XTC: A Practical Topology Control Algorithm for Ad-Hoc Networks
Abstract: The XTC AD-HOC network topology control algorithm introduced shows three main advantages over previously proposed algorithms. First, it is extremely simple and strictly local. Second, it does not assume the network graph to be a unit disk graph; XTC proves correct also on general weighted network graphs. Third, the algorithm does not require availability of node position information. Instead, XTC operates with a general notion of order over the neighbors' page link quali ....etc

Real-time video transmission over ad hoc networks faces many challenges in cluding low bandwidth, long end-to-end delay, high packet loss rate, frequently changing topology and limited-powered mobile nodes. This paper presents an effective real-time video transmission scheme and improves implementation of DSR (Dynamic Source Routing) protocol. set up a test-bed by using DSR routing in the IP layer, and an application transmitting video stream over UDP protocol. We get a continuous JPEG image stream from a ZC0301p web camera and split each image ....etc

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

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

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

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 near-optimal multi cast scheme for mobile ad hoc networks using a hybrid genetic algorithm
Abstract: Multi cast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack of redundancy, multiple paths and multicast tree structure. Tree graph optimization problems (GO ....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
