“…An important feature of WiNoCs is low power consumption. In particular, in [23], it is shown how the energy efficiency of a WiNoC can be achieved by techniques that power-off wireless routers when they are not used in the wireless transmission [23]. Another significant aspect of wireless links is high bandwidth availability.…”

The Network-on-Chip (NoC) paradigm emerged as a viable solution to provide an efficient and scalable communication backbone for next-generation Multiprocessor Systems-on-Chip. As the number of integrated cores keeps growing, alternatives to the traditional multi-hop wired NoCs, such as wireless Networks-on-Chip (WiNoCs), have been proposed to provide long-range communications in a single hop. In this work, we propose and analyze the integration of the Delta Multistage Interconnection Network (MINs) as a backbone for wireless-enabled NoCs. After extending the well-known Noxim platform to implement a cycle-accurate model of a wireless Delta MIN, we perform a comprehensive set of SystemC simulations to analyze how wireless-augmented Delta MINs can potentially lead to an improvement in both average delay and saturation. Further, we compare the results obtained with traditional mesh-based topologies, reporting energy profiles that show an overall energy cost reduced on both wired/wireless scenarios.

“…Few papers have explored random access or on-demand solutions, which can provide low latency when the load is moderate and adapt to changes in traffic. Dai et al propose the use of slotted Carrier Sense Multiple Access (CSMA) with optimal persistence calculated a priori [6]. Also, Mansoor et al present an adaptive scheme that switches between CSMA and token passing depending on the level of contention [14].…”

“…In this paper, we focus on the MAC issue and propose BRS-MAC, a protocol specifically suited to the broadcastoriented WNoCs. We observed that existing works on WNoC either rely on channelization or token passing schemes that do not scale well [7,9], or map protocols to the on-chip scenario without considering broadcast patterns [6,14]. Instead, our work takes advantage of the unique application context to propose a scalable and reliable solution, as well as to develop highly accurate performance models.…”

The Wireless Network-on-Chip (WNoC) paradigm holds considerable promise for the implementation of fast and efficient on-chip networks in manycore chips. Among other advantages, wireless communications provide natural broadcast support, a highly desirable feature in manycore architectures yet difficult to achieve with current interconnects. As technology advancements allow the integration of more wireless interfaces within the same chip, a critical aspect is how to efficiently share the wireless medium while reliably carrying broadcast traffic. This paper introduces the {Broadcast, Reliability, Sensing} protocol (BRS-MAC), which exploits the particularities of the WNoC context to meet its stringent requirements. BRS-MAC is flexible and employs a collision detection and notification scheme that scales with the number of receivers, making it compatible with broadcast communications. The proposed protocol is modeled and evaluated, showing a clear latency advantage with respect to wired on-chip networks and WNoCs with token passing.

“…WiNoC has the advantage of reducing latency and improving throughput compared to wired NoC as it requires one hop to transmit data from one WR to another WR. By considering the advantages of each of the approaches, it is a good way to combine both approaches to form a hybrid wired-wireless NoC in Chip Multiprocessor (CMP) so as to optimise the latency, throughput, and energy efficiency [5,6]. The idea of hybrid wired-wireless designs is to utilise the wired links for short-distance communication within a small group of nodes whereas wireless links can be utilised for long-range communication to reduce the latency and improve the power efficiency.…”

Three-level hierarchical hybrid wired-wireless Network-on-Chip (NoC) architectures are proposed in this article. Various hybrid wired-wireless configurations have been proposed and examined under various traffic patterns at low, medium, and high traffic loads. In the proposed three-level hierarchy, the bottom and top levels are concerned with subnet topology and wireless hub topology, respectively. The present research introduces a middle level that investigates the number of nodes that will be connected to a subnet's wireless hub. Mesh and fully connected wireless topologies have been chosen for the bottom and top levels of the hierarchy, respectively. Different hybrid wired-wireless configurations have been developed and studied by varying the number of subnets and the number of nodes to be attached to the subnet at the middle level. The objective of investigating the middle level is to reduce the number of subnets and, consequently, the number of wireless nodes in large network architectures without compromising performance.
