line 1. INTRODUCTION Wireless ad hoc networks have emerged to support applications‚ in which it is required/desired to have wireless variety of devices without relying on communications among a any infrastructure or central management. In ad hoc networks‚ wireless devices‚ simply called nodes‚ have limited transmission range. Therefore‚ each node can directly communicate with only those within its transmission range (i.e.‚ its neighbours) and requires other nodes to act as routers in

Hello all‚ when it comes to designing a wireless network there are four steps to follow the first is the correct deployment scenario like Ad hoc or peer-to-peer‚ infrastructure‚ point-to-point and point-to-multipoint remote wireless bridge‚ Ethernet to wireless bridge‚ and wireless gate. However‚ infrastructure is the most commonly used with an access point connected to a wired infrastructure. The second step is to select the IEEE wireless network type 802.11a/b/g/n depending on what type of applications

Wireless Network A wireless network‚ as its name would suggest‚ is a network of computers and computer peripherals that are connected to each other without wires. This enables ease of communication‚ especially for mobile computing platforms. Further‚ there are a number of other advantages to a wireless network that make them increasingly common in both the workplace and at home. Nearly all wireless networks in the world work on a standard set up by the Institute of Electrical and Electronics

protection of assets. No computer system or network achieves perfect security; even a system switched off with its hard drive removed sunken in a lead case in the bottom of a deep pool in an underground facility lacks security‚ as it guarantees integrity and confidentiality but completely sacrifices availability. As a security professional‚ you must understand the risks a network faces; you must‚ in essence‚ know how to bring the network down‚ to steal the data you want‚ and to falsify important information

Manuel Castells Materials for an explorator y theory of the network society1 ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age‚ as tentatively identi ed by empirical‚ cross-cultural investigation. It permeates most societies in the world‚ in various cultural and institutional manifestations‚ as the industrial society characterized the social structure of

Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination

Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)
