Optimal Control of Switching Topology Networks

Optimal Multistage Switching Networks

from that of Gaussian. It may be noted that this characteristic of pseudo-error detectors was predicted by G ~ o d i n g (~) and may now be regarded as being confirmed.' Scrutiny of Figures 8, 9 and 10 indicates that the achieved stability of the multiplication factor is sufficient to estimate BER from the pseudo-error rate with an accuracy of about a factor of 10 in BER. In addition, the estim...

Optimal topology control for balanced energy consumption in wireless networks

Hosts in wireless networks are usually powered by batteries, thus the lifetime of a network depends on the battery life of each individual host. One major solution to improve energy-efficiency is to minimize the total energy consumption. However, battery energy is a local resource, to save energy at each host and balance the energy consumption among all the hosts in the network appear to be mor...

Topology Switching for Data Center Networks

Emerging data-center network designs seek to provide physical topologies with high bandwidth, large bisection capacities, and many alternative data paths. Yet, existing protocols present a one-size-fits-all approach for forwarding packets. Traditionally, the routing process chooses one “best” route for each end-point pair. While some modern protocols support multiple paths through techniques li...

Optimal Control for Switching Systems

The notion of switching system generalizes the idea of a `diierential equa-tion': a switching system consists of a number of modes (e.g., diierential equations) together with a set of switching rules. Such systems arise in mod-eling thermostats (and other devices involving`hysteresis'), in considering the evolution of a multimodal (variable structure) system for which`feedback control' has been...
