In wireless sensor networks (WSNs), hierarchical routing protocol is commonly used for energy efficiency. However, routing protocols without proper security suffer from many security vulnerabilities. Hence, in this paper, we propose a key renewal scheme based on clustering routing protocol. Especially, this scheme updates the key considering the amount of communication. The simulation result shows that the transmission probability goes up normally after renewal the key when network lifetime is decreased only 9% compared with the case of symmetric key without key renewal scheme.
