Jamming Threat To Wireless Sensor Network

Abstract

Assurance of security in wireless sensor networks is a difficult task as the sensor networks suffers from limited operating and energy resources. There are several types of denial of service attacks in these networks, but jamming attack is the most severe one. It disturbed the normal transmission of information by reducing the signal to noise ratio. With the help of jammer, radio signals are transmitted towards victim node or the channel. In this work, we analyze different types of jamming attacks which affects the sensor networks. A survey on avoiding jamming attack has been conducted by analyzing signal strength, and packet delivery ratio etc.
