Co-operative cache based data access in ad hoc networks

Wireless ad hoc network is a collection of autonomous nodes or terminals that communicate with each other by forming a multihop radio network and maintaining connectivity in a decentralized manner. Since the nodes communicate over wireless links, they have to contend with the effects of radio communication, such as noise, fading, and interference. In addition, the links typically have less bandwidth than in a wired network. Each node in a wireless ad hoc network functions as both a host ....etc

Mobile ad-hoc networks (MANETs) are becoming more popular due to their ability to model interesting aspects of real wireless networks. It is easy and cheap to build such networks because no other equipment or infrastructure are required besides the mobile devices. An MANET is composed of a set of nodes distributed in the plane. A signal sent by any node can be received by all the nodes within its transmission range, which is usually taken as one unit distance. One of the primary issues related to MANETs is the development of efficient routing a ....etc

Toward Broadcast Reliability in Mobile Ad Hoc Networks with Double Coverage. (A New TCP for Persistent Packet Reordering).

Abstract:

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorith ....etc

A mobile ad hoc network (MANET) is a type of wireless ad hoc network, and is a self-configuring network of mobile devices connected by any number of wireless links. Every device in a MANET is also a router because it is required to forward traffic unrelated to its own use. Each MANET device is free to move independently, in any arbitrary direction, and thus each device will potentially change its links to other devices on a regular basis. The primary challenge for building a MANET is for each device to continuously maintain the information req ....etc

Ad-Hoc Networks Seminar

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. Th ....etc

Content Based Multicast Model In Ad Hoc Network

Abstract :

In this model, the content of the multicast data determines the receiver set for the data and the receiver set changes dynamically as the content of the multicast changes. Delivering the multicast to intended receivers while minimizing the message overhead and reducing battery consumption is a challenge made harder because of node mobility. This novel multicast model that distributes this form of threat information in a message efficient manner. In this report, result from detai ....etc

A Novel Secure Communication Protocol for Ad Hoc networks
Abstract: An ad hoc network is a self organized entity with a number of mobile nodes without any centralized access point and also there is a topology control problem which leads to high power consumption and no security, while routing the packets between mobile hosts. Authentication is one of the important security requirements of a communication network. The common authentication schemes are not applicable in Ad hoc networks. In this paper, we propose a secure communication prot ....etc

Summary: A mobile ad hoc network (MANET) is a collection of mobile nodes that forms a provisional network dynamically without the aid of any predetermined infrastructure. The salient nature of ad hoc networks renders them vulnerable to numerous types of security attacks. The dynamic feature of ad hoc networks makes enforcement of security become an extremely challenging issue. The main problem of many proposed routing protocols for ad hoc networks is that these protocols have critical susceptibilities to security attacks. Effective operation of ....etc

Bluetooth Ad Hoc Networking

Abstract :

Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices. The problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. In this Seminar we have introduce two novel protocols for forming connected scatternets. In both cases, the resulting topology is termed a bluetree. We also address the problem of determining an opt ....etc

Mobile Ad Hoc Networks (MANETs) are networks in which all nodes are mobile and communicate with each other via wireless connections. Nodes can join or leave at anytime. There is no fixed infrastructure, all nodes are equal and there is no centralized control or overview. There are no designated routers: all nodes can serve as routers for each other, and data packets are forwarded from node to node in a multi-hop fashion.

Since a few years research interest in MANETs has been growing, and especially the design of MANET routing protocols has r ....etc
