As mobile cellular networks evolve to carry both traditional voice and new data services, an all-IP based radio access network akin to the Internet is a favorable approach for future radio access n

We demonstrate bidirectional pumped Raman amplification and 1050 km combined WDM/SDM transmission in a 3-spatial-mode few-mode fiber with a 70-km zero net-gain fiber span.

We study Raman Amplification for short-reach systems. The impact of system parameters, including feeder length and discrete connector losses are reported.

We demonstrate distributed Raman amplification compatible with the wavelength plans and rates defined in ITU's specification for TWDM PON.

We demonstrate a multipoint-to-point network architecture for optical metro networks with distributed FEC encoding based on modified staircase codes.

Power control in direct sequence-coded vision multiple access (DS-CDMA) systems and, more recently, power/rate allocation in multirate DS-CDMA based networks is an open and interesting research are

A challenging problem in multi-band multi-cell self-organized wireless systems, such as multi-channel Wi-Fi networks, femto/pico cells in 3G/4G cellular networks, and more recent wireless networks

Robustness of optimization models for network problems in communication networks has been an under-explored topic.

To guarantee the delivery of real-time messages before their deadline, a real-time channel or connection must be established before the transmission of any message belonging to the connection.

Recent years have seen tremendous growth in the deployment of Wireless Local Area Networks (WLANs). An important design issue in such networks is that of distributed scheduling.
