Abstract: Current research on the Wireless Sensor Network (WSN) routing protocols considers little about the safety of the routers, or merely proposes key management algorithm without combing the practical net model with the algorithm. Therefore, the authors proposed a secure routing algorithm based on hierarchical and level-administration which guaranteed the alive-time as well as the security. In the algorithm, nodes were clustered by level-administration, information was transmitted from low to high level by level, redundancies were reduced by data merging. By combing level-administration and distributed approach to security in sensornets (DSPS) key management, the energy consumption of key management was greatly reduced, which not only extended the alive-time of the network, but also guaranteed the security of the network. Finally, the experimental results in NS2 indicate that this algorithm is suitable for large-scale WSNs, and balances the nodes energy consumption and extends the alive-time of the network.
