standard 802.11g, emphasizing the important safety protocols: WEP (Wired equivalent Privacy) and WPA (Wi-Fi Protected Access). Know-that today there are attacks from heavy users in the computer networks, in various ways and with several devices. Therefore becomes priority its network ensured that do not occure these attacks, which has as objective take information or secret archives. In the networks cordless that is not different. We’ll discuss how to make its wireless network more…

temos várias possíveis topologias: § Redes Estruturadas com Access Points (APs, possivelmente vários deles) provendo acesso a redes convencionais ou atuando como repetidores/roteadores entre si. BSS (Basic Service Set) para um Access Point ou ESS (Extended Service Set) para mais de um access point. 3 A Evolução dos Mecanismos de Segurança para Redes sem fio 802.11 Introdução à Computação Móvel § PUC-Rio Redes “Ad-Hoc” ou “Peer-to-peer”, sem APs, com topologia variável…

Segurança A segurança em 4 módulos eles são: Segurança modo 1 Autenticação e encriptação são ignoradas (Bypassed) Apenas suportando na versão 2 e anteriores. Segurança modulo 2 Medidas de segurança iniciadas após estabelecer o link Manager Protocol (LMP), mas antes de estabelecer o canal L2CAP. Suportando em todas as versões de Bluetooth. Segurança modulo 3 Medidas de seguranças iniciadas antes do link completamente estabelecido. Suportando a partir da versão 2…

com, alessandrobaba@bol.com.br, othon@pdntelecom.com.br Abstract. This article aims to define the scope of Software Defined Networks by such technological breakthrough arguing its benefits to the global network of computers and devices and thus to society, comparing it to the state of current networks. The OpenFlow protocol technology as a solution that can be implemented gradually in a production network, the point of failure that can occur with the insertion of new switches in a ready…

students of the Mechatornics Department. The project proposal is given by Dr. Nathir Rawashdeh from the teaching committee of the Mechatronics Department at German Jordanian University. The report is written as a research paper that can provide information to further development on the subject of modelling and controlling hexapod robots. Throughout the project, Excel has been used for data processing, simulating and presenting results. Also using 3D Max for designing the robot and…

can a switch create VLANs, ignore VTP messages, and not pass local VLAN information to other VTP domain members? • client • server • pruning • transparent 2. What are two characteristics of an extended ACL? (Choose two.) • IP is used to specify TCP traffic only. • IP is used to specify TCP and UDP traffic only. • IP is used to specify all TCP/IP protocols including TCP, UDP, ICMP and routing protocols. • Traffic can be filtered on source address only. • Traffic can…

the way to pass through data and voice. The worldwide interoperability for microwave access (technique definition of standard 802.16) implements great broadband, proto­ col independence, besides adding several services with the advantage not to de­ mand non line of sight between base stations and subscriber stations, admitting the OFDM (Orthogonal Frequency Division Modulation). Once it is a technol­ ogy for metropolitan network with superior reach of 31,07 miles to a speed of up…
