Inside the paper

Portable execution starts with practical engineering.

The Next IoT Cycle explores the use of WebAssembly below the traditional application stack, bringing portable execution to microcontroller-class IoT devices. It examines a lightweight runtime, access to hardware through a common I/O interface and the toolchain constraints that shape a practical implementation.

The paper connects those engineering choices with the lifecycle of a connected product: delivering applications over the air, maintaining them over time and separating application logic from the hardware it runs on. It provides a technical foundation for evaluating portability, isolation and long-lived device applications.
