Available in PDF, EPUB and Kindle. Book excerpt: Computer communication networks have come of age. Today, there is hardly any professional, particularly in engineering, that has not been the user of such a network. This proliferation requires the thorough understanding of the behavior of networks by those who are responsible for their operation as well as by those whose task it is to design such networks. This is probably the reason for the large number of books, monographs, and articles treating relevant issues, problems, and solutions in this field. Among all computer network architectures, those based on broadcast mul tiple access channels stand out in their uniqueness. These networks appear naturally in environments requiring user mobility where the use of any fixed wiring is impossible and a wireless channel is the only available option. Because of their desirable characteristics multiple access networks are now used even in environments where a wired point-to-point network could have been installed. The understanding of the operation of multiple access network through their performance analysis is the focus of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Broadcast media, such as satellite, ground radio, and multipoint cable channels, can easily provide full connectivity for communication among geographically distributed users. One of the most important problems in the design of networks (referred to as packet broadcast networks) that can take practical advantage of broadcast channels is how to achieve efficient sharing of a single common channel. Many multiple access protocols, or algorithms, for packet broadcast networks have been proposed, and much work has been done on the performance evaluation of the protocols. A variety of techniques have been used to analyze the performance; however, this is the first book to provide a unified approach to the performance evaluation problem by means of an approximate analytical technique called equilibrium point analysis. Two types of packet broadcast networks - satellite networks and local area networks are considered, and eight multiple access protocols are studied and their performance analyzed in terms of throughput and average message delay. Contents Part I: Fundamentals - Multiple Access Protocols and Performance - Equilibrium Point Analysis - Part II: Satellite Networks - S-ALOHA - R-ALOHA - ALOHA-Reservation - TDMAReservation - SRUC - TDMA - Performance Comparisons of the Protocols for Satellite Networks - Part III: Local Area Networks - Buffered CSMACD - BRAM Performance Analysis of Multiple Access Protocols is included in the Computer Systems Series, Research Reports and Notes, edited by Herb Schwetman.

This book was released on 2005 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Carrier Sense Multiple Access with Collision Detection (CSMA/CD), Ethernet Local Area Networks (LANs) suffers from capture effect in packet loss. As a result of capture effect, some nodes may be locked-out using the medium for a period of time. Hence, CSMA/CD based Enthernet is unsuitable for real-time multimedia traffic. It does not guarantee delay bound, behaves poorly under heavy load conditions. To overcome these shortcomings and enhance performace of CSMA/CD base LAN, three new concepts are added to the conventional CSMA/CD. Firstly, each node in the LAN has a finite buffer. A nodes competes for access to the medium after its buffer is full. It will transmit all packets in the buffer if access is permitted. To minimize the waiting delay of packets in the buffer prior to transmission, a time-out period is set, beyond which a node is tries to transmit considering its buffer is full. Due to buffer, the number of nodes trying to transmit at a time is reduced, thereby collision rates is reduced. Capture effect, locked-out probability, bandwidth loss, and backoff delays are also reduced. To support all types of traffic ( mainly real-time traffic), the optimum buffer size obtained is 10 packets/buffer. Using this buffer, multimedia traffic can be sent in a streamed fashion within a delay bound. Secondly, the maximum retransmission attempt limit and backoff limit are reduced to 10 and 8 times respectively to guarantee a tolerable delay for multimedia applications. A new special-jamming signal is introduced. It gives transmission priority to the node that already has finished its maximum retransmission attempt. This prevents packet loss and quality degradation of received normal data traffic and multimedia traffic. The final one is the priority scheduler, which is activated when multiple modes send the special-jamming signal at a time. It gives permission to the node having either the lowest time-stamp of the smallest source of address (SA) to transmit while other nodes wait until their access is permitted accordingly. The proposed protocol is based on bus topology for a single channel LAN. Throughput, transmission efficiency, average delay and percentage of collision of the proposed network is evaluated against number of nodes, bus length and offered load within two enviroments, i.e. Fast Ethernet and Gigabit Enthernet. The results show significant performance improvement. Throughput, transmission efficiency are increased more than 10% average. On the other hand, average delay and percentage of collision are reduced to less than 2 ms and 3.5% respectively compared to the conventional CSMA/CD based LAN.

Available in PDF, EPUB and Kindle. Book excerpt: The First International ICST Conference on Sensor Systems and Software (S-cube 2009) was held during 7–8 September in Pisa, Italy. This new international conference was dedicated to addressing the research challenges facing system dev- opment and software support for systems based on wireless sensor networks (WSNs) that have the potential to impact society in many ways. Currently, wireless sensor networks introduce innovative and interesting application scenarios that may support a large amount of different applications including environmental monitoring, disaster prevention, building automation, object tracking, nuclear reactor control, fire det- tion, agriculture, healthcare, and traffic monitoring. The widespread acceptance of these new services can be improved by the definition of frameworks and architectures that have the potential to radically simplify software development for wireless sensor network-based applications. The aim of these new architectures is to support flexible, scalable programming of applications based on adaptive middleware. As a con- quence, WSNs require novel programming paradigms and technologies. Moreover, the design of new complex systems, characterized by the interaction of different and heterogeneous resources, will allow the development of innovative applications that meet high-performance goals. Hence, WSNs require contributions from many fields such as embedded systems, distributed systems, data management, system security and applications. The conference places emphasis on layers well above the traditional MAC and routing and transport layer protocols.

This book was released on 2018-06-27 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the study of a simple but effective media access protocol for high data rate networks are presented. The protocol is based on the fact that at high data rates networks can contain multiple messages simultaneously over their span, and that in a ring, nodes used to detect the presence of a message arriving from the immediate upstream neighbor. When an incoming signal is detected, the node must either abort or truncate a message it is presently sending. Thus, the protocol with local carrier sensing and multiple access is designated CSMA/RN. The performance of CSMA/RN with TTattempt and truncate is studied using analytic and simulation models. Three performance factors, wait or access time, service time and response or end-to-end travel time are presented. The service time is basically a function of the network rate, it changes by a factor of 1 between no load and full load. Wait time, which is zero for no load, remains small for load factors up to 70 percent of full load. Response time, which adds travel time while on the network to wait and service time, is mainly a function of network length, especially for longer distance networks. Simulation results are shown for CSMA/RN where messages are removed at the destination. A wide range of local and metropolitan area network parameters including variations in message size, network length, and node count are studied. Finally, a scaling factor based upon the ratio of message to network length demonstrates that the results, and hence, the CSMA/RN protocol, are applicable to wide area networks. Foudriat, E.
