“…In [17], authors have proposed a multi-channel WiNoC platform and in [18], a communication channel in the Ka band is proposed to improve the on-chip communication of many-core chips. A parameterizable wireless channel model is proposed in [19] to evaluate the losses in WiNoC and to simulate the platform better. In [20], authors have shown the impact of a semi-realistic multipath wireless channel over conventional WiNoC modulation scheme and have proposed a digital transceiver architecture.…”

IntroductionA Wireless Network-on-Chip (WiNoC) offers a promising solution to reduce broadcast and long distance communication bottlenecks of conventional architectures by augmenting them with single hop wireless links. In this paper, we discuss new security vulnerabilities and countermeasures to protect against them in a WiNoC based system. In particular, we describe Malicious Threshold Configuration (MTC) Attack, Disruptive Token Passing (DTP) Attack, Data Stealing by Broadcast (DSB) Attack and Hybrid Attack against the WiNoC. Our proposed countermeasure against MTC-OU (over-utilization) attack i.e., Source Destination checking mechanism decreases wireless hub utilization by 49% and network latency by many orders of magnitude compared to without countermeasure, causing system performance improvement.Another proposed countermeasure against DTP attacks i.e., detour mechanism improves the network throughout by 1.21x and 23x under DTP-AHT and DTP-DOS attacks respectively.

“…Few prior works have introduced some interesting channel features that could have been considered for WiNoC simulations. For instance, a two-ray signal propagation and molecular absorption attenuation (MAA) were introduced in [13] and [14], respectively. Further, a proof-of-concept study was performed in [15] using isotropic integrated dipole antennas in ka band (26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40).…”

“…The WiNoC channel must be modeled considering the parasitic phenomena introduced by the physical structure and electrical properties of all the components inside the chip and by the chip package [14]. Therefore, the design of an accurate channel model for WiNoC applications is important but it is also a complex task.…”

Wireless Network-on-Chip (WiNoC) is a viable solution to overcome critical bottlenecks in on-chip communication backbone. However, standard WiNoC approaches are vulnerable to multi-path interference introduced by on-chip physical structures. To overcome such parasitic phenomenon, this paper presents an adaptive digital transceiver, which enhances communication reliability under different wireless channel configurations. Based on a semi-realistic wireless channel model, we investigate the impact of using some channel correction techniques. Experimental results show that our approach significantly improves Bit Error Rate (BER) under different wireless channel configurations. Moreover, our adaptive transceiver allows for wireless communication links to be established in conditions where this would not be possible for standard transceiver architectures. The proposed architecture, designed using a 28nm FDSOI technology, consumes only 3.27 mW for a data rate of 10 Gbit/s and has a very small area footprint.

“…However, the conventional metal based interconnections are insufficient to satisfy the needs of both low latency and high performance as the number of cores increases. Alternative fabrics and architectures, such as photonic NoC [12], nanophotonic NoC [13], three-dimensional (3D) NoC [14], Wireless NoC (WiNoC) [15][16][17][18][19], and hybrid WiNoC [20][21][22][23], have been then investigated.…”

One of the main challenges towards the growing computation-intensive applications with scalable bandwidth requirement is the deployment of a dense number of on-chip cores within a chip package. To this end, this paper investigates the Wireless Networkon-Chip (WiNoC), which is enabled by graphene-based nanoantennas (GNAs) in Terahertz frequency band. We first develop a channel model between the GNAs taking into account the practical issues of the propagation medium, such as transmission frequency, operating temperature, ambient pressure, and distance between the GNAs. In the Terahertz band, not only dielectric propagation loss but also molecular absorption attenuation (MAA) caused by various molecules and their isotopologues within the chip package constitutes the signal transmission loss. We further propose an optimal power allocation to achieve the channel capacity. The proposed channel model shows that the MAA significantly degrades the performance at certain frequency ranges compared to the conventional channel model, even when the GNAs are very closely located. More specifically, at transmission frequency of 1 THz, the channel capacity of the proposed model is shown to be much lower than that of the conventional model over the whole range of temperature and ambient pressure of up to 26.8% and 25%, respectively.
