| contents | A new class of Wireless Sensor Network has emerged whereby multiple nodes transmit data simultaneously, exploiting constructive interference to enable data collection frameworks with low energy usage and latency. This paper presents STAIR (Spatio-Temporal Activation for Intelligent Relaying), a scalable, resilient framework for Wireless Sensor Networks that leverages constructive interference and operates effectively under stringent resource constraints. Using constructive interference requires all nodes to transmit the same packet at the same time, thus, only one source node can send data per time slot. STAIR uses coarse-grained topology information to flood a selected subset of the network, relaying sensor readings from individual nodes during their allocated time slots. A submodular optimisation algorithm with proven quality bounds determines near-optimal sensor activation locations and times, aiming to minimise the sum of mean squared prediction errors from a multiple multivariate linear regression model, which is used to estimate values at unselected locations and times. This framework has been extensively validated on a real-world testbed deployment. |
