Byzantine Attacks in Energy Constrained Wireless Sensor Networks

Byzantine attacks disrupt the communication between nodes in the network without regard to its own resource consumption. In Wireless Sensor Networks (WSN) the wireless shared medium is susceptible to attacks; also communication is the biggest source of energy consumption in WSN. The jamming of physical layer, disruption of MAC layer, control packets, attack against routing, attacks on transport protocol etc. The performance of nodes in wireless sensor networks is critical because of limited power. This paper discusses the performance of WSN under byzantine attacks and their mitigation by using advanced node as cluster head and proposed protocol. Results have shown improvement in energy efficiency in WSN.
