An Authentication Protocol for Hierarchy-Based Wireless Sensor Networks

Hierarchy-based Wireless Sensor Networks (WSNs) achieve excellent performance with reserving energy consumption and decreasing system delay. However, distinguished hierarchy-based research such as LEACH (Low-Energy Adaptive Clustering Hierarchy) does not consider a security issue for ensuring the protection of the network. Due to the peculiar character of LEACH such as round base operation and header centrality topology, adopting security in LEACH is a complicated task. In this paper, the authors present an authentication protocol for hierarchy-based WSNs to protect network from inside attackers.
