Benchmarking Latency Effects on Mobility Tracking in WSNs

The number of active nodes in a WSN deployment governs both the longevity of the network and the accuracy of applications using the network´s data. As node hibernation techniques become more sophisticated, it is important that an accurate evaluation methodology is employed to ensure fair comparisons across different techniques. Examining both energy and accuracy ensures a claim of increased longevity can be contrasted against its associated drop, if any, in application accuracy. This change can also be as a result of increased latency and the accuracy encapsulates many aspects of WSN performance in one metric. In this work, we detail the first in a series of experiments designed to demonstrate WSN trade offs using a mobility tracking application to benchmark accuracy. Additionally, we demonstrate experimental evidence for a potential adaptive mobility tracking protocol.
