Tytuł:: Design considerations for shallow water acoustic communication systems
Autorzy:: Yoon, Y.

Opis:: Relevant characteristics of the underwater channel used for acoustic communications are briefly described. There is a trade-off between achievable transmission range and data throughput. Transmission range of several kilometers with carrier frequency of 50kHz and several tens of kilometers with frequency less than 10 kHz might be possible using only 75 watts of acoustic power. Also, we investigated the required acoustic power for certain transmission ranges at given signal-to-noise ratio (SNR) values and the effect of wind speed. A shallow water channel model is proposed to study signal attenuation and arriving angles of the multipath. As the signal time delay increases, the arriving angle of the reflected signals becomes larger, allowing us to limit the number of multipath signals using a directional receiver. We will see that using directional receiver is better suited for a channel with a small range-to-depth ratio (RDR) and that equalization methods are better suited for a channel with a large RDR. Finally hardware complexity for designing shallow water acoustic communication systems is studied using a currently available digital signal processing (DSP) technology.

Opis:: Niniejszy artykuł omawia problematykę projektowania architektury bezpieczeństwa dla komunikacji pomiędzy użytkownikami końcowymi w sieci komputerowej. Szczególną uwagę zwrócono na zgodność mechanizmów odpowiadających za ochronę danych z zaleceniami międzynarodowej organizacji normalizacyjnej ITU-T (International Telecommunication Union). Przedstawione zostały metody ochrony danych oraz techniki, za pomocą których realizowana jest bezpieczna komunikacja. Opisane zostały dwie przykładowe architektury bezpieczeństwa: jedna, powszechnie używana w środowiskach sieciowych, i druga, będąca własną propozycją autorów. Omawiając przedstawione rozwiązanie, zwrócono dużą uwagę na wydajność obu systemów.
This paper introduces design considerations of a security architecture for network systems providing end-to-end communications. We present eight dimensions of a security architecture which is based on recommendations of International Telecommunication Union and a few security techniques that are often employed to protect against major security threats. We also present two examples of security architectures: the first of them is currently being deployed and exploited in production networks while the second is our own proposition.

Village Renewal Program
Opis:: The Program of Village Renewal stresses restoration of regional esthetic to village architecture and preserving or restoring elements of rural landscape. It suggests that apart from farm and habitable buildings themselves particular attention should be paid to so called common space, which includes greenery at the side of roads, road crossings, squares and car parks. Car parks in nowadays reality are an inseparable element of a housing estate landscape and village areas. Their shape is conditioned by building regulations and design norms, but the appearance of their surroundings is seldom an effect of the sense of esthetic from the designer. The esthetics of car parks in Polish villages varies but it is definitely far from ideal. It depends on the costs of their creation and maintenance and on the owner or administrator of the area. The Program of Village Renewal carried out by the Agricultural Academy in Wrocław together with Opole Marshal Office, which has the slogan "Let's care about our Landscape", promotes among inhabitants of villages the need of esthetically shaping the whole of the rural landscape. It stresses concern about commonly accessible places, particularly common areas which belong to the commune. It stresses the increasing esthetic benefits of those places and harmonic inscribing them in rural architecture. The answer to those needs are projects by Landscape Architecture students at our academy. Having done analyses and landscape studies and having elaborated the needs of local communities, they design conceptions for the creation of common areas revitalization for chosen villages. Those areas especially near commercial, administration, cultural, educational or sports objects, are enriched with a certain number of parking spots which are harmonically composed with the whole area and combined with a cover of greenery. It is important to provide rural car parks with ecological character, starting with lawn and concrete surface to freely grouped parking spots, for example in empty spaces under existing trees. Landscape architects who take care of those rural areas have a task to properly shape common areas in villages, including designing parking spots together with their surroundings. Creating them in such a way as to harmonically compose them in their rural landscape surrounding so they do not interfere by the oddity of their form and material with the regional architectural heritage and become a friendly and esthetical element of that landscape for the viewer.

Tematy:: ad hoc networks

Opis:: This paper deals with the tradeoffs between security, real-time and lifetime performance. Due to the multihop nature of communication wireless ad hoc networks are very vulnerable to attacks. Malicious nodes included in a routing path may misbehave and organize attacks such as black holes. Scaling the number of hops for a packet delivery we trade off energy efficiency against security and real-time communication. To study the multihop communication we propose a hierarchical communication model. The REWARD (receive, watch, redirect) algorithm for secure routing is employed as a main example for corrective actions. Symmetrical routing is a distinguish feature of protocols such as REWARD and we outline the threshold of conflict between power-efficient partitioning of communication links and symmetrical routing.

Opis:: The paper describes the application of the traffic engineering framework together with application layer procedures as mechanisms for the reduction of network latency lags. These mechanisms allow using standard and inexpensive hardware and software technologies typically applied for office networking as a means of realising networked control systems (NCSs) with high dynamic control plants, where a high dynamic control plant is the one that requires the sampling period several times shorter than communication lags induced by a network. The general discussion is illustrated by experimental results obtained in a laboratory NCS with the magnetic levitation system (MLS), which is an example of a structurally unstable plant of high dynamics.

Opis:: This paper presents a theoretical matrix analysis of antenna structure consisting of two double-element planar antennas for ultra-wideband (UWB) application in 2*2 MIMO indoor communication systems. The structure and characteristics of planar two-element UWB antenna are presented. Two matrix models of MIMO antenna system are represented in the paper. A standard MIMO signal transmission matrix without taking into consideration the coupling between antennas is described. A new approach to a full electromagnetic analysis based on the scattering matrix of the MIMO spatial antenna array is proposed. Functional power parameters for the whole MIMO UWB transmit-receive antenna structure are introduced. Results of computer simulations of different matrices describing a MIMO antenna system and the transmission propagation pulses are presented.

Opis:: A communication protocol is a set of rules defined formally that describes the format of digital messages and the rules for exchanging those messages in or between computing systems. The Internet Protocol Suite used for communications throughout the Internet uses encapsulation to provide a way of abstracting protocols and services. This abstraction is grouped into layers of general functionality. For protocols on the transmission layer, many choices exist. But while popular protocols such as TCP, UDP and SCTP do provide connection oriented communication offering reliability, ordering and data integrity, solutions that offer such connections from one point to multiple endpoints are still limited. TCP only supports point-to-point communication and SCTP offers multi-homing functionality, but the transmission is still limited to two logical endpoints. In this paper we use the simple, stateless, transmission model of UDP in order to provide TCP-like services for one-to-many communication that is not limited to just multi-homing or other particular solutions. The protocol supports reliable communication from one endpoint to multiple endpoints in different transmission modes. In order to make it easier for developers to customize the protocol to their needs and possibly extend/modify it in order to create new variants from it, the protocol is developed in user space. Because of this design restriction performance wasn't the main objective of our work, but rather the ease of customization and experimentation with new protocol variants. The protocol was implemented in the C++ programming language using classes with virtual members. New variants of components, such as packet retransmission, can easily be implemented without changing the whole code base.
