Performance Analysis of Network Layer Security Attack in WiMAX System
In the last few years there has been significant growth in the wireless communications. Security issues are prime concern in wireless communication networks. In this paper analyzed and observed the performance one of the most challenging attack i.e Black hole attacks in WiMAX-WLAN interface network. Black hole attack is very important for NGN (Next Generation Network) because this attack is very much possible in WiMAX-WLAN interface network with high impact with fewer efforts by intruder nodes. In our case study intruder node associated with less buffer size and it is moving with defined trajectory from router WiMAX-WLAN converter. In this observation there are three possibility of black hole attack has been studied i.e on the basis of less buffer size, medium buffer size and finally default buffer size. This attack is effected the performance of entire network like decrease the throughput and increase the packet dropped or delay. In last phase observed that the AP (Access Point) is highly sensitive for black hole attack with respect to buffer size.
