Available in PDF, EPUB and Kindle. Book excerpt: "Local Area Network (LAN) technology and the processing power of many of the components that make up the network are continuously changing. This includes the transmission medium, workstations, network elements (hubs, switches, bridges, routers, etc.), application software and protocols. Usually, network growth (evolution) and maintenance are performed in an ad-hoc manner; adding a workstation here and there, and hoping there is no network degradation or hoping that changes being made to the network will fix whatever ails it. Having a good understanding of how the network currently functions and establishing guidelines for adding components to the network should prevent network degradation. As is the case with many designs and products, predicting the behavior of a system (architecture) before it is deployed is desirable because it reduces the probability of problems seen by the customer. This philosophy applies to LAN architectures too. Modeling and simulation of a network architecture before it is deployed or changed can save an organization time and money. Modeling and simulation will provide an understanding of network functionality and allows for establishing guidelines for when, how, and where changes to a network should be applied."--Author's Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: A fast-growing area in the communications industry is the internetworking of an ever-increasing proliferation of computers, particularly via local area networks (LANs). The LAN is a resource-sharing data communications network being used by many offices to interchange information such as electronic mail, word processing, and files among computers and other devices. This unique book shows the user how to establish the performance characteristics of a LAN before putting it to use in a particular type of situation. Simulation of Local Area Networks consists of eight chapters, each with its own extensive list of references. The first chapter provides a brief review of local area networks, and the second chapter gives the analytical models of popular LANs-token-passing bus and ring networks, CSMA/CD LANs, and star networks. Chapter 3 covers general principles of simulation, and Chapter 4 discusses fundamental concepts in probability and statistics relating to simulation modeling. Materials in Chapters 3 and 4 are specifically applied in developing simulation models on token-passing LANs, CSMA/CD LANs, and star LANs in Chapters 5 through 7. The computer code in Chapters 5, 6, and 7 is divided into segments, and a detailed explanation of each segment is provided. The last chapter reviews special-purpose languages such as GPSS, SIMSCRIPT, GASP, SIMULA, SLAM, and RESQ. Helpful criteria for language selection are included. The entire code is put together in the appendixes. This book has two major advantages over existing texts. First, it uses C, a well-developed general-purpose language that is familiar to most analysts. Second, the text specifically applies the simulation principles to local area networks. No other book available shows the systems analyst how to evaluate the performance of existing or proposed systems under different kinds of conditions.

Download or read book Wireless Local Area Networks written by Efstathios D. Kyriakidis and published by . This book was released on 1998 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication is currently in a state of rapid evolution. This evolution is driven by the numerous advantages of the wireless networks. One major constraint to this evolution is the lack of standardization. Also a major concern are the interference problems of the signal at the reception point caused by the multiple paths that the electromagnetic waves travel (multi-path interference). This thesis presents two separate simulations. In the first, a realistic physical model of a wireless local area network is developed. In this simulation, the multi-path interference at the reception point is investigated. The results of this physics- based simulation are used to assess an important assumption in the second simulation. In the second simulation, we examine the reliability of the wireless standard for the medium access control (MAC) layer, using CACI COMNET ffi network simulation software. This standard was published in 1997, by the IEEE's working group 802.11 and in this thesis is tested and analyzed under different network loads. One major result is that the optimum load for a five working stations wireless LAN, is from 80 to 200 packets per second. Below that load range the channel utilization is small and above that the network is overloaded.

This book was released on 1998-12-01 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research to improve the performance of the IEEE 802.11 has been ongoing since 1990. The focus of this research has investigated the use of the MAC and Physical layers for improving throughput. An adaptive MAC protocol, CATER (Code Adapts To Enhance Reliability) is based on the proposed MAC standard for wireless local area networks (WLAN)-802. 11. IEEE 802.11 uses a fixed Pseudo-Noise (PN) code for spreading the information signal, implying a fixed process gain at the receiver. When the channel degrades, IEEE 802.11 offers only retransmissions at the MAC layer to contend with the corrupted medium. However, CATER allows communicating stations to reconfigure their transceivers to use a longer PN code after a prescribed number of failed retransmissions. The longer PN code increases the process gain of the receiver and reduces the error rate. This thesis analyzes the performance of CATER as changing the factor: Start (the number of transmission before the channel is reconfigured) and Max (additional frame transmissions during reconfigure), PN code length, the number of station, and implementing Forward Error Correction (FEC). CATER provides better throughput for smaller Start and larger Max at a high bit error rate (10-3). When CATER uses a PN code length of 63, the throughput is increased by 101 percent at high bit error rate (BER). However, 802.11 is better than CATER at low BER ( 10-3).

