Secret key encryption model for Wireless Sensor Networks
Abdullah Khan, Syed Waqar Shah, Abdar Ali, Rizwan Ullah · 2017
The limited energy, memory and computational power of sensor nodes in wireless sensor networks presents a challenging environment for designing. In this paper, secret key encryption is proposed for wireless sensor networks keeping the constraint environment. The proposed candidate for secret key encryption is Advance Encryption Standard (AES) and the proposed coding scheme is Low Density Parity Check which will reduce computation and energy consumption. Petri Nets is used to present simplified communication model of proposed scheme. BER results over AWGN and fading channel of peer to peer link also included in paper and an improvement of 33.44% in BER has been achieved over fading channel.
