Energy Consumption in Key Management Operations in WSNs

This paper gives an illustration and demonstration of mathematical model of new key management scheme which overcomes the limitation of Pre-Shared key scheme in terms of energy consumption using various key management operations in WSNs. Various key management operations were recorded and evaluate based on energy consumption at each step of authentication in wireless sensor network which improves that NchooseK Scheme is more scalable and secure than PSK in terms of energy consumption in WSNs.
