An ad hoc wireless network is composed of mobile hosts without any wired infrastructure support. In mobile ad hoc networks, unicast and multicast routing protocols are faced with the challenge of producing multihop routes because of limited radio propagation range. In addition, routing protocols must manage mobility and be bandwidth and power efficient. The On-Demand Multicast Routing Protocol ...

MAND (Mobile Ad Hoc Network Directory) is a middleware infrastructure for the distribution, storage, and lookup of key/value pairs in ad hoc networks. The key insight in MAND is to piggyback tuples and requests on the messages that routing protocols exchange to build and maintain routes in the ad hoc network. MAND can be used with different routing protocols and does not require any modificatio...

Ad hoc wireless networks consist of mobile nodes interconnected by multihop communication paths. Unlike conventional wireless networks, ad hoc networks have no fixed network infrastructure or administrative support. The topology of the network changes dynamically as mobile nodes join or depart the network or radio links between nodes become unusable. This article addresses some of the quality o...

Abstracr-In this paper we investigate the performance of multicast routing protocols in wireless mobile ad hoc networks. An ad hoc network is composed of mobile nodes without the presence of a wired support infrastructure. In this environment, routinghulticasting protocols are faced with the challenge of producing multihop routes under host mobility and bandwidth constraints. In recent years, a...

“Anywhere” and, in particular, “anyhow”: these are the two best words that can describe an ad hoc wireless network that is due to the increasing demand for connectivity in such an information society. Ad hoc wireless networks can be described as dynamic multihop wireless networks with mobile nodes. However, the mobility condition can be relaxed, and we can consider an ad hoc wireless network as...

In this paper, we are converting AODV (Adhoc On-demand Distance Vector) protocol in to an efficient routing algorithm called EORP (Efficient on-demand routing protocol) for mobile ad-hoc networks with a route establishment technique using Bayesian approach. A mobile ad-hoc network (MANET) is a self-configuring infrastructure less network of mobile devices connected by multihop-communication pat...

In vehicular ad hoc networks (VANETs), the medium access control (MAC) protocol is of great importance to provide time-critical safety applications. Contemporary multihop broadcast protocols in VANETs usually choose the farthest node in broadcast range as the forwarder to reduce the number of forwarding hops. However, in this paper, we demonstrate that the farthest forwarder may experience larg...

Multicast-based data communication is an efficient communication scheme especially in multihop ad hoc networks where the MAC layer is based on one-hop broadcast from one source to multiple receivers. The problem of resource allocation for a set of homogeneous multicast sessions over multihop wireless network is addressed. An iterative algorithm is proposed that achieves the optimal rates for a ...

Abstract— The topology of wireless multihop ad hoc networks can be controlled by varying the transmission power of each node. We propose a simple distributed algorithm where each node makes local decisions about its transmission power and these local decisions collectively guarantee global connectivity. Specifically, based on the directional information, a node grows it transmission power until...
