Several researchers are investigating using wireless interconnects in Networks-on-Chips (NoCs) as an alternative to traditional wired interconnects. Recent works have proposed a wireless NoC using ultra-wideband CMOS technology, a wireless MAC protocol for concurrent channel use, and a wireless NoC with unequal RF transceivers to improve mesh topology performance. Other research has designed on-chip wireless networks using sub-THz frequencies with small antennas and transceivers, and a wireless NoC using CNT antennas and a small-world topology in the THz range.

Survey for designing nocs with wireless
1. Several researchers are investigating the possibility of designing NoCs with wireless
interconnects. Recently, the design of a wireless NoC based on CMOS Ultra Wideband
(UWB) technology was proposed Zhao et al. [2008]. In Zhao et al. [2011] a wireless
Media Access Control (MAC) protocol based on time-multiplexing of ultra-short pulses
from the UWBtransceivers was proposed to enable concurrent use of the wireless channels.
A wireless NoC with unequal RF transceivers is proposed in Zhao et al. [2012]
to improve the performance in a conventional mesh topology overlaid with wireless interconnects.
In Lee et al. [2009] the design of on-chip wireless communication network
with miniature antennas and simple transceivers that operate at the sub-THz range
of 100500 GHz has been proposed. Design of a wireless NoC using the small-world
topology using carbon nanotube (CNT) antennas operating in the THz frequency range
is elaborated in Ganguly et al. [2011a].
