QoS based multipath routing for intrusion detection of sinkhole attack in wireless sensor networks

Wireless Sensor networks (WSN) is basically comprised of sensors that are spatially distributed with self-ruling capability, which monitors physical or environmental conditions such as, pressure, temperature, motion, sound and so on. Sensors also passes all the related information throughout the network. As the number of nodes and size of the network increases, there will be rapid increase in internet traffic. In WSN, security is the major issue and needs to a system that can provide security. Intrusion detection system is the system which plays a vital role in security of a system. One of the major challenges of WSN is to provide consistent Quality of Service (QoS) such as reliability, congestion control, energy efficiency and end-to-end delay, by applying secured routing protocols along with detection of an intruder so that QoS of WSN does not get affected. In our research work, we have discussed different routing protocols that are QoS based, to improve overall performance of the network.
