Abstract


With wireless sensor networks having become a tool of choice for a wide range of measurement and monitoring purposes, precise time synchronization is consequentially gaining prominence. Various protocols and synchronization methods are used to achieve the “sweet spot” amongst the accuracy, synchronization speed, and energy consumption of the network. In this paper, we have evaluated the device and modulation specific packet transmission uncertainty, eliminating all possible protocol related uncertainty sources. We have determined that the transceiver hardware dependent time, taken to transmit and receive the packet, not only depends on the transceiver model, but also highly dependent on the modulation. Moreover, sometimes transmission time distribution does not behave per the standard distribution model and seems to be additionally dependent on the internal processing logic of the device.
