Detection&Prevention of DDoS and Flooding Attacks in Ad hoc Network

Many organizations are using LAN (local area network) to access the internet, this enable the work in many industries easy and comfortable. Flooding and D-DOS are the two major threats to WLAN because these two effects causes huge amount of interchange. The two threats are very difficult to detect and resolve because it involves huge network traffic, In this paper we are introducing a broadcast technique to overcome and prevent flooding attack. We are using two techniques to overcome these problems. This work involves two techniques (AVERAGE DISTANCE ESTIMATION) and (RATE LIMITING). AVERAGE ESTIMATION involves estimation of distance and RATE LIMITING involves different controlling units to encounter (DISTRIBUTED DENIEL OF SERVICES) attack. Regular distance estimation technique study and examine the distance values for noticing the hidden solution for controlling D-DOS. The mean values of distance are forecast to define normality in (AVERAGE ESTIMATION). The mean absolute deviation method is used which includes (MAD) technique to distinguish normality from the abnormality.
