Optical networks have been considered for on-chip communications due to its advantages on bandwidth density, power efficiency and propagation speed over the electrical counterpart. However, the major optical device-micro ring resonator is very sensitive to manufacturing errors and temperature fluctuations, which results in the bandwidth loss or even the failure of optical link. Thus, this paper proposes...
Energy efficient communication is a critical research problem in large-scale multihop wireless networks because of the limited energy supplies from batteries. We investigate in this paper the minimum energy required to fulfill various information delivery goals that correspond to the major communication paradigms in large wireless networks. We characterize the minimum energy requirement in two steps...
Traffic overloading failures are infectious due to the correlations in their occurrence. When a node fails at excessive load, the re-routed traffic may fail other nodes in the network. We present in this paper a mathematical characterization of the resilience of large wireless networks to the traffic overloading failures. We show that as the number of failed nodes increases, the network transits from...
Technology scaling has led to the integration of many cores into a single chip. As a result, on-chip interconnection networks start to play a more and more important role in determining the performance and power of the entire chip. Packet-switched network-on-chip (NoC) has provided a scalable solution to the communications for tiled multi-core processors. However the virtual-channel (VC) buffers in...
Interconnection plays an important role in performance and power of CMP designs using deep sub-micron technology. The network-on-chip (NoCs) has been proposed as a scalable and high-bandwidth fabric for interconnect design. The advent of the 3D technology has provided further opportunity to reduce on-chip communication delay. However, the design of the 3D NoC topologies has important distinctions...
