CDMA-Based Security Against Wormhole Attack in Underwater Wireless Sensor Networks

Abstract

The sensors are positioned below the water to monitor the underwater environment in an Underwater Wireless Sensor Network. This network is vulnerable to antagonistic environmental conditions and is more prone to attacks. Since the underwater environment begets a fluctuating nature in reference to temperature, speed, it is necessary to make the network reliable to numerous deviations. This paper suggests a detection and prevention technique for wormhole attack in Underwater Wireless Sensor Networks. Using the suggested technique, unwanted packets can be avoided at the destination node, hence decreasing the overall traffic on the network. This scenario does not consider the number of packets and also sustains against the wormhole attack. This lead to a considerable decrease in the accumulation of extra hardware at nodes. The counter function uses an easy algorithm. Therefore, to ensure the efficient functioning of the network, the error is adaptively controlled. The proposed method also improves the energy-efficiency as compared to the existing techniques.
