  • Some dynamic resource allocation problems in wireless networks  
  • by Randall Berry — 2001 — Proc. of SPIE ITcom
  • …We consider dynamic resource allocation problems that arise in wireless networking. Specifically transmission scheduling problems are studied in cases where a user can dynamically allocate communication resources such as transmission rate and power based on current channel knowledge as well as traff…

  • Power and Delay Optimal Transmission Scheduling: Small Delay Asymptotics  
  • by Randall Berry — 2003 — IEEE ISIT
  • …For wireless data traffic, energy efficiency can be improved by adapting the transmission power and rate over time based on the offered traffic as well as any channel state information. In this context, a variety of transmission scheduling approaches have been studied including [1, 2, 3]. These appr…

  • Distributed approaches for exploiting multiuser diversity in wireless networks  
  • by Xiangping Qin, Randall Berry — 2006 — IEEE Transactions on Information Theory
  • …In wireless fading channels, multiuser diversity can be exploited by scheduling users so that they transmit when their channel conditions are favorable. This leads to a sum throughput that increases with the number of users and, in certain cases, achieves capacity. However, such scheduling requires …

  • Buffer Control for Communication over Fading Channels  
  • by Randall Berry, Robert Gallager — 2000 — in Proc. 2000 IEEE International Symposium on Info. Th
  • …We consider a user communicating over a flat fading channel. The user wishes to reliably communicate bursty data over this channel while minimizing both the average power and the average delay incurred. We formulate a buffer control problem which illustrates the trade-off between these quantities. T…

  • A Distributed Splitting Algorithm for Exploiting Multiuser Diversity  
  • by Xiangping Qin, Randall Berry — 2003
  • …this paper, we focus on decentralized approaches for exploiting multiuser diversity, where each user only has knowledge of its own fading level, but no knowledge of the fading levels of the other users in the cell. This is similar to decentralized power control problems, as in [2]…

  • The Role of Switching in Reducing Network Port Counts  
  • by Eytan Modiano, Randall Berry — 2001 — 2001 Allerton Conference on Communication, Control, and Computing
  • …We consider the role of switching in minimizing the number of electronic ports (e.g., SONET ADMs) in an optical network that carries sub-wavelength traffic. Providing nodes with the ability to switch traffic between wavelengths, such as through the use of SONET cross-connects, can reduce the require…

  • Downlink resource allocation and pricing for wireless networks  
  • by Peter Marbach, Randall Berry — 2002 — IEEE INFOCOM
  • …Abstract---This paper considers resource allocation and pricing for the downlink of a wireless network. We describe a model that applies to either a time-slotted system (e.g. Qualcomm's HDR proposal) or a CDMA system; the main feature of this model is that the channel quality varies across the users…
