Design-time decisions can often only cover certain scenarios and fail in efficiency when hard-to-predict system scenarios occur. This drives the development of run-time adaptive systems. To the best of our knowledge, we are presenting the first scheme for a runtime application mapping in a distributed manner using agents targeting for adaptive NoC-based heterogeneous multi-processor systems. Our approach reduces the overall traffic produced to collect the current state of the system

In our experiment, we obtain 10.7 times lower monitoring traffic compared to the centralized mapping scheme proposed in [8] for a 64×64 NoC. Our proposed scheme also requires less execution cycles compared to a non-clustered centralized approach. We achieve on an average 7.1 times lower computational effort for the mapping algorithm compared to the simple nearest-neighbor (NN) heuristics proposed in [6] in a 64 × 32 NoC. We demonstrate the advantage of our scheme by means of a robot application and a set of multimedia applications and compare it to the state-of-the-art run-time mapping schemes proposed in [6, 8, 19] .
