Research On DoS Defense Mechanisms And Multichannel Architecture In WiNoC

Wireless Networks-on-Chip(Wi No Cs)have been regarded as the promising alternative to conventional wired Networks-on-Chip(No Cs)to deal with their inherent multi-hop issues in terms of latency and power.Millimeter-wave(mm-Wave)technology has been widely adopted in recent Wi No C designs since it is fully compatible with current CMOS process and features unique advantages in power,data rate and transmission range when compared with other RF technologies.This thesis explores Do S defense mechanisms and multi-channel architecture in mm-Wave Wi No C.The main work of the thesis is as follows:(1)This thesis proposes an efficient and light-weighted Do S defense mechanism.Specifically,the negative impact of Do S attacks on the performance of Wi No Cs will be minimized by strictly restricting channel access of WIs through enhanced MAC mechanisms.Compared with the state-of-the-art Do S defense mechanisms,our scheme covers more Do S attack scenarios and achieves more efficient and accurate Do S detection at significantly reduced power/area cost providing system with better security.(2)In this thesis,a mm-Wave multichannel wireless transceiver is integrated into the Wi No C,based on which,a high-performance millimeter-wave multichannel Wi No C architecture is elaborated including the designs of topology,routing and MAC mechanisms.Besides,to relieve the congestion in hubs,a congestion-aware adaptive channel selection(CAACS)mechanism is also proposed.Simulation results show that such an architecture increases the saturated throughput by 16%?98% and by introducing the CAACS mechanism,the saturated throughput can be further improved by up to 17%.The average packet delay is also significantly reduced while the area and power overhead are acceptable.
