Our project based on mitigating the channel jamming in wireless network by detecting the jamming attack on channel using GUIDE algorithm. We assign the spread code to each one of the customer as a unique code,there by we can block the intruder. Here we achieve a feature that the message passing can be done quickly by sending them through random channel port. Thus we develop the system with high degree of confidentiality that efficiently detects and mitigates the jamming in wireless network
