Input Investigation for Protection against Jamming Attacks and Routing Improvement through Taguchi’s Loss Function in MANET

Mobile ad hoc communication is a type of wireless network that has decentralized management and no infrastructure. Protection is a vital necessity in mobile ad hoc system to offer secured communication between mobile nodes. Because of specific characteristic of MANETs, it makes a selection of consequential issues to its protection design. In this particular paper we investigate number of defense mechanism against jamming attack as well as enhance the quality of community program by using Taguchi loss function calculation based. In this particular research paper we recognize several jammer attacks, current prevention and security end goal mechanism after we proposed taguchi's loss function base node drop identification & neighbour trust measurement base security measurement that proposed strategy is much better idea for communication performance improvement under security survival condition.
