| Summary: | wireless network on-Chip or WiNoC is an alternative to traditional planar on-chip networks. On-chip wireless links are utilized to reduce latency between distant nodes due to its capability to communicate with far-away node within a single hop. this paper analyzes the impact of various routing schemes and the effect of WiNoC sizes on network traffic distributions compared to conventional mesh NoC. radio hubs (4x4) are evenly placed on WiNoC to analyze global average delay, throughput, energy consumption and wireless utilization. For validation, three various network. sizes (8x8, 16x16 and 32x2) of mesh NoC and WiNoC architectures are simulated on cycle-accurate Noxim simulator under numerous traffic load distributions. Simulation results show that WiNoC architecture with the 16x16 network size has better average speedup (~1.2x) and improved network throughputs by 6.36% in non-uniform transpose traffic distribution. However, as the trade-off, WiNoC requires 63% higher energy consumption compared to the classical wired NoC mesh. |
