In this paper, we propose a new security protocol for a wireless sensor network, which is designed for monitoring long range power transmission lines in smart grid. Part of the monitoring network is composed of optical fiber composite over head ground wire (OPGW), thus it can be secured with conventional security protocol. However, the wireless sensor network between two neighboring OPGW gateways...
In this paper, we introduce a security protocol for wireless sensor network which is designed for monitoring long range power transmission lines in smart grid. The proposed security protocol provides authentications to the sensor nodes and the information data, and the encryption for uplink and downlink information of the power line monitoring sensor network. Different from the existing protocol,...
