Link reversal is a versatile algorithm design technique that has been used in numerous distributed algorithms for a variety of problems. The common thread in these algorithms is that the distributed system is viewed as a graph, with vertices representing the computing nodes and edges representing some other feature of the system (for instance, point-to-point communication channels or a conflict relationship). Each algorithm assigns a virtual direction to the edges of the graph, producing a directed version of the original graph. As the algorithm proceeds, the virtual directions of some of the links in the graph change in order to accomplish some algorithm-specific goal. The criterion for changing link directions is based on information that is local to a node (such as the node having no outgoing links) and thus this approach scales well, a feature that is desirable for distributed algorithms. This monograph presents, in a tutorial way, a representative sampling of the work on link-reversal-based distributed algorithms. The algorithms considered solve routing, leader election, mutual exclusion, distributed queueing, scheduling, and resource allocation. The algorithms can be roughly divided into two types, those that assume a more abstract graph model of the networks, and those that take into account more realistic details of the system. In particular, these more realistic details include the communication between nodes, which may be through asynchronous message passing, and possible changes in the graph, for instance, due to movement of the nodes. We have not attempted to provide a comprehensive survey of all the literature on these topics. Instead, we have focused in depth on a smaller number of fundamental papers, whose common thread is that link reversal provides a way for nodes in the system to observe their local neighborhoods, take only local actions, and yet cause global problems to be solved. We conjecture that future interesting uses of link reversal are yet to be discovered.

Properties Of Link Reversal Algorithms For Routing And Leader Election written by Tsvetomira Radeva and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2013 with categories.

We present two link-reversal algorithms and some interesting properties that they satisfy. First, we describe the Partial Reversal (PR) algorithm [13], which ensures that the underlying graph structure is destination-oriented and acyclic. These properties of PR make it useful in routing protocols and algorithms for solving leader election and mutual exclusion. While proofs exist to establish the acyclicity property of PR, they rely on assigning labels to either the nodes or the edges in the graph. In this work we present simpler direct proof of the acyclicity property of partial reversal without using any external or dynamic labeling mechanisms. Second, we describe the leader election (LE) algorithm of [16], which guarantees that a unique leader is elected in an asynchronous network with a dynamically-changing communication topology. The algorithm ensures that, no matter what pattern of topology changes occurs, if topology changes cease, then eventually every connected component contains a unique leader and all nodes have directed paths to that leader. Our contribution includes a complexity analysis of the algorithm showing that after topology changes stop, no more than 0(n) elections occur in the system. We also provide a discussion on certain situations in which a new leader is elected (unnecessarily) when there is already another leader in the same connected component. Finally, we show how the LE algorithm can be augmented in such a way that nodes also have the shortest path to the leader.

"Ad hoc networking" enables wireless devices to network with each other as needed, even when access to the Internet is unavailable. It enables a wide range of powerful applications, from instant conferencing between notebook PC users to emergency and military services that must perform in the harshest conditions. In this book, the field's leading researchers present today's newest, most sophisticated techniques for making network applications available anytime, anywhere. They present state-of-the-art design and implementation techniques designed to instantly network a wide variety of mobile, wireless devices without access to routers, base stations, or Internet Service Providers. Learn how ad hoc networks utilize existing IP addresses, but require new protocol engineering. Understand cluster-based networks, Dynamic Source Routing (DSR) protocols, Ad Hoc Routing Protocols, reconfigurable wireless and other approaches. Finally, review each leading application for ad hoc networking, including mobile conferencing, home networking, emergency/disaster services, Personal Area Networks (PANs), Bluetooth integration; and embedded, military, and automotive applications.
