B-HIVE: A CELL PLANNING TOOL FOR URBAN WIRELESS NETWORKS (2009)

Harish Ramamurthy, Abhay Kar

The paper presents a demand-based engineering method for designing urban wireless networks. We present an integrated approach to include the effects of both tele-traffic and radio signal coverage for...

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)

Arvind Santhanam, Abhay Kar

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...

Performance Modeling of Statistical Multiplexer with Composite Traffic Input by CIPP/M/1 Queue (2008)

R. Manivasakan, U. B. Desai, Abhay Kar

or self-similar models [3]) or the correlation introduced by the modulating Markov chain as in Markov modulated models [5].

Power Optimal Opportunistic Scheduling (2008)

Abhijeet Bhorkar, Abhay Kar

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)

Abhijit Gadgil, Abhay Kar

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...

Performance Analysis of Discrete Time Bulk Queues with Restricted Departure Sizes in Power Efficient Scheduling (2006)

Premal Shah, Abhay Kar

We consider a class of discrete time bulk-service queues with buffer of infinite size where requests can be serviced in batches of given fixed sizes only. We provide techniques to obtain the steady...

Power Optimal Opportunistic Scheduling in Fading Wireless Channel (2006)

Abhijeet Bhorkar, Abhay Kar, Vivek S. Borkar

1 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 average...

Power Optimal Opportunistic Scheduling in Fading Wireless Channel (2006)

Abhijeet Bhorkar, Abhay Kar, Vivek S. Borkar

1 In this paper, we propose a power optimal opportunistic scheduling scheme for a multiuser sin-gle hop Time Division Multiple Access (TDMA) system. We formulate the problem of minimizing average...

Performance Analysis of Cellular CDMA with Handoff under Signal-to-Interference Ratio based Admission Control (2005)

Dhruva Garg, Nitesh Dixit, Abhay Kar

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)

Premal Shah, Abhay Kar

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...

Pricing Index Terms (2003)

Premal Shah, Abhay Kar

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...
