Securing Data Transfer in Delay-sensitive and Energy-aware WSNs Using the Scalable Encryption Algorithm

Due to very sensitive and crucial nature of the collected data, any wireless sensor network (WSN) has to handle efficiently securing it as well as to employ energy-aware and delay-sensitive algorithms in its all layers from application to the physical. These key topics strictly related to each other are of high importance for building and maintaining reliable and long-lasting WSN applications. However, almost none of the researches have been previously focused on them together, prompting the idea and the presented work to integrate an energy-aware and delay-sensitive centralized MAC (e.g., the EDCMAC) protocol for WSNs and contemporary encryption methods. In the simulation studies, superiority of using the SEA to the traditional AES and Skipjack has been concluded as providing much more protected data transfer and improving life-time and delay performance of the WSN applications.
