Multilayer perceptron based secure media access control protocol for wireless sensor networks

This paper discusses an application of multilayer Perceptron in wireless sensor network security. The wireless sensor network (WSN) is a network of distributed autonomous devices that supervise physical or environmental conditions corporately. The multilayer perceptron (MLP) based media access control protocol (MAC) to secure CSMA-based wireless sensor networks against denial-of-service attacks launched by adversaries. The MLP boost security of a WSN by consistently monitoring the parameter that reveals unusual variation in case of an attack the MLP alerts the MAC layer and the physical layer of the sensor mode when the suspicion factor, the output of the MLP exceeds a preset threshold level. Back propagation and Radial Basis Function Network (RBFN) algorithms are used for training the MLP. Simulation results show that the MLP helps in extending the life time of the WSN.
