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 Distributed Dynamic Channel Access Scheduling for Ad Hoc Networks written by and published by . This book was released on 2002 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three types of collision-free channel access protocols for ad hoc networks are presented. These protocols are derived from a novel approach to contention resolution that allows contending entities to elect one or multiple winners for channel access in any given contention context (e.g., a time slot) in a distributed fashion. In multihop wireless networks, the only required information for each entity is the identifiers of its neighbors one and two hops away. The new protocols are shown to be fair and capable of achieving maximal utilization of the channel bandwidth. The delay and throughput characteristics of the contention resolution algorithms are analyzed, and the performance of the three types of channel access protocols is studied by simulations and compared with that of optimal static scheduling algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The past few years have experienced a steep growth in research in the area of wireless ad hoc networks. The attractiveness of ad hoc networks, in general, is attributed to their characteristics/features such as ability for infrastructure-less setup, minimal or no reliance on network planning and the ability of the nodes to self-organize and self-configure without the involvement of a centralized n- work manager, router, access point or a switch. These features help to set up a network fast in situations where there is no existing network setup or in times when setting up a fixed infrastructure network is considered infeasible, for example, in times of emergency or during relief operations. Even though ad hoc networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to scalability, quality-of-service, energy efficiency and security.
Book Synopsis Hybrid Channel Access Scheduling in Ad Hoc Networks by :
Download or read book Hybrid Channel Access Scheduling in Ad Hoc Networks written by and published by . This book was released on 2002 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the hybrid activation multiple access (HAMA) protocol for ad hoc networks. Unlike previous channel access scheduling protocols that activate either nodes or links only, HAMA is a node-activation channel access protocol that also maximizes the chance of link activations using time- and code-division schemes. HAMA only requires identifiers of the neighbors within two hops from each node to schedule channel access. Using this neighborhood information, each node determines whether to transmit in the current time slot on a dynamically assigned spreading code. A neighbor protocol supplements HAMA with up-to-date two-hop neighborhood information by reliably propagating the one-hop neighbor updates through a novel random access technique. The throughput and delay characteristics of HAMA in randomly-generated multihop wireless networks are studied by analyses and simulations. The results of the analyses show that HAMA achieves higher channel utilization in ad hoc networks than a distributed scheduling scheme based on node activation, similar throughout as a well-known scheduling algorithm based on complete topology information, and much higher throughout than the ideal CSMA and CSMA/CA protocols.

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.
