This chapter presents an instruction set architecture (ISA) dedicated to the rapid and efficient implementation of single-channel IoT communication interfaces. The architecture is meant to provide a programming interface for the implementation of signaling protocols based on the recently introduced pulsed-index schemes. In addition to the traditional aspects of ISA design such as addressing modes, instruction types, instruction formats, registers, interrupts, and external I/O, the ISA includes special-purpose instructions that facilitate bit stream encoding and decoding based on the pulsed-index techniques. Verilog HDL is used to synthesize a fully functional processor based on this ISA and provide both an FPGA implementation and a synthesised ASIC design in GLOBALFOUNDRIES 65nm. The ASIC design confirms the low-power features of this ISA with consumed power around 31µW and energy efficiency of less than 10pJ/bit. Finally, this chapter shows how the basic ISA can be extended to include cryptographic features in support of secure IoT communication.

Pulsed-Index Communication (PIC) is a recent technique for single-channel communication that is based on the principle of transmitting the indices of only the ON bits as a series of pulse streams. In this paper, a modified version of PIC, called Pulsed Decimal Communication (PDC), is presented that uses the same underlying principle but with key improvements in data rate and reliability. Like PIC, PDC is a protocol for single-channel, high-data rate, low-power dynamic signaling that does not require any clock and data recovery. It consists of a three-step algorithm, comprising a segmentation, an encoding, and a sub-segmentation step to achieve higher data rates. The segmentation step splits the data word into smaller segments and therefore smaller decimal numbers to represent them. The encoding step reduces the number of ON bits in the data and relocates them to lower indices. The sub-segmentation step further splits the segments into smaller sub-segments. The complete process significantly reduces the total number of pulses required for transmitting binary data, thus improving the data rate by about 78% . A theoretical model of the PDC protocol is exploited to estimate its data rate and derive the optimum segmentation. Furthermore, PDC is shown to be more reliable than PIC as it eliminates the variations in the number of symbols to be transmitted. The FPGA and ASIC (65nm technology) implementations of PDC show that the low-power operation and small footprint of PIC are preserved. PDC consumes around 25µW of power at a clock frequency of 25M Hz with a gate count of approximately 2150 gates.

In this article, the design and performance analysis of wireless body area network-based systems for the transmission of medical information readable in an android-based application deployed within complex indoor e-Health scenarios is presented. The scenario under analysis is an emergency room area, where a patient is being monitored remotely with the aid of wearable wireless sensors placed at different body locations. Due to the advent of Internet of Things, in the near future a cloud of a vast number of wireless devices will be operating at the same time, potentially interfering one another. Ensuring good performance of the deployed wireless networks in this kind of environment is mandatory and obtaining accurate radio propagation estimations by means of a computationally efficient algorithm is a key issue. For that purpose, an in-house three-dimensional ray launching algorithm is employed, which provides radio frequency power distribution values, power delay profiles, and delay spread values for the complete volume of complex indoor scenarios. Using this information together with signal-to-noise estimations and link budget calculations, the most suitable wireless body area network technology for this context is chosen. Additionally, an in-house developed human body model has been developed in order to model the impact of the presence of monitored patients. A campaign of measurements has been carried out in order to validate the obtained simulation results. Both the measurements and simulation results illustrate the strong influence of the presented scenario on the overall performance of the wireless body area networks: losses due to material absorption and the strong influence of multipath components due to the great number of obstacles and the presence of persons make the use of the presented method very useful. Finally, an android-based application for the monitoring of patients is presented and tested within the emergency room scenario, providing a flexible solution to increase interactivity in health service provision.