Available in PDF, EPUB and Kindle. Book excerpt: The progress being made in the disciplines of computer networks and simulation is clearly visible in networking projects. In addition to providing a state of the art review, this volume pays special attention to two important phenomena in this field: the direct translation from (protocol) specifications to simulation models, and the increasing role of distributed systems. In the first part of the book a perspective is given on the next stage in computer network development - the evolution of ISDN systems. The complexity of these systems, the interconnection of LANs, the current possibilities of modelling and simulation, and the role of artificial intelligence therein are all discussed. The second section concentrates on protocols, tools, and the difficulty of full and exhaustive testing. Areas addressed include: integration of specification and simulation; performance evaluation; simulation of gateway computers with modelling tools in the network cycle; analysis of the use of two integrated software environments, from specification to implementation; and a multisolver queueing system.

Available in PDF, EPUB and Kindle. Book excerpt: Local Area Networks (LANs) play a larger role in our lives today than ever before. For example, LANs provide us with the capability to realize automated banking services, with instant credit checking and numerous other diverse access and manipulation services. Users and developers of LAN products must understand the architecture of the hardware and software mechanisms to effectively design and use such systems. Most gains in LAN productivity will come from future software developments in systems management and applications. This book provides an introduction to the technology associated with Local Area Networks, emphasizing software aspects which have been secondary considerations to hardware in most existing texts. The book also provides a review of the technology needed to realize full service software products, such as computer-aided design and manufacturing systems, large publication systems, and integrated data service networks, and includes an exhaustive review of the products available today.

Available in PDF, EPUB and Kindle. Book excerpt: There are many exciting trends and developments in the communications industry, several of which are related to advances in fast packet switching, multi media services, asynchronous transfer mode (ATM) and high-speed protocols. It seems fair to say that the face of networking has been rapidly changing and the distinction between LANs, MANs, and WANs is becoming more and more blurred. It is commonly believed in the industry that ATM represents the next generation in networking. The adoption of ATM standards by the research and development community as a unifying technology for communications that scales from local to wide area has been met with great enthusiasm from the business community and end users. Reflecting these trends, the technical program of the First International Conference on LAN Interconnection consists of papers addressing a wide range of technical challenges and state of the art reviews. We are fortunate to have assembled a strong program committee, expert speakers, and panelists. We would like to thank Professor Schwartz for his keynote speech. We would like to thank Professor Yannis Viniotis and his students for the preparation of the index.

This book was released on 2010 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Seastar" is an underwater Local Area Network (LAN) concept involving high-frequency acoustic modems sending large volumes of data from a distributed set of peripheral sensor nodes to a centralized node for data fusion. The notional operating range of the acoustic modems used is 500m. This research considers four candidate Seastar network protocols: Time division multiple access (TDMA) polling with and without Selective automatic repeat request (SRQ), and TDMA token ring with and without SRQ. The number of peripheral nodes, the layout of the nodes, and the noise level of the environment are modeled and evaluated, according to performance metrics, including data throughput, communications latency, and packet error rate. It was determined that in a low-noise environment, the token ring with SRQ protocol delivers the most throughput of data with the minimum number of dropped packets, while in high-noise conditions, polling with SRQ is preferred. In addition, if data throughput is not a priority, polling with SRQ is advantageous. Therefore, it is recommended that a switch be implemented for adaptively selecting the network protocol depending on the prevailing noise conditions and the critical performance metrics.
