Recent advances in the field of sensor networks helped miniaturizing nodes and, thus, enabling novel application domains for, e.g., remote monitoring or more generally the Internet of Things (IoT). One of the most critical issues in this context is the limited energy capacity of a sensor node, and its implication on communication reliability. Recently, we have investigated the use of diversity combining in a distributed sensor network to improve both the communication reliability and the energy footprint of mobile sensors transmitting to stationary receiver nodes. In this work, we go one step further and integrate the idea of preamble-less communication proposed by mSync with diversity combining to gain the added advantage of both. The elimination of preambles allows to further minimize the transmission energy. We implemented the proposed integrated model in GNURadio and evaluated its performance both in simulations as well as lab experiments. Our results demonstrate that applying diversity combining together with mSync not only reduces the energy required for transmission but also improves the communication performance in terms of Packet Delivery Ratio (PDR), especially at higher Signal-to-Noise Ratio (SNR).
