A Network-based Compute Reuse Architecture for IoT Applications

In this work, we explore the use of the computation reuse concept at the edge server. We design a network-based computation reuse architecture for IoT applications. The architecture caches previously executed results and utilizes them to address newly arrived similar tasks without performing computation from scratch. By doing so, we eliminate redundant computations, enhance resource utilization, and reduce task completion time. We deployed this architecture and assessed its performance at both the networking and application levels. From the networking perspective, we achieved an up to 80% reduction in task completion time and up to 60% reduction in resource utilization, alongside a 63% decrease in energy consumption. From the application perspective, we achieved up to 90% in computation correctness and accuracy.
