A Secure and Energy-efficient Rooting Protocol for WSN
In directed diffusion rooting protocol,interest and exploratory data are disseminated by flooding,which will bring broadcast storm resulting in substantial energy consumption of wireless sensor networks.Grid-based directed diffusion rooting protocol can improve energy efficiency where geographic grids are constructed by self-organization of nodes using location information.Flooding of interest and exploratory data is limited in grid head nodes.But grid-based directed diffusion roofing protocol considers less about security.To adapt to environments with high security requirements,traffic attack detection and secure data aggregation schemes are added to grid-based directed diffusion rooting protocol.Simulation shows that the proposed schemes can real-time predict traffic attacks and improve accuracy of data aggregation results when networks are under attacks.At the same time,the protocol consumes less energy and extends lifetime of networks.
