— This paper presents an architecture for adaptive cognitive radio networks based on the concept of a “global control plane”. The proposed control architecture uses a predete...
Abstract— In this paper, we have proposed an analytical model for optical networks with full wavelength conversion at the nodes. We have derived an analytical expression to compu...
—We propose a new teletraffic model for the calculation of link occupancy distribution and determine the call blocking probabilities and link utilization in a single-link multi-r...

— In this paper, we study the link layer scheduling problem in wireless ad hoc networks. In such a network, the communication links compete for the scarce and time-varying wirele...
—Direct sequence spread spectrum (DSSS) technique has been widely used in both military communications and commercial communications. On the other hand, it is a challenge to both...
