Rate Constrained Random Access over a Fading Channel (2009)

Salodkar, Nitin, Karandikar, Abhay

In this paper, we consider uplink transmissions involving multiple users communicating with a base station over a fading channel. We assume that the base station does not coordinate the transmissions...

A Stable On-line Algorithm for Energy Efficient Multi-user Scheduling (2009)

Salodkar, Nitin, Karandikar, Abhay, Borkar, V. S.

In this paper, we consider the problem of energy efficient uplink scheduling with delay constraint for a multi-user wireless system. We address this problem within the framework of constrained Markov...

Delay Constrained Point to Multi-Point Scheduling in Wireless Fading Channels (2008)

Nitin Salodkar, Powai Mumbai, Abhay Karandikar

Abstract — In this paper we consider the problem of designing a centralized scheduler on the downlink for satisfying average delay constraints of users having time varying wireless channels. We...

Some results on communicating the sum of sources over a network (2008)

Rai, Brijesh Kumar, Dey, Bikash Kumar, Karandikar, Abhay

We consider the problem of communicating the sum of $m$ sources to $n$ terminals in a directed acyclic network. Recently, it was shown that for a network of unit capacity links with either $m=2$ or...

Optimal Packet Scheduling Algorithms for Token-Bucket Based Rate Control (2008)

Mehta, Neerav Bipin, Karandikar, Abhay

In this paper, we consider a scenario in which the source has been offered QoS guarantees subject to token-bucket regulation. The rate of the source should be controlled such that it conforms to the...

Link Scheduling in STDMA Wireless Networks: A Line Graph Approach (2007)

Kumar, N. Praneeth, Gore, Ashutosh Deepak, Karandikar, Abhay

We consider point to point link scheduling in Spatial Time Division Multiple Access (STDMA) wireless networks under the physical interference model. We propose a novel link scheduling algorithm based...

Asymptotic Capacity of Wireless Ad Hoc Networks with Realistic Links under a Honey Comb Topology (2007)

Asnani, Himanshu, Karandikar, Abhay

We consider the effects of Rayleigh fading and lognormal shadowing in the physical interference model for all the successful transmissions of traffic across the network. New bounds are derived for...

Power Efficient Scheduling under Delay Constraints over Multi-user Wireless Channels (2007)

Salodkar, Nitin, Karandikar, Abhay, Borkar, Vivek S.

In this paper, we consider the problem of power efficient uplink scheduling in a Time Division Multiple Access (TDMA) system over a fading wireless channel. The objective is to minimize the power...

On High Spatial Reuse Link Scheduling in STDMA Wireless Ad Hoc Networks (2007)

Gore, Ashutosh Deepak, Jagabathula, Srikanth, Karandikar, Abhay

Graph-based algorithms for point-to-point link scheduling in Spatial reuse Time Division Multiple Access (STDMA) wireless ad hoc networks often result in a significant number of transmissions having...

Entropy-optimal Generalized Token Bucket Regulator (2006)

Gore, Ashutosh Deepak, Karandikar, Abhay

We derive the maximum entropy of a flow (information utility) which conforms to traffic constraints imposed by a generalized token bucket regulator, by taking into account the covert information...

Eisodus Networks Private Limited (2006)

Abhay Karandikar, Zainul Charbiwala

In this article, we focus on the challenges and opportunities for broadband access deployment in India. We present an overview of the broadband scenario in India and the existing network...
