IP over optical networks controlled by the GMPLS control plane have become the common infrastructure for a variety of services, such as triple play and grid applications. The traff...
In this paper, we introduce two protocols - a routing and a broadcasting protocol - for ad-hoc networks which are based on a new paradigm enabled by the broadcast property of the w...
This paper presents several results on dynamic OFDMA systems. It addresses especially the algorithmic complexity involved with several resource allocation approaches, sub-optimal h...
