Attack Detection Model Based on Routing Protocol in Wireless Sensor Networks

To the specific features of wireless sensor network and attack models met with routing protocols,this paper presents an attack detection model of combined distribution based on grey theory(GADM).Utilizing features of grey theory that less data is needed in model construction,and method that each node undertakes detection tasks,this model will save energy consumed in attack detection.Through data collection and analysis on each node and combined detection and response between nodes,attack behavior can be forecasted and a forecasting model on attacks for wireless network is constructed,therefore security of routing protocols is effectively improved.It provides frameworks of the attack detection model and specific process of formulation for constructing the model.An emulation experiment proves the affectivity of the model.
