EFFICIENT MULTICAST ALGORITHMS FOR MULTI-RADIO WIRELESS AD HOC NETWORKS
INTRODUCTION
WIRELESS AD HOC NETWORKS
Wireless ad hoc networks consist of mobile nodes connecting over a shared wireless channel. A wireless ad hoc network is a decentralized wireless network. The network is ad hoc because it does not rely on a preexisting infrastructure.
MULTICAST
Multicast provide efficient data distribution among a group of nodes. In wireless ad hoc networks, multicast algorithms are designed to be energy effi ....etc

Abstract
This paper investigates how to support multicasting in wireless ad hoc networks without throttling the dominant unicast flows. Unicast flows are usually congestion-controlled with protocols like TCP. However, there are no such protocols for multicast flows in wireless ad hoc network ....etc

ABSTRACT

Security is a major concern in the design of modern communication systems. It is articularly challenging with wireless networks such as Ad hoc networks. Ad hoc networks are dynamically reconfigured. For this reason they are vulnerable to several major sec ....etc

Abstract
Wireless ad hoc networks (also referred to as packet radio networks and multi-hop radio networks) consist of mobile nodes communicating over a shared wireless channel. Contrary to cellular networks, where the nodes are restricted to communicate with a set of carefully placed base stations, in wireless ad hoc networks there are no base stations; any two nodes are allowed to communicate directly if they are close enough, and nodes must use multi-hop routing to deliver their packets to distant destinations. The ....etc

Abstract
A mobile ad hoc network is a mobile, multihop wireless network that does not rely on any preexisting infrastructure. Mobile ad hoc networks are characterized by dynamic topologies due to uncontrolled node mobility, limited and variable shared wireless channel bandwidth, and wireless devices constrained by battery power. One of the key challenges in such networks is to design dynamic routing protocols that are efficient, i.e., consume less overhead. The key characteristic of an on-demand protocol is the source-initia ....etc

Abstract

In this paper, we propose an Identity (ID)-based Secure Routing Scheme for secure routing in wireless ad-hoc networks. It make use of Identity based Signature scheme and hash chains to secure the AODV (Ad-hoc on demand distance vector routing) messages. We have used ID based Signature scheme for the immutable fields, that is the fields that remain same throughout the journey of the routing packet and Hash Chains for the mutable fields (fields which changes from node to node) e.g. Hop Count. This system has the following adva ....etc

Novel Defense Mechanism Against Data Flooding Attacks In Wireless Ad Hoc Networks

– Consumer Electronics – Java

Mobile users like to use their own consumer electronic devices anywhere and at anytime to access multimedia data. Hence, we expect that wireless ad hoc networks will be widely used in the near future since these networks form the topology with low cost on the fly. However, consumer electronic devices generally operate on limited battery power and therefore are vulnerable to security threats like data flooding attacks. ....etc

ABSTRACT
Opportunistic routing has recently attracted much attention as it is considered a promising direction for improving the performance of wireless ad hoc and sensor networks. With opportunistic routing, intermediate nodes collaborate on packet forwarding in a localized and consistent manner. Opportunistic routing greatly increases transmission reliability and network throughput by taking advantage of the broadcast nature of the wireless medium. In this article we first illustrate the basic idea behind opportunistic routing, and then cate ....etc
