Environmental monitoring with wireless sensor networks (WSNs) is based on an infrastructure with unreliable communication channels and nodes. WSNs, also, have a limited lifetime due to the fixed energy budget. Nevertheless, the user of a data-storing WSN often needs high availability of the measured data. But unfortunately, there is no conceptional(More)

In a pervasive environment, wireless sensor networks are one backbone for the interaction with the real world. Therefore, pervasive computing relies on a networked infrastructure with an inherent high dynamics due to mobility of nodes, unreliable communication channels and node failures. Additionally, wireless sensor networks are a class of networks with a(More)
