Multimedia Conferencing System
ISBN: 9783639238525 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. With the convergence of IP based multimedia and communications, multipoint multimedia conferencing is becoming an important form of communication. There are two major problems that have plagued multimedia conferencing. The first is a form of control needed over the conference to maintain order and data integrity. The second is to optimise the bandwidth requirement as network bandwidth generally increase proportionally to the number of participants within the conference. Both the above problems place a serious limitation on the number of conference participants. The control criteria proposed...

Visualizing Network Traffic
ISBN: 9783639251401 / Angielski / Miękka / 200 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Network packet traces, despite having a lot of noise, contain priceless information, especially for investigating security incidents and performance problems. However, given the gigabytes of ow crossing a typical enterprise network every day, spotting malicious activity and analyzing trends become tedious tasks. Therefore, the appropriate representation of traffic data to the human user is crucial to network security. In this book, we bring together two powerful tools from different areas of application: SiLK (System for Internet-Level Knowledge), for command-based network trace analysis; and...

Einige Netzwerkprotokolle, darunter auch das Domain Name System (DNS) Protokoll, sind in den meisten Netzwerken vom Intranet ins Internet gestattet. Dieser Umstand kann durch Tunneling ausgenutzt werden - im vorliegenden Fall durch die (RFC-konforme) missbrauchliche Verwendung eines Protokolls - um eine Firewall zu umgehen indem TCP Verkehr RFC konform im DNS Protokoll untergebracht wird. Hierzu wird ein DNS Server dahingehend manipuliert, DNS Anfragen an eine Subdomain an einen anderen Nameserver zu delegieren. An diesem Rechner beantwortet allerdings kein Nameserver sondern spezielle...

Wireless Networks
ISBN: 9783639172676 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this thesis we study the effect of interference and methods of coping with it in a wireless network. We approach the problem from three different perspectives. The rst which involves physical layer is a method to cancel out interference in a multi-access channel. We consider J transmitter units each equipped with N transmit antennas over wireless Rayleigh fading channels. Previously, it was proved that when each transmitter unit has N transmit antennas, using (J 1)N + r receive antennas for any r 1, the receiver can completely separate the signals of J users. The provided diversity to each...

Topology Control for Mobile Ad hoc Networks
ISBN: 9783639257038 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this book, we aim to design and implement algorithms in a distributed environment in order to solve clustering, backbone formation and efficient routing problems for mobile ad hoc networks(MANET)s. Our first goal is to find a connected dominating set (CDS), then construct clusters using the clusterhead information and extend this approach to multi-level clusters. We propose a new connected dominating set based clustering algorithm for clustering in MANETs. In our algorithm we propose a heuristic based approach by considering degrees of the nodes during node selection. We also extend our...

Optimizing Mac Performance in Multi-Hop Wireless Networks
ISBN: 9783639124545 / Angielski / Miękka / 204 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. As wireless communication technology becomes increasingly available, multi-hop wireless networks such as wireless sensor networks and mesh networks are receiving substantial attention. However, traditional contention-based wireless MAC protocols such as IEEE 802.11 DCF are designed for single-hop wireless networks and do not perform well in multi- hop scenarios due to inefficiency in their medium reservation mechanisms. In this thesis, a new general method is introduced to improve their efficiency in wireless medium reservation for multi- hop wireless networks. With the help of...
