The capacity of ad-hoc wireless networks is constrained by the mutual interference of concurrent transmissions between nodes. We study a model of an ad-hoc network where n nodes communicate in random source-destination pairs. These nodes are assumed to be mobile. We examine the per

Abstract. Traditional software development tools such as CVS and Subversion do not inform users about concurrent modifications while they work on shared projects in their local workspaces. We propose an awareness mechanism that informs users about location of concurrent changes at the level

attain high levels of concurrency, while respecting application-specific delivery ordering constraints, and have varying cost and performance that depend on the degree of ordering desired. In particular, a protocol that enforces causal delivery orderings is introduced and shown to be a valuable

changes to the basic structure of objects in the heap. However, these implementations perform poorly because they interpose on all accesses to shared memory in the atomic block, redirecting updates to a thread-private log which must be searched by reads in the block and later reconciled with the heap when

. This can lead to conflicting or redundant changes. We propose an awareness mechanism that informs users about the concurrent published changes by annotating the local project with these modifications. Users can continue working without integrating the concurrent changes being notified about the location

Suppose you and I are both editing a document. You make and change and I make a change, concurrently. Now if we want to still be seeing the same document then I need to apply your change after mine and you mine after yours. But we can’t just apply them willy-nilly. I must amend yours somehow

, in a Wall Street Journal article, claimed that “when it comes to technology, even the most bearish analysts agree the microchip and Internet are changing almost everything in the economy” (Ip, 2000). Or as an article in Fortune (June 8, 1998, pp. 86–87) magazine put it, “The [computer] chip has

broadcasts to the group as an entity, group membership changes, and even migration of an activity from one place to another appear to occur instantaneously -- in other words, synchronously. A major advantage to this approach is that many aspects of a distributed application can be treated independently

of movements that change the rat's location in an environment. During movement through the place field, the complex spike cells often fire in a bursting pattern with an interburst frequency in the same range as the concurrent electroencephalograph theta. The present study examined the phase of the theta

The main problems associated with debugging concurrent programs are increased complexity, the “probe effect, ” nonrepeatability, and the lack of a synchronized global clock. The probe effect refers to the fact that any attempt to observe the behavior of a distributed system may change the behavior
