The success of the Internet of Things (IoT) relies on the efficient provision of wireless connectivity to numerous machine-type devices. Future wireless systems must effectively and efficiently support the machine-type communications (MTC) with diverse quality of service requirements. The long-term goal of the proposed five-year research program is to develop an integrated wireless transmission solution for future IoT that can simultaneously i) support ultra-reliable low latency transmission for mission critical MTC; ii) connect massive MTC terminals with extremely high energy efficiency; and iii) achieve highly-secure physical data transmission. We adopt a novel data oriented approach in the design and analysis of advanced wireless transmission technologies. Unlike the conventional channel-oriented approach, we directly optimize the transmission strategies for individual transmission sessions, considering both traffic characteristics and instantaneous operating environment. The design from this extremely original approach can effectively satisfy the stringent performance and efficiency requirements of future IoT applications. This data-oriented approach will also facilitate the integration of different transmission technologies into a common physical transmission infrastructure. Following the innovative data-oriented approach, we carry out the proposed research in three major steps to advance towards our long-term goal. In the first step, we develop theoretical performance limits for individual data transmission sessions in terms of reliability, energy efficiency, and security. This step will involve the definition of suitable data-oriented performance metrics and extensive statistical analysis for various transmission scenarios. In the second step, we will design practical transmission strategies to approach theoretical performance limits. We will apply various advanced optimization and machine learning tools to arrive at the most efficient transmission strategy for given transmission scenarios under practical implementation constraints. In the final step, we will examine the integration of newly developed transmission technologies into existing/emerging wireless systems. The successful completion of the proposed research program will have a ground-breaking impact on future wireless communications and greatly facilitate the success of future IoT. The data-oriented approach will generate profound new insights to wireless system design and engender cutting-edge transmission strategies. The resulting transmission solution together with newly-enabled IoT applications will bring huge social and economic benefit to Canada. The highly qualified personnel (HQP) trained through this program will possess essential technical skills for the design and analysis of advanced wireless transmission technologies, and as such, can make significant contribution to the Canadian information and communication technology (ICT) sector.
