Abstract—Wireless Mesh Network (WMN) has become an important edge network to provide Internet access to remote areas and wireless connections in a metropolitan scale. In this paper, we study the problem of identifying the maximum available bandwidth path, a fundamental issue in supporting quality-of-service in WMNs. Due to interference among links, bandwidth, a well-known bottleneck metric in wired networks, is neither concave nor additive in wireless networks. We propose a new path weight which captures the available path bandwidth informati ....etc

Selective Encryption of Still Image
Abstract: In some applications, it is relevant to hide the content of a message when it enters an insecure channel. The accepted view among professional cryptographers is that the encryption algorithm should be published, whereas the key must be kept secret. In the field of image cryptography, the focus has been put on steganography and in particular on watermarking during the last years. Watermarking, as opposed to steganography has the additional requirement of robustness against possible image transform ....etc

ABSTRACT

An ad hoc wireless network is an autonomous self-organizing system of mobile nodes connected by wireless links where nodes not in direct range can communicate via intermediate nodes. A common technique used in routing protocols for ad hoc wire ....etc

Abstract—
Multihop wireless networks rely on node cooperation to provide multicast services. The multihop communication offers increased coverage for such services but also makes them more vulnerable to insider (or Byzantine) attacks coming from compromised nodes that behave arbitrarily to disrupt the network. In this work, we identify vulnerabilities of on-demand multicast routing protocols for multihop wireless networks and ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Seminar on Byzantine-ResilientSecure Multicast Routing in Multi-hop Wireless Networks


INTRODUCTION

Multicast routing protocols deliver data from a source to multiple destinations organized in a multicast
group. Several protocols were proposed to provide multicast services for multi-hop wireless networks.
These protocols rely on node cooperation and use flooding , gossip , geographical position , or
dissemination structures such as meshes , , or trees , .

Incremental deployment service of Hop by hop multicast routing protocol
Abstract: IP multicast is facing a slow take-off although it has been a hotly debated topic for more than a decade. Many reasons are responsible for this status. Hence, the Internet is likely to be organized with both unicast and multicast enabled networks. Thus, it is of utmost importance to design protocols that allow the progressive deployment of the multicast service by supporting unicast clouds. This paper presents HBH (hop-by-hop multicast routing protocol). HBH adop ....etc
