Cognitive radio (CR) is an enabling technology to allow unlicensed (secondary users to exploit the spectrum allocated to licensed (primary) users in an opportunistic manner. CR is widely considered as a promising technology to deal with the spectrum shortage problem caused by the current in?exible spectrum allocation policy It is capable of sensing its radio environment, and adaptively choosing transmission parameters according to sensing outcomes, which improves cognitive radio system performance and avoids interfering with primary users. CR has been considered in mobile ad hoc networks (MANETs), which enable wireless devices to dynamically establish networks without necessarily using a ?xed infrastructure. CR technology will have signi?cant impacts on the performance in wireless networks, especially in MANETs.

IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 13, NO. 1, FEBRUARY 2005. We consider the problem of wavelength assignment in reconfigurable WDM networks with wavelength converters. We then provide a second algorithm that uses more wavelengths yet requires significantly fewer converters. We also develop a method that allows the wavelength converters to be arbitrarily located at any node in the ring. This gives significant flexibility in the design of t...

IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 13, NO. 1, FEBRUARY 2005. We study fairness of resource allocation in multirate, multicast networks. In multirate networks, different receivers of the same multicast session can receive service at different rates. We develop a mathematical framework to model the maxmin fair allocation of bandwidth with minimum and maximum rate constraints. We present a necessary and sufficient condition for a rate allocat...
