Secure Data Communication in a Clustered Network in Wireless Sensor Networks using AES Cipher

Data is collected and forwarded to the cluster head by sensor nodes in the Wireless Sensor Network (WSN). Ensuring the confidentiality and integrity of the data that must be provided to the base station is tough. We recommend using a simple Caesar cipher and Advanced Encryption Standard (AES) technique at the cluster head node level for effective communication from the cluster head to the base station with little power consumption
