Abstract :

A wireless sensor network (WSN) is a network of spatially distributed autonomous sensors to monitor physical or environmental conditions and passage of data through the network to a base station. The WSN is built of "nodes" – from a few to several hundreds or even thousands, where each node is connected to one (or sometimes several) sensors.DoS attacks disrupt the entire or a part of WSN network. Detection and avoidance of DoS attacks is necessary. We provide a technique for the same.Nodes are grouped into clusters which have a cluster head which has information about the nodes under it. This paper intends to implement common key authentication mechanism by which cluster head as well as any other sensor nodes in network can identify the communicating node as an attacker node or not. Authentication server will send common key to all nodes and cluster heads. For successful communication, hash codes of the requesting sensor node and cluster head need to match. If they don’t then node is said to be attacker. A new key will then be generated and distributed across the all nodes except attacker node. Aim is to make system efficient.
