Wireless Sensor Network Jammer Attack: A Detailed Review

Abstract

In todays era there is open access wireless mediumand shared natureavailable everywhere,where the WirelessNetworkscan be attacked by the jammereasily.By this attackthe real normal communication by utilizing the similar wireless channel of legal nodes are stopped.It’sa 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 optimization and several more algorithms are discussed in brief.
