This research is concerned with the design of Tree WSNs. This research proves that configuration plays a vital role in energy optimisation, node failure and network lifetime when designing a Tree WSN. We compare a Progressive Two Level Tree WSN with a Balanced Two Level Tree WSN. Our simulation results prove that a Progressive configuration has two advantages, over a Balanced configuration, which are less computations required to complete each process and more tolerance of node failures. These Progressive configuration advantages both lead to more energy efficiency compared to a Balanced configuration. Therefore, the lifetime of a Progressive Two Level Tree WSN is longer than that of a Balanced Two Level Tree WSN.
