A Solution of Sleep Deprivation Attack in Clustered Network

With the modernization, Wireless Sensor Network (WSN) sensors are gaining importance in the real world. Though the sensor nodes have low power, sensors are widely used in detecting pollution, temperature, pressure and other various applications. Energy of wireless sensor nodes is not rechargeable. Energy-constrained sensor networks periodically place nodes to sleep in order to extend the network lifetime. Denial of sleep attack is a great threat to the lifetime of sensor networks as it prevents the nodes from going into sleep mode. There are various attacks which affect the energy of sensor node. Due to which networks life shortens. In this paper sleep deprivation attack is discussed and the prevention as to increase networks life.
