Efficient Communication for Real-time Systems

This chapter addresses the limited bandwidth challenge that is a bottleneck for real-time data transfer. The COVID-19 pandemic has dramatically changed how we work in businesses and at home. Remote work has become increasingly common, leading to a global surge in internet and bandwidth usage. This growing demand extends beyond just video conferencing. The future of zero-emission transportation (electric vehicles), artificial intelligence (AI), edge computing (EC), software-defined networking (SDN), network functional visualization (NFV), and ubiquitous data collection across sectors like education (remote learning), health care (telemedicine), and even food delivery – all rely on a robust and fast internet connection. To meet this need, wireless communication is evolving toward 6G and beyond. However, the pace of adoption varies greatly between countries due to economic and other factors. This creates a significant “bandwidth gap” – a stark difference in internet speeds across the globe. Here is the key challenge: as technology advances toward 6G, this gap will likely persist. In any realtime data transfer scenario, the client with the lowest bandwidth acts as a bottleneck, hindering the overall efficiency of everyone involved. This is particularly evident in video conferencing, where participants join from various locations with potentially vastly different internet speeds. The result is choppy video, frozen presentations, lost packets, increased latency (delay), and even dropped connections. All of these translate to lost productivity and frustration. This research aims to develop a solution that ensures clients with limited bandwidth do not drag down the efficiency of the system and negatively impact the experience for participants with higher bandwidth capabilities.
