Optimal Time and Channel Assignment for Data Collection in Wireless Sensor Networks

This paper studies the joint assignment of time slots and frequency channels in tree-based wireless sensor networks for data collection applications. Our proposed approach is based on dynamic programming and is resilient to link errors. Extensive simulations are conducted and the results show the superior performance of our approach over peer methods. In addition, our evaluation reveals the impacts of implementation-specific factors, such as link reliability, deployment area, and transmission power, making our results valuable for real-world deployments.
