Max-Heap Based Leach Protocol Using Homomorphic Encryption
Encryption schemes that support operations over cipher text are of utmost importance for wireless sensor networks and especially in Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. Energy is salient limit of LEACH. Due to this limitation, it seems important to design a confidentiality scheme for WSN so that sensing data can be transmitted to the receiver securely and efficiently and at the same time energy consumed must be minimum. Hence, the authors proposed LEACH-HMH in which confidentiality scheme i.e. homomorphic encryption and max-heap i.e. load balancing is added to LEACH protocol.
