Adaptive communication strategies

Definition

Adaptive communication strategies refer to techniques that allow wireless sensor networks (WSNs) to dynamically adjust their communication protocols and data transmission methods based on changing environmental conditions, network topology, and energy constraints. This adaptability enhances the network's efficiency, extends its lifetime, and improves the reliability of data delivery, which is crucial for the effective functioning of distributed learning algorithms.
