Efficient broadband multi-media data distribution over the Internet using Multicast (2008)
Harish Ramamurthy, Abhay Kar, Rajit Gadh
Receiver heterogeneity severely constrains the performance of multicast transmission schemes. In typical multicast transmission schemes, either the network resources are inefficiently utilized or the...
A Power Optimal Scheduling Algorithm on a Point to Point Wireless Link (2008)
Nitin Salodkar, Abhijeet Bhorkar, Abhay Kar, Vivek S. Borkar
Abstract. In this paper we consider the problem of transmitting packets over a point to point wireless link where the objective is to minimize the average transmitted power subject to a constraint on...
Input-Queued ATM Switch (2008)
1 Introduction Asynchronous Transfer Mode (ATM) has been standardized as the multiplexing and switching technique for Broadband Integrated Services Digital Network (B-ISDN). The ability to provide...

Power Optimal Opportunistic Scheduling (2008)
Abstract — In this paper, we propose a power optimal opportunistic scheduling scheme for a multiuser single hop Time Division Multiple Access (TDMA) system. We formulate the problem of minimizing...
LiME: A Linux based MPLS Emulator (2007)
In this paper, we present the design of a Linux based Emulator for Multiprotocol Label Switching (MPLS) network-LiME. LiME has been designed to emulate real world network toplogies and test actual...

Admission control policies in Code Division Multiple Access(CDMA) systems can be based upon code availability or interference measurements. We have considered voice only cellular CDMA systems with...
Discrete Rate Scheduling for Power Efficient Transmission over (2004)
Abstract — While scheduling transmissions in a wireless communications system can result in significant power savings, a realistic scheduling scheme must take into acvount practical constraints...
Towards an adaptive RED algorithm for achieving delay-loss performance (2003)
Rahul Verma, Aravind Iyer, Abhay Kar
Random Early Detection (RED) [1] is an active queue management strategy that has been deployed extensively in routers. However, its effectiveness has been limited owing to the difficulty in tuning...
1 We consider a traffic flow constrained by a Token Bucket Regulator and analyze it from an infor-mation theoretic point of view. Specifically, we determine the maximum average information (or the...
JOURNAL OF COMMUNICATIONS AND NETWORKS 1 Active Queue Management using Adaptive (2002)
Rahul Verma, Aravind Iyer, Abhay Kar
Random Early Detection (RED) [1] is an active queue management scheme which has been de-ployed extensively to reduce packet loss during congestion. Although RED can improve loss rates, its...
