Simple, extensible and flexible random key predistribution schemes for wireless sensor networks using reusable key pools
Sensor nodes are tiny, low-power, computationally limited and battery constrained electromechanical devices. A sensor node contains a sensing unit and a wireless communication unit. Sensor nodes are deployed over a field for sensing an event data in the environment and transfer it towards a base station over its wireless channel. In a typical application, vast amount of sensor nodes are deployed over a field which constitute a sensor network. Sensor nodes must be customized for a specific sensor network application before the deployment. This customization is needed not only for underlying networking application, but also for security related configurations. Random key predistribution mechanisms have been proposed to provide security for wireless sensor networks. In the literature, there are well known random key predistribution schemes. Some of these schemes are secure, but quite complex to apply in real-world applications due to their node-based customization requirements, while some other are easily applicable but they do not offer reasonable security. In this paper, we propose random key predistribution schemes for wireless sensor networks that provide varying ranges of security. The proposed schemes are easily applicable in real world scenarios due to their simplicity and relaxed node customization requirements. In this respect, our schemes provide a tradeoff. Moreover, our proposed schemes show a good extensibility property. We assume prior deployment knowledge. We examine performance of our schemes and compare them with well known random key predistribution schemes
Simple and flexible random key predistribution schemes for wireless sensor networks using deployment knowledge
Sensor nodes are tiny, low-power,
computationally limited and battery constrained
electromechanical devices that are usually deployed
for sensing some type of data in the field. Random key
predistribution mechanisms have been proposed to
provide security for wireless sensor networks. In the
literature, there are well known random key
predistribution schemes. Some of these schemes are
secure, but quite complex to apply, while some other
are easily applicable but they do not offer reasonable
security. In this paper, we propose random key
predistribution schemes for wireless sensor networks
that provide varying ranges of security and that are
easily applicable due to their simplicity. In this respect,
our schemes serve as a tradeoff. Moreover, our
proposed schemes show a good extensibility property.
We assume prior deployment knowledge. We examine
performance of our schemes and compare them with
well known random key predistribution schemes
