Security in Wireless Sensor Networks: A Cryptography Performance Analysis at MAC Layer

Wireless Sensor Networks (WSNs) are networks of small devices with limited resources which able to collect different information for a variety purposes. Energy and security play key role in these MAC aspects fundamental their management. The classical approaches not suitable WSNs given the nodes, subsequently require lightweight cryptography mechanisms order achieve high levels. In this paper, analysis is provided comparing BMAC LMAC protocols, determine, using AES, RSA, elliptic curve techniques, protocol best trade-off terms received packets energy consumption.
