In-band full-duplex (FD) relays are useful for extending coverage areas and increasing overall throughput in wireless networks.
The use of multiple-antenna techniques in downlink wireless networks increases overall throughput by exploiting degrees of freedom in the spatial domain.
In a given area, since power is controlled, the chances of overlapping the sensing ranges of sources and next hop relay nodes or destination node decreases, so it enhances the probability of concurrent transmission and hence an increased overall throughput.
As the cluster size increases, we would ideally see a constant throughput per node, giving a linear increase in overall throughput.
Results show that the increase in overall throughput and availability comes with minor performance degradation.
That is, each traffic class will transmit preferentially packets to SSs which consume smallest number of time slots in order to increase the overall throughput.
In this way, we can take full use of all the available relays in each layer and increase the overall throughput.
Similarly, [20] proposes to halve the CW size (unlike BEB where the CW size is reset to minimum) to increase the overall throughput.
Communication is carried out by three non overlapping channels C1, C2, and C3 in 2.4 GHz frequency band, which has increase the overall throughput of the router up to six times as compared to single channel single radio router.
Through providing additional dimension of space for transmitting signals, multi-antenna systems are believed to be an efficient method to substantially increase the overall throughput of wireless communication [14, 15].
