Internet of Legacy Devices (I-oLD): Harnessing the Potential of Outdated Mobile Devices

The rapid turnover of mobile devices, driven by social pressure and frequent market releases, leads to large numbers of smartphones becoming outdated yet still technically capable, retaining considerable computational power, memory, and sensing capabilities. We propose the Internet of Legacy Devices (I-oLD), an open framework designed to abstract the heterogeneity of old hardware, aiming to recycle and repurpose these devices, leveraging their residual computing power, sensors, and displays for distributed computing, modular interfaces, and pervasive sensing. This approach reduces electronic waste, promoting sustainable "green"computing, and provides low-cost hardware solutions for researchers, developers, and users worldwide.
