Protocols to Orchestrate Reconfigurable Graphene Antennas at the Chip Scale

Develop medium access control and networking protocols for wireless networks within computing packages that actively manage the reconfigurability of graphene-based nano-antenna arrays, including dynamic beam steering and frequency tuning, to orchestrate the available space–time–frequency channels at the chip scale while meeting the ultra-low latency and very low bit-error-rate targets required by chip-scale systems.

Background

The paper envisions electromagnetic nanonetworks inside computing packages using compact, beam-steerable, and frequency-tunable graphene antennas. While this hardware capability exists conceptually, current wireless chip-scale proposals based on conventional on-chip antennas lack dynamic beam-steering and frequency tuning.

Consequently, there are no existing protocols that can orchestrate space–time–frequency channels offered by reconfigurable graphene antennas with the simplicity required at the chip scale. This gap in the stack is identified as an open issue directly tied to exploiting graphene’s reconfigurability for performance and flexibility gains in computing systems.

This represents an open issue as none of the existing wireless chip-scale networks proposals, e.g. [Shamim2017], support dynamic beam-steering or frequency tuning simply because conventional on-chip antennas cannot have such capabilities. In other words, there are no protocols in the literature that can orchestrate the space-time-frequency channels offered by graphene antennas with the simplicity needed at the chip scale, while adapting to the traffic requirements.
