With the advent of mobile technology, the wireless communication is becoming more popular than ever before. This is due to technological advances in wireless data communication devices. A primary requirement for the establishment of communication between two devices is that intermediate nodes should cooperate with each other. Presence of malevolent nodes may lead to serious security concerns. Preventing and detecting malicious nodes and attacks is a challenge. This Paper attempts to resolve this issue by designing a Cooperative Bait Detection Scheme (CBDS) that has advantages of both proactive and reactive defense architectures.
