Abstract

In this study, we propose a novel physical layer architecture which is a hybrid of IEEE 802.15.4 and IEEE 802.11b for providing ubiquitous connectivity in IoT remote sensing platforms. The proposed architecture multiplexes the commonly available functional units of IEEE 802.15.4 and IEEE 802.11b, thereby achieving significant area and power savings. In order to achieve this, we modified the existing PHY layer to incorporate QPSK and RC pulse shaping for both the radios during the process of modulation. Performance analysis shows that the proposed architecture resulted in an area savings of 17.2 % and power savings of 17.8 % compared to traditional architecture without any performance degradation. In addition the CMOS transistors count is reduced by 6592, which is a significant reduction in complexity when compared to traditional independent radio's architectures.
