How to accurately and rapidly detect traffic attack is an important security problem in wireless sensor networks. An energy-saving ARMA-based traffic attack detection protocol is proposed in this paper. The detection protocol uses linear prediction to establish easy ARMA(2,1) model for sensor nodes. In the detection protocol, different nodes play different roles, and use different monitor schemes...
Directed diffusion is a data dissemination protocol for wireless sensor networks. In directed diffusion, interest and exploratory data are disseminated by flooding, which will bring broadcast storm resulting in substantial energy consumption of networks. Grid-based directed diffusion can improve the energy efficiency where geographic grids are constructed by self-organization of nodes using location...
