The use of monitoring sensors is increasingly present in the context of precision agriculture. Usually, these sensor nodes (SNs) alternate their states between periods of activation and hibernation to reduce battery usage. When employing unmanned aerial vehicles (UAVs) to collect data from SNs distributed over a large agricultural area, we must synchronize the UAV route with the activation period of each SN.

- Underwater acoustic networks (UAN) effectively monitor and exploit underwater environments but face challenges like long delays and error-prone channels.
- The paper focuses on enhancing communication efficiency by optimizing channel coding parameters, specifically using a two-layer encoding scheme with forward error correction (FEC) codes and fountain codes (FC) for scenarios without feedback.
- The authors model energy consumption for various coding schemes and find optimal parameters based on link distance and signal quality, resulting in recommendations for the most effective configurations.
