Wireless sensor networks have received wide attention recently across indoor and outdoor applications. One the other hand, more and more application scenarios require sensor nodes to be mobile, which introduces new technological challenges for security. Key management is the core for secure data communications among resource-constrained sensor nodes. In this paper, based on Group Diffie-Hellman key agreement protocols and the energy level of each node in the network, we propose Energy Aware Group Diffie-Hellman key management protocols for mobile wireless sensor networks. Simulation results show that the proposed key management protocols provide a great improvement in maximizing the lifetime of networks.
