Trust Management Based Intrusion Detection in Wireless Sensor Networks

Mr.R.Mohan Kumar, Dr.A.V.Ramprasad

In wireless sensor network (WSN), intrusion acts as a serious threat impairing the network, it is necessary to refrain from these attacks by the detection of intrusion which turns out to be a challenging task. Apart from these hazards there prevail other kinds of deterrent attacks. The overall intrusion can be curbed down by80%. In this work , consider trust based nodes in a route for transmission of information from the source to destination. The centralized and decentralized wireless sensor networks are taken into account through which the trust behaviors of nodes are determined. In decentralized wireless sensor network, the leader or cluster head is designated based on the energy levels of the nodes. Region wise election is established for the selection of the cluster head or leader depending on the factors of runtime, area and energy. A trust management protocol is deployed which facilitates the analysis of trust behavior of nodes in a route .In our approach , use a centralized wireless sensor networks, such that a single leader is responsible for collecting all information of sub leaders and if intrusion evolves in the network, it overcome by transmitting the data through these trustable nodes. The intruders in the route are found by using a intrusion detection system protocol (IDSP) thereby by eliminating degradation of transmission.
