in this paper we study two access control protocols which have similar two-layer access control architectures for wire-less networks in public places....

In this paper, we present studies of an optical switching (OS) node utilizing a limited number of WCs (wavelength converters) in order to reduce the i...

We introduce a theoretical model of packet pair separation based on a transient solution of the Tak?cs integro-differential equation. We show that in...
