Key Management in Static and Mobile Sensor Networks

Abstract

Wireless sensor networks consist of sensor nodes with limited computational and communication capabilities. These networks are dynamic in nature that they allow addition of nodes to the network thus increasing the size of the network over time. The nodes communicate with each other in a secure manner and send processed data to the base station. This thesis concerns Key management in static and mobile sensor nodes. The network of sensor nodes is divided into clusters based on their physical locations in both cases. In addition, efficient ways of key distribution among the nodes within the cluster and among heads of clusters are discussed. The security of the network is considered through efficient key management by taking into consideration the network's power capabilities is discussed.
