Abstract : Decades of software engineering shows that updating deployed software is not a nice-to-have, but a must-have. Deployed software (e.g. an IP protocol stack) is never bug free, and these bugs must be patched to increase its robustness and security, and as communication standards and application logic evolve, deployed software typically needs to evolve in parallel. As the IoT emerges, the same will apply to deployed IoT software.
