Mesh Networking in transiently-powered systems

Abstract

This thesis focuses on the idea of simultaneous wireless information and power transfer (SWIPT) for carrying the information and energy altogether at time domain specifically. This is done, by using the scheme of time switching (TS) on the side of receiver that separates into two modes. The first mode is the transportation of energy and the second mode is the forwarding of information over the incoming radio frequency (RF) signal. On this basis, the linked antenna is formalized over the transceiver system, which mix the transmitter and the receiver into one system. By assuming the generated frequency of 5 GHz, the power is transmitted at 10 and the distance among the circuits of (EH) energy harvesting and (ID) information decoding is 4 meter (m), which is between transmitter and receiver of these two circuits. Directing the incoming electrical signal by either modulating or demodulating it within the scope of frequency shift keying (FSK) theory. On one hand, the EH circuit is responsible for filtering the RF signal within two operations. One, is a passive band pass filter circuit and the second one is the rectifier circuit that transforms the electrical carrier into direct current (DC). Hence, the signal is moved and placed in the energy storage to hold the energy to be used later on with ID. On the another hand, the ID circuit is deployed to convey the inputted message by switching from the first circuit to the second circuit after the storage is charged. This requires the energy from the storage to send information in a given time slot to be switched all together to achieve the TS scheme.
