Full network level privacy spectrum comprises of identity, route, location and data privacy. Existing privacy schemes of wireless sensor networks only provide partial network level privacy. Providing full network level privacy is a critical and challenging problem due to the constraints imposed by the sensor nodes, sensor networks and QoS issues. In this paper, we propose full network level privacy solution that addresses this problem. This solution comprises of Identity, Route and Location (IRL) privacy algorithm and data privacy mechanism, that collectively provides protection against privacy disclosure attacks such as eavesdropping and hop-by-hop trace back attacks.
