Due to the openness of the wireless transmission medium, it is easy to launch spoofing attack and can significantly reduce the performance of networks. Among various types of attacks, identity-based spoofing attacks are especially easy to launch and can cause significant damage to network performance. This paper proposes a mechanism for detecting and preventing these harm full attacks. This mechanism is based on physical data which include IP address, MAC address and signal strength values reported by access point to detect spoofing attack.
