PREVENTION TECHNIQUE AGAINST DENIAL OF SLEEP ATTACK IN WIRELESS SENSOR NETWORKS

Abstract

Wireless sensor networks are unique sort of network in which mobile nodes are linked together via wireless interfaces to form a network. They don't require permanent infrastructure, because of the increased mobility of the nodes and the dynamic architecture of the Wireless sensor networks (WSN), the energy (power) of the nodes is a major concern. There are many factors which effect the proper functioning of a Wireless sensor networks but that of the attacker is fundamental because they intrude the network and attack a victim node and deplete the battery of such node which affect the performance of the network in the long run. Usually, sensor node transit to standby mode from time to time due to the Adaptive Time-out of the protocol but when such node could not enter into sleep mode, it is termed sleep deprivation or Denial of Sleep Attack. This study mitigate this attack using an algorithm at the Network Organization stage of the Wireless sensor networks which hinders intruder from penetrating into the network. Simulation was utilized to assess the algorithm's performance on a node, and the simulator was OMNET ++. The results suggest that the proposed strategy can decrease the consequences of Denial of sleep attacks in Wireless sensor networks.
