture of the sensor network (MESH-network) with a high degree of scalability is proposed. The possibilities of its realization in the mode of selfconfiguration using the special routing protocol at the query (AODV – Ad-hoc On-Demand Distance Vectorisation) and fixed-line routing protocol (OLSR – Optimised Link-State Routing) are investigated. The comparative analysis of radiosensors networks that function after the algorithm of mobile agents, and networks that function after the algorithm of mobile agents with directed diffusion of data stream from knots-sources to the knot receiver, is executed. It is shown that for applications, where the energy consumption has a primary importance using of mobile agents with the directed diffusion allows considerably to prolong the life cycle of network. Technologies of mobile software agents with optimisation modules and autoconfigurations increase network bandwidth, reduce transmission delay and load on the network, reduce the traffic of HELLO messages in accordance with the scalability of the network. On the basis of theoretical estimates and simulation results, it can be concluded that the application of adaptive tuning mechanisms increases the performance of the protocols OLSR and AODV in comparison with the analysed basic protocols. The developed methods allow to create the mechanism of diminishing of loading on the separate links of network due to balancing of packages at a decision-making about routing. In theory it is possible to use offered approach for a decision-making about routing of packages in a network on the stack of TCP/IP protocols. more...

Інформація стає найважливішим національним ресурсом, відмінною рисою якого є те, що він не тільки не зменшується, а навпаки, – збільшується (передусім у разі обміну даними), якісно удосконалюється й разом з тим сприяє найраціональнішому використанню усіх інших видів інформаційних ресурсів. Під час передачі дуже важливо в кожному кодовому слові упаковувати більшу кількість інформації, тобто збільшувати ентропію. У роботі запропоновано алгоритм синтезу кодових слів у двійковому каналі з ентропією, що перевищує в десятки разів тривалість сигнальної конструкції. Transmission and perception of information are based on property of matter – reflection. Reflection is objective material process as a result of which system “A” interacting with system “B” reflects its image by change of the properties or acquires the new properties connected to closeness of system “B”. Therefore, the content of reflection is defined by features of the displayed system “B”, and the form of reflection – change of properties of the perceiving system “A”. Thus – information represents the internal content of process of reflection of one material objects in the form of change of properties of other objects. Information transfer is best of all estimated by development of the communications industry which is characterized by four features. The first feature is defined by specifics of the created product, namely – absence in case of information transfer of the material carriers of production. The second feature of communication is tightly connected to the first, is defined by the fact that implementation process of communication services and their consuming is not timeshared. Taking into account this feature the end result of production activity of branch – the service, cannot be in reserve, for example, in a warehouse. The third feature is that in the production process of the communications industry, information as an object of the labor, shall be subject only to spatial relocation, that is change of its location. The fourth feature is that information transfer process always is double-sided, that is occurs between the sender and the receiver of information. At the same time information becomes the major national resource which distinctive feature is that it not only does not decrease, and, on the contrary, – increases (generally in case of a data interchange), is qualitatively enhanced and at the same time promotes the most rational use of all other types of information resources. In the course of spatial relocation it is very important to pack bigger amount of information in each code word, that is to increase an entropy. In operation the synthesis algorithm of code words in the binary channel with the entropy exceeding duration of signal construction in tens of times is offered. more...
