Remote node reconfiguration in opportunistic data collection wireless sensor networks

Traditionally, wireless sensor networks collect readings from distributed embedded sensing systems and forward them to one or more sink nodes. While many energy-efficient data collection protocols have emerged as a result, the transmission of control commands from a sink to individual nodes in the network is generally unsupported by these solutions. We present how the receiver-initiated opportunistic ORiNoCo data collection protocol can be extended to allow for the reconfiguration of nodes at minimal additional energy overhead. When our solution is being applied, adaptations of the sensor sampling rates or node sleep cycles can be easily controlled by the base station during runtime.
