Multi-Tree Network Protocol Enabling System Partitioning for Shape-Changeable Computer System

Published: 02 July 2024 Publication History

Abstract

Shape-changeable computer system is proposed as a system that forms various shapes by communicating wirelessly with many adjacent chips. A network that supports diverse shapes and dynamic chip replacement is important, and methods for constructing ad-hoc wireless networks and enabling dynamic reconfiguration of the system at runtime have been proposed so far. However, there is room for improvement in performance because they are based on up*/down* routing. Moreover, system partitioning is required by applications such as micro-robots and shape-changing user interfaces, and no network that realizes this has been studied yet. In this study, we propose a multi-tree network construction method for improving routing performance and a protocol that enables system partitioning, and we verify them by simulation using a newly-developed simulator.
