Abstract
As the Internet of Thing (IoT) trend, cloud technology, and big data analysis technology grow, the wireless sensor network is introduced for the in-house IoT scenario. In this thesis, we design both the communication protocol and the transmission hardware together to optimize the overall system performance. Due to the cross-layer design, the interface problem becomes an important issue. Besides, a systematic analysis of a simple network architecture is conducted to find the optimal operational point of the protocol design, given the hardware parameters. In other words, a model considers the clock drift, BER vs SNR, the synchronization error, the sync. frequency, the sync. margin, fail packet statistics and so on, is proposed as a guideline for wireless communication network design. Moreover, a cost function in algorithm field and the Energy Per Byte Index (EPBI) are introduced to evaluate the performance in the perspective of power consumption V.S. data rate. Most important of all, most of the parameters in the analysis are based on the measurement result and hence are much more realistic for the integrated system design in practical. In short, a design rule for the wireless sensor network design is proposed and an optimal protocol parameter set in the perspective of power consumption is found for a fixed specification of the adopted hardware, which meets the low power consumption trend of the IoT application.
