Download or read book Discrete Event Dynamic System Based Approaches for Scheduling Transmissions in Multihop Packet Radio Networks written by and published by . This book was released on 1993 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the classic transmission scheduling problem, the nodes of a Packed Radio Network (PRN) broadcast fixed-length packets over a common resource (the channel). Packet transmissions are subject to interference constraints; for example, if a node is transmitting a packet, then all adjacent (neighboring) nodes must refrain from transmission. One then adopts a slotted time model where every slot is allocated to a set of nodes which can simultaneously transmit without conflict. Thus, a node is generally belongs to one or more of these sets(called transmission sets). Our approach is based on viewing the transmission scheduling problem as a single server multiclass polling problem with simultaneous resource possession. Here, a class corresponds to a transmission set. The server corresponds to a channel operating with deterministic service times: a service time is equal to one time slot required for transmitting a packet. The scheduling problem is then equivalent to assigning the server (equivalently, each time slot) to a particular transmissions set. The simultaneous resource possession feature arises because the server is assigned to a transmission set, i.e. it can simultaneously provide service to packets from all nodes which belong to that set. The construction of the transmission set is dependent upon the topology and connectivity of the PRN and is equivalent to a graph partitioning problem. For our purposes, we assume M transmission sets have been specified. Finally, we allow for overlapping transmission sets, i.e. a node can belong to two or more difference transmission sets.

Abstract: Abstract of thesis entitled "Distributed Scheduling in Multihop Ad Hoc Networks" Submitted by Sun Yijiang for the degree of Master of Philosophy at The University of Hong Kong in February 2008 A multihop ad hoc network is a network formed by multiple nodes with- out the aid of any centralized administration, and data traffic is typically forwarded by multiple intermediate nodes before reaching its destination. In this thesis, we focus on improving QoS of end-to-end traffic flows in multihop ad hoc networks through packet transmission scheduling. Our approach was to design a framework in which existing schedul- ingalgorithmsoriginallydesigned forinfrastructure-basedwirelessnetworks could be adapted to multihop ad hoc networks. While infrastructure-based wireless scheduling has been studied extensively and most of the proposed algorithms handle the characteristics of wireless medium in an effective and fairway, ourapproach aimstogeneralizetheadaptationofthese algorithms to ad hoc networks and thus to make maximum use of the existing resource of wireless scheduling. iThe framework consists of two sets of mechanisms. The first one is an end-to-end service compensation mechanism. Each multihop flow is asso- ciated with some QoS requirement, which is requested and granted in the form of the desired service rate. The achieved rate is estimated at the des- tination and fed back to the source periodically. Both the desired rate and achieved rate of a multihop flow are propagated from the source node to all its downstream relaying nodes. With this information, a compensation- capable scheduling algorithm originally designed for infrastructure-based wireless networks can be adapted to each ad hoc node for error compensa- tion. The second part of the framework is a set of mechanisms for distributed opportunistic scheduling in multihop wireless ad hoc networks. The frame- work includes a wireless link state estimation mechanism, a requirement on medium access control protocol and two mechanisms to limit the access of the wireless medium. The link state estimation mechanism provides the necessary status of each wireless link and thus enables the adaptation of various opportunistic scheduling algorithms. The performance ofthe proposed framework was evaluated by computer simulations.

Download or read book Routing Flow and Capacity Design in Communication and Computer Networks written by Michal Pioro and published by Elsevier. This book was released on 2004-07-21 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: In network design, the gap between theory and practice is woefully broad. This book narrows it, comprehensively and critically examining current network design models and methods. You will learn where mathematical modeling and algorithmic optimization have been under-utilized. At the opposite extreme, you will learn where they tend to fail to contribute to the twin goals of network efficiency and cost-savings. Most of all, you will learn precisely how to tailor theoretical models to make them as useful as possible in practice.Throughout, the authors focus on the traffic demands encountered in the real world of network design. Their generic approach, however, allows problem formulations and solutions to be applied across the board to virtually any type of backbone communication or computer network. For beginners, this book is an excellent introduction. For seasoned professionals, it provides immediate solutions and a strong foundation for further advances in the use of mathematical modeling for network design. Written by leading researchers with a combined 40 years of industrial and academic network design experience.

Download or read book Real time Communication Protocols for Multi hop Ad hoc Networks written by Reinhard Gotzhein and published by Springer Nature. This book was released on 2020-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on core functionalities for wireless real-time multi-hop networking with TDMA (time-division multiple access) and their integration into a flexible, versatile, fully operational, self-contained communication system. The use of wireless real-time communication technologies for the flexible networking of sensors, actuators, and controllers is a crucial building block for future production and control systems. WirelessHART and ISA 100.11a, two technologies that have been developed predominantly for industrial use, are currently available. However, a closer analysis of these approaches reveals certain deficits. Current research on wireless real-time communication systems shows potential to remove these limitations, resulting in flexible, versatile, and robust solutions that can be implemented on today’s low-cost and resource-constrained hardware platforms. Unlike other books on wireless communication, this book presents protocols located on MAC layer and above, and build on the physical (PHY) layer of standard wireless communication technologies.

Available in PDF, EPUB and Kindle. Book excerpt: This book surveys state-of-the-art optimization modeling for design, analysis, and management of wireless networks, such as cellular and wireless local area networks (LANs), and the services they deliver. The past two decades have seen a tremendous growth in the deployment and use of wireless networks. The current-generation wireless systems can provide mobile users with high-speed data services at rates substantially higher than those of the previous generation. As a result, the demand for mobile information services with high reliability, fast response times, and ubiquitous connectivity continues to increase rapidly. The optimization of system performance has become critically important both in terms of practical utility and commercial viability, and presents a rich area for research. In the editors' previous work on traditional wired networks, we have observed that designing low cost, survivable telecommunication networks involves extremely complicated processes. Commercial products available to help with this task typically have been based on simulation and/or proprietary heuristics. As demonstrated in this book, however, mathematical programming deserves a prominent place in the designer's toolkit. Convenient modeling languages and powerful optimization solvers have greatly facilitated the implementation of mathematical programming theory into the practice of commercial network design. These points are equally relevant and applicable in today’s world of wireless network technology and design. But there are new issues as well: many wireless network design decisions, such as routing and facility/element location, must be dealt with in innovative ways that are unique and distinct from wired (fiber optic) networks. The book specifically treats the recent research and the use of modeling languages and network optimization techniques that are playing particularly important and distinctive roles in the wireless domain.

Download or read book Age of Information written by Yin Sun and published by Springer Nature. This book was released on 2022-06-01 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information usually has the highest value when it is fresh. For example, real-time knowledge about the location, orientation, and speed of motor vehicles is imperative in autonomous driving, and the access to timely information about stock prices and interest rate movements is essential for developing trading strategies on the stock market. The Age of Information (AoI) concept, together with its recent extensions, provides a means of quantifying the freshness of information and an opportunity to improve the performance of real-time systems and networks. Recent research advances on AoI suggest that many well-known design principles of traditional data networks (for, e.g., providing high throughput and low delay) need to be re-examined for enhancing information freshness in rapidly emerging real-time applications. This book provides a suite of analytical tools and insightful results on the generation of information-update packets at the source nodes and the design of network protocols forwarding the packets to their destinations. The book also points out interesting connections between AoI concept and information theory, signal processing, and control theory, which are worthy of future investigation.
