Reliable and Efficient Routing in WLAN
International Journal of Trend in Scientific Research and Development
The rapid need of wireless demands a great deal of security and reliable routing in order to keep all the data sources and equipments secure. In order to develop efficient and robust protocols, it is essential to understand the inherent characteristics of wireless networks such as connectivity, coverage and varying channel conditions. Wireless LAN introduces the concept that use can connect to any one at any place at anytime by using various mobile appliances that can be carried at any place.
... w Communication is no longer limited to a one place by holding wired phones. This is the big boom to the I.T industry but it also brings a lot of opportunities and challenges for the Network Administrator who is looking after the Wireless LANs (WLAN). WLAN traffic travels over radio waves that cannot be constrained by the walls or any obstacle that comes in his line of direction. So because of this hackers can easily hack that material that is been transferred from different nodes. . In wireless LAN, Denial of Service or Jamming is caused by disrupting or denying the communication between sender and receiver. So for this reason the SNR is decreased at the receiver end. To understand how the signals are getting weak and how the jammer attacks the wireless LAN so that network performance drops down significantly. It is important to develop some powerful tools for network analysis, design and managing the performance optimization of the network. In this paper some of the most common attacks and threats are explained and the prevention that can be taken by using various tools is implemented. All the nodes and the attacks are been shown by using a simulator NS2.
