    abstract = {Data aggregation protocols are required in Wireless Sensor 
  Networks (WSNs) to extend the network lifetime by reducing the energy consumption. 
  The existing DAO-LEACH (Data Aggregation-Optimal LEACH) protocol for WSN is 
  insecure and prone to false data injection. This is enhanced in terms of security 
  and fault-tolerance based on Gracefully Degraded Data Aggregation (GDDA) to 
  ensure the integrity of the aggregated data and Hybrid Layer User Authentication 
  (HLUA) to ensure the confidentiality of the aggregated data. This data aggregation 
  scheme rejects the false data from compromised and malfunctioning Sensor Nodes 
  (SNs). HLUA consists of a combination of Secret Key Cryptography (SKC) Method 
  such as MAC (Message Authentication Code) algorithm and Public Key Cryptography 
  (PKC) Method such as Elliptic Curve Cryptography (ECC). MAC algorithm is used 
  between the Cluster Heads (CHs) and SNs to fulfill lower power demand while 
  ECC is applied for User Authentication (UA) between CHs and users. The enhanced 
  DAO-LEACH protocol is resistant to security attacks such as replay attacks, 
  node compromising attacks and impersonation attacks. It performs better in terms 
  of energy consumption, number of alive nodes, End to End Delay (EED) and false 
  data detection, compared to SCAR (Simple Cluster-based data Aggregation and 
  Routing), ESPA (Energy-efficient Secure Path Algorithm), DKS-LEACH (Deterministic 
  Key management based LEACH), SEDAN (Secure and Efficient Data Aggregation protocol 
  for WSNs) and DAA (Data Aggregation and Authentication).}
