Most currently proposed solutions to application-level multicast organize the group members into an application-level mesh over which a Distance-Vector routing protocol, or a similar algorithm, is used to construct source-rooted distribution trees. The use of a global routing protocol limits the scalability of these systems. Other proposed solutions that scale to larger numbers of receivers do ...

We present LFR (Loop Free Routing), a new loop-free distance vector routing algorithm, which is able to update the shortest paths of a distributed network with n nodes in fully dynamic scenarios. If Φ is the total number of nodes affected by a set of updates to the network, and φ is the maximum number of destinations for which a node is affected, then LFR requires O(Φ ·∆) messages and O(n+φ ·∆)...

Abstract. We investigate the form of the Coulomb potential of a point charge in a noncommutative geometry, using a state of minimal dispersion. We find the deviation of the potential at large distances from the point, distinguishing between coordinate distance and measured distance. Defining the “effective” value of an operator as its expectation value in a minimum dispersion state centered at ...

Spoken information retrieval is a promising domain of research. In this paper we describe our participation in the pilot Document Similarity Amid Automatically Detected Terms task of FIRE 2014. We present the findings on our experiments with variants of distance and timestamp based approaches. The de-normalized distance based variant outperformed other two delivering best results of the submitt...

The image identification problem consists in identifying all the equivalent forms of a given reference image. An image is equivalent to the reference image, if the former results from the application of an image operator (or a composition of image operators) to the latter. Depending on the application, different sets of image operators are considered. The equivalence quantification is done in t...

The need to have Intelligent Vehicle System has paved the way for the rapid emergence of Vehicular Adhoc Networks (VANET) which allows communication to take place between the vehicles. The effective implementation of VANET, a sub class of mobile adhoc networks, depends upon the routing protocols used which behave differently under different environments. This paper attempts to study the behavio...

Distance vector routing protocols (e.g., RIP) have been widely used on the Internet, and are being adapted to emerging wireless ad hoc networks. However, it is well-known that existing distance vector routing protocols are insecure due to: 1) the lack of strong authentication and authorization mechanisms; 2) the difficulty, if not impossibility, of validating routing updates which are aggregate...

A mobile ad-hoc network (MANET) is a wireless network where nodes can communicate with each other without infrastructure. Due to this nature of MANET, some malicious and selfish nodes that try compromise the routing protocol functionality and makes MANET vulnerable to Denial of Service attack in military communication environments. This paper considers military scenarios and evaluates the perfo...

We present a new multi-path routing methodology, MLBrouting, that is based on the multinomial logit model, which is well known in the random utility field. The key concept of the study is to set multiple paths from the origin to the destination, and distribute packets in accordance with multinomial logit type probability. Since MLB-routing is pure multi-path routing, it reduces the convergence ...

Mobile Ad hoc Networks (MANET’s) have become increasingly popular in infrastructure-less mobile wireless communication system. Nodes of these kinds of networks function as a router which discovers and maintains the route to the other nodes in the networks. Route discovery and packet forwarding operations need an efficient routing protocol. Ad-Hoc on Demand Distance Vector Routing Protocol (AODV...
