Secure routing methods for clustered hierarchical WSN based on the trusted cloud

How to energy efficiently guarantee secure routing for wireless sensor network has always been a huge challenge. A trusted cloud-based secure routing algorithm (TC-SRA) for a clustered hierarchical wireless sensor network was proposed, which built a secure framework based on trust cloud for wireless sensor network, and all nodes in network can be efficiently managed by the clustered hierarchical topology. The routing performance of wireless sensor network is improved from the view point of both energy efficiency and security. The results from simulation test show that the proposed algorithm not only provides a new path for routing security of wireless sensor network, but also can effectively save energy consumption of nodes and hold the lifetime of network.
