Receiver based distributed relay selection scheme for 60-GHz networks

Networks based on 60-GHz promise data rates in gigabits and show least tolerance towards signal blockage. In addition to severe propagation loss, signal blockage may result in an attenuation upto 40dB. Distributed relay selection scheme is proposed in this paper to cater for signal attenuation. By maintaining a table containing details about interference measurements and neighboring devices, a receiver device determines an optimal relay for its active transmission. Furthermore, outage probability analysis is provided and is utilized to compare our proposed scheme with direct transmission and fixed node relay scheme. Simulation results show that our proposed scheme significantly improves outage probability and system throughput.
