Networked sensor systems (NSS) have the potential of significantly enhancing our ability to monitor and interact with our physical environment. For example, numerous tiny sensors may be spread all over a forest to reveal the forest's life and events in detail along the time-space continuum. Critical to the success of NSS is the reliable collection and dissemination of data while conserving sensors' limited resources, in particular energy. In this paper, we propose a novel scheme that provides fault-tolerant data collection and dissemination through data checkpointing and recovery. We assume that the data is periodically reported from a sink node to the end users. Based on a model-based simulation, we show that our scheme is highly resilient to sensor and sink failure. It also leads to enhanced NSS lifetime and data collection with minimal overhead.
