In todays era there is open access wireless medium and shared nature available everywhere, where the Wireless
Networks can be attacked by the jammer easily. By this attack the real normal communication by utilizing the similar wireless
channel of legal nodes are stopped. It’s a tedious process to prevent the attack or find out the jammer location. When located an
indication of implementing anti-jamming mechanism is applied. In account of locating the jammer attacks accurately, a
discussion of existing attack localization techniques relating to gravitation locate algorithm (GLA) is applied. This heuristic
optimization evolutionary algorithm on newton’s law of global gravitation and interaction follows several steps. Also for
selecting the alternative ways Link-quality Aware Path Selection algorithm is used on finest link quality. Also various detection
algorithms such as PSO (detecting malicious node in WSN, LEACH protocol for IoT applications, distance related threshold for
CH selection , particle swarn optim
