For automatically switched dynamic wavelength paths meeting traffic demands of metro/core networks, precise determination of physical impairments over such paths and appropriate configuration of their compensation capabilities are required. This paper discusses control protocol for impairment measurement and compensation configuration for wavelength paths based on the IETF's WSON standardization efforts.
This paper analyzes distributed asynchronous power and rate control for wireless ad hoc networks. Importantly, all network transmitters are considered to be independent of any management infrastructure and to have the freedom to choose their own arbitrary control rules, using as input only information on local interference and achieved carrier signal-to-interference ratio (CIR). Such an approach respects...
The joint effect of power control, access control, and multi-hop transmission on spectral efficiency of a cognitive radio system is evaluated, focusing on the trade-off between the performance of a high priority system and that of a low priority system. So as to avoid interference to the high priority system, the low priority system is assumed to reduce transmit power through power control or stop...
In cognitive radio, reliable detection of the primary system is crucial for the secondary system. However, there is an uncertainty in the received power level due to shadowing. The cooperative sensing where the stations in the secondary system share their sensing information can improve the detection accuracy of the primary system. In this paper, a new secondary system for reducing interference to...
This paper presents a novel game-theoretic framework for distributed adaptive power control in wireless ad-hoc networks. It first shows the equivalency of two recent approaches to this noncooperative field - the QoS utility maximization approach and the best-response approach. We then choose to follow the analytically more intuitive best-response approach and analyze in an abstract way general conditions...
