Comparative Analysis of the Prevention Techniques of Denial of Service Attacks in Wireless Sensor Network

Wireless ad-hoc sensor network is gaining popularity in all organization and it is basic means for communication. Wireless ad-hoc sensor network is vulnerable to Denial of Service (DOS) attack.DOS attack make the network resources is unavailable to users. In DOS attack it makes the node to consume more battery power and degrades the network performance. Various techniques are used for detection and prevention of DOS attack such as spread spectrum, packet leash, lightweight Secure Mechanism and energy weight monitoring system but DOS attack cannot fully prevented using this techniques. This paper reviews various types of DOS attacks and its Detection techniques.
