Trust Aware Secure Routing for Cluster-based Wireless Sensor Networks - A Comparative Study

P.Prittopaul, Dr.N.Shankarram

As wireless sensor networks is a self organizing and infrastructure less network in nature they are subject to various types of attacks on various environments. The objective of this paper is to mainly focus on a trust aware model between the communicating sensor nodes and the base station. A cluster node aggregates the data from other sensor nodes and eradicates the disused data, disseminates the used data to the base stations that are one hop distance from the node. Since base stations acts as an interface between the communicating sensor devices, the nodes are subject to various attacks on various layers. Here a comparative study is made on various types of attacks on a clustered environment and little available trust aware models are also discussed that defence against the various types of attacks that induces harm between the sensor nodes and base stations.
