Design and rapid prototyping of new medium access protocols are critical to support networked systems that are progressively reaching higher data rates with flexible use of spectrum bands. The thesis tackles both a systems and protocol fronts, developing a MATLAB-based link layer for the widely used Universal Software Radio Peripheral (USRP) software defined radios as well as designing link layer switching and medium access protocol for next generation millimeter wave (mmWave) and Terahertz (THz) bands.

520 $a Design and rapid prototyping of new medium access protocols are critical to support networked systems that are progressively reaching higher data rates with flexible use of spectrum bands. The thesis tackles both a systems and protocol fronts, developing a MATLAB-based link layer for the widely used Universal Software Radio Peripheral (USRP) software defined radios as well as designing link layer switching and medium access protocol for next generation millimeter wave (mmWave) and Terahertz (THz) bands.
520 $a We first design a state-action based 802.11 standards-compliant finite state machine (FSM) and show its operation on a real network testbed. Using a software-only approach, the user has parameter flexibility for a number of variables as well as options such as classical data-acknowledgement or request/clear-to-send modes. The design also supports other advanced features like modifying the back off window behavior and changing the channel sensing methods. To make the research reproducible and allow for extensibility by the community, the software along with a GUI is made publicly available, released under the GNU Public License (GPL).
520 $a Next, we explore a new software-defined network (SDN) framework for vehicles equipped with transceivers capable of dynamically switching between THz and mmWave bands, apart from existing classical LTE cellular bands. A novel SDN controlled admission policy that preferentially handoffs between the mmWave and THz small cells, accommodates asymmetric uplink/downlink traffic, performs error recovery and handles distinct link states that arise due to motion along practical vehicular paths is presented. A polynomial-time scheduling algorithm is designed for scheduling multiple vehicles at a given infrastructure tower, accounting for their cumulative bandwidth needs, contact times and coordination overheads.
520 $a Finally, we design a directional MAC protocol that encompasses a novel resource allocation scheme for the mmWave Vehicle-to-Infrastructure (V2I) network in an urban setting. We specifically consider a network where each Base Station (BS), equipped with hybrid beamforming antenna arrays, concurrently serves multiple vehicles. Using coherence bandwidth and coherence time specific to the mmWave vehicular channel, we provide an optimal resource allocation scheme towards efficient multi-user scheduling.
520 $a In summary, this thesis addresses several challenges in the design of medium access protocols for short-range wireless networks that can operate in distinct spectrum band(s). The publicly available code base, protocols, analytical models, algorithms and the insights resulting from simulation-based case studies will help researchers in significantly reducing the development time and effort. This will enable future reliable link layer designs and architecting robust network of radios, paving the way for the emergence of far-reaching wireless applications.
