Analyzing Energy Consumption by Cryptographic Techniques for Secure Communication in Underwater Wireless Sensor Networks

Underwater Wireless Sensor Networks comprise of a spread of acoustic sensors or nodes deployed in a geographical area of interest under the sea or ocean. The nodes on capturing data from the particular region send it to a central processing point. Due to the characteristics of underwater channel, these types of senor networks are vulnerable to malicious attacks. Being battery powered, energy is an important and critical factor to be considered for underwater sensor networks, along with maintaining the security of data. This paper aims at analyzing the energy consumed by cryptographic algorithms, applied in routing data in a clustered manner, in this category of wireless sensor networks.
