Networks-on-Chip (NoC) is an effective solution to inside on-chip communication problems. In recent years, the advancement of silicon industry and also the production of Carbone Nanotube antennas (CNTs), it is possible to use wireless antennas in the network on chip. This new communication structure is called a Wireless Network on Chip (WiNoC). Using the wireless antenna in multi-core chips led to the reduction in the latency and power consumption. In spite of higher bandwidth of the WiNoCs compared to wire NoCs; their performance can decrease significantly in absence of an effective flow control mechanism.
In this paper, the flow control problem is investigated by using a mathematical model in the WiNoC. The aim of this study is showing a correct analysis of cores behaviors with the subject to capacity constraints of links and flow rates. The simulation results of traffic pattern in the WiNoC show that the proposed flow rate control algorithm has been able to control and adjust the flow injection rate of each transmitter with acceptable convergence
Keywords: wireless network on chip, flow control, optimization, gradient projection, congestion control, utility function.
