IMPLEMENTATION OF A MITIGATION STRATEGY FOR DENIAL OF SLEEP ATTACK AT NETWORK ORGANIZATION LEVEL IN WIRELESS SENSOR NETWORKS
Wireless sensor networks are special types of networks which use wireless interfaces to connect mobile nodes. These networks do not need fixed infrastructure. Due to high mobility in nodes and dynamic infrastructure of WSN, the energy (power) of the nodes is an important issue. There are many factors which affect the proper functioning of a wireless sensor network. However, the most fundamental is intrusion attack against a victim node and the consequent depletion of its battery. This eventually have adverse effects on the performance of the network. Adaptive Time-out of the protocol enables sensor nodes transit to standby mode from time to time. The inability of a node to enter a sleep mode is referred to as sleep deprivation or denial of sleep attack. This study proposes a technique for mitigating denial of sleep attack at the Network Organization stage of wireless sensor networks. To prevents the intruder from gaining access into the network. Simulation was used to evaluate the performance of the proposed technique. Experimental results using OMNET ++ simulator shows that the proposed method mitigates the impact of denial of sleep attacks on wireless sensor networks.
