Dynamic Application Mapping Algorithm for Wireless Network-on-Chip

Because of high bandwidth, low latency and flexible topology configurations provided by wireless NoC, this emerging technology is gaining momentum to be a promising future on-chip interconnection paradigm. However, congestion occurrence in wireless routers reduces the benefit of high speed wireless links and significantly increases the network latency, therefore, in this paper, a Dynamic Application Mapping Algorithm (DAMA) is introduced for wireless NoCs in order to reduce both internal and external congestion. DAMA has three key steps: finding the first node to map, choosing the first task to be mapped onto the first node, and allocation of the remaining tasks to the remaining nodes. Simulation results show significant gain in the mapping cost functions compared to state-of-the-art works.
