Transmission power levels Prediction for Distributed Topology Control Protocols within parameterized scenarios

Distributed topology control protocols (DTCP) for wireless sensor networks (WSN) coordinate nodespsila decisions regarding their transmission ranges, in order to set up a network with a certain connectivity, while reducing nodespsila energy consumption and/or increasing network capacity. The key issue in DTCP is to choose the most suitable transmission power level (TPL) among those available for each sensor node in a distributed manner. We present a method to predict the TPLs for DTCP in realistic scenarios, which takes into account several propagation phenomena, such as barriers and multipath interference. To evaluate the effectiveness of our approach, we simulated the radio propagation pattern of a WSN in a scenario of multiple rooms. Our results suggested that our method allows to predict, with reasonable accuracy, the approximate TPLs distribution achieved by different DTCP approaches within a given parameterized scenario.
