A novel authentication protocol for mobile nodes in multi-base-station wireless sensor network

In order to solve the problem of the limitation of single base station network, to meet the actual needs of the mobile node authentication in multiple base station networks, the mobile node authentication protocol for multiple station networks is proposed. Mainly to solve mobile node in frequent switching between base station, which brings the problem of the certification repeat, time delay and communication load. The proposed method uses the third party media gate node, which is authorized by base station. And the neighbours list of gate node is establishment, instead of the base station to authenticate the mobile node. Experiment results show that, under a reasonable increase in the amount of storage and computational load, the proposed protocol can guarantee the mobile nodes security between base station networks.
