Wireless networks are based on the shared medium that makes it vulnerable to launch jamming attacks. Jamming attacks can adversely affect the normal operations of wireless networks. The existing systems for channel jamming were either adaptive for analog or were single band for a digital system. In this paper, the authors outline an approach to develop an adaptive multiband digital band hopping based anti-jamming technique. The proposed system has multiple advantages over existing systems in terms of Kaiser Windowing technique.
