  • Routing Algorithms in. . .  
  • by A. Michail, A. Ephremides, Anastassios Michail, Anthony Ephremides — 1997
  • …In networks with mobile radio nodes in which connectivity varies rapidly with time, it is necessary to develop algorithms for identifying and maintaining paths between communicating pairs of nodes. Motivated by earlier work that accomplishes such a task for datagram packet service, we develop a simi…

  • Combating Performance Degradation in Highly Mobile . . .  
  • by D. Stamatelos, A. Ephremides, Dimitris Stamatelos, Anthony Ephremides — 1997
  • …We examine a simple technique for combating performance degradation by adjusting the rate of the received signal. Using adaptive demodulation, the receiver can respond to deteriorating conditions trading BER for rate and vice-versa, without involving the transmitter. This way the receiver has more c…

  • Communication Protocols for Secure Distributed Computation of Binary Functions  
  • by Eytan Modiano, Anthony Ephremides — 2000
  • …this paper we develop communication protocols which allow for such computation to take place while maintaining the value of the function secret to an eavesdropper. Of interest is the communication complexity of such protocols. We begin by considering two processors and two channels, one secret and o…

  • Dynamic Scheduling for Minimum Delay in Tandem and Parallel Constrained Queueing Models  
  • by Leandros Tassiulas, Anthony Ephremides — 1994
  • …this paper. The servers are dependent in the sense that they can not provide service all of them simultaneously. A collection of sets of servers is prespecified and the set of servers that provide service at each time instant is constrained to belong to that collection. We call these queueing system…

  • Joint Routing and Scheduling Metrics for Ad Hoc Wireless Networks  
  • by Tolga Girici, Anthony Ephremides — 2002 — in Proc. of the 36th Asilomar Conference on Signals, Systems and Computers, 2002
  • …In this paper we address the problems of routing and scheduling in resource-limited ad hoc wireless networks supporting connectionless traffic. Motivated by the novel challenges and trade-offs introduced by ad hoc wireless networks, we propose link metric-based distributed routing and scheduling alg…

  • Energy-efficient power control in wireless queueing networks  
  • by Tolga Girici, Anthony Ephremides — 2004 — in Proc. 37th Annual Allerton Conf. Communication, Control and Computing
  • …In this paper we consider the problem of power control of packet data transmission in a two user multiple access system, with joint consideration of average energy per packet and delay per packet. The problem we consider is an interacting queue problem, where the packets arrive randomly to the buffe…

  • Asymptotic Analysis of an OFDMA Scheme with Random Packet Arrivals  
  • by Tolga Girici, Anthony Ephremides
  • …Abstract — In this work we perform a queueing analysis of an OFDMA-based and channel-aware resource allocation scheme. We estimate the service characteristics of the queues using extreme value theory and estimate the tail probability of queue size distribution using generating function approach. Bas…

  • Information Theory and Communication Networks: An Unconsummated Union  
  • by Anthony Ephremides, Bruce Hajek — 1998 — IEEE Trans. Inform. Theory
  • …Information theory has not yet had a direct impact on networking, although there are similarities in concepts and methodologies that have consistently attracted the attention of researchers from both fields. In this paper, we review several topics that are related to communication networks and that …

  • Review of the VSAT ACTS Experiments at the Center for . . .  
  • by D. Friedman, S. Gupta, C. Zhang, A. Ephremides, Daniel Friedman, Sonjai Gupta, Chuanguo Zhang, Anthony Ephremides — 1996
  • …This paper describes experiments conducted over ACTS and the associated T1 VSAT terminal. The experiments were motivated by the commercial potential of low-cost receive-only satellite terminals that can operate in a hybrid network environment, and by the desire to demonstrate frame relay technology …
