| This thesis studies the suitability of low-power proprietary Radio Frequency (RF) Protocol for multi-node wireless communication. This research proposes that, instead of using standard short range wireless protocols such as ZigBee, Bluetooth, or an IEEE-articulated standard, a proprietary RF protocol is ideal for low-power communication among multiple modules avoiding co-exist interference. The thesis focuses on implementing communication architecture and analyzing different power measurements and methodologies in order to find a suitable module configuration and solve the current challenges of multi-node wireless communication and interference. A detailed communication energy model considering various system trade-offs is introduced.;The thesis presents an energy-efficient network interface architecture and a data link layer protocol for wireless networks that supports a set of parallel logical channels with unique addresses in one physical channel. Then, it shows both single and multi-radio architectures and measures their performance through a radio modeling. From these implementations and calculation, the proposed research indicates that proprietary RF Protocol provides a low-cost, power-efficient and reliable device-to-host communication as well as an efficient method to utilize multi-logical-channel configuration in the physical RF spectrum for portable communication systems.;This work also explores and confirms the possibility of implementing a radio frequency identification (RFID) system for ultra low power applications. We first consider an interference-free model, and then, extend this approach. Efficient configuration and hardware are searched to solve both power consumption and multi-node connectivity problem. |
