DAC

A game theoretic model and a distributed admission control scheme for quality of service routing

In this paper, we present an innovative distributed quality of service routing scheme suitable to operate in networks of general topology implementing a Diff-Serv service model for QoS support. The proposed scheme is based on a game theoretic non-cooperative model which exploits, on the one hand, the topological information distributed within the network by the current (non-QoS) link-state and distance-vector routing protocols and, on the other hand, the QoS information locally available at the node where the forwarding process takes place.

Mathematical Model for the Output Signal’s Energy of an Ideal DAC in the Presence of Clock Jitter

A mathematical model for the output signal’s energy of a multidimensional ideal DAC is presented considering sampling clock jitter. More specifically, a new model is formulated to prove one-sided energy inequality for the output signal, for which the base time is affected by the jitter. Moreover, a family of annihilate operators is defined and applied to the ideal (one-dimensional) DAC model to estimate the output signal energy.
