Intrusion detection system in wireless sensor network

Abstract

The constant growth in network industry has put forward some queries regarding vulnerability and security of a computer network. Intrusion detection is the mechanism of identifying the unauthorized packets that enter an organization’s network. It acts as a shield and informs the system administrator when some unwanted traffic is seen to flow inside. The intrusion detection system has a lot of challenges; it must look up the event log and try to classify the packets that are malicious. A wireless sensor network (WSN) is one which consists of manylow-costnodes, whose position are not fixed in a network and are subjected to change.The main aim of this paper is to simulate intrusion in a WSN and perform a comparative analysis between a network without intruder, with intruder and an enhancement of the later in following parameter: throughput, average delay in transmission, packet drop ratio and overhead.
