Performance Improvement of TCP with Delayed (2008)
Acks In Ieee, Arzad A. Kherani
We use a Markov renewal reward approach to analyse the throughput achieved by a TCP connection spanning a multi-hop wireless network that uses the IEEE 802.11 MAC protocol. The significance of the...
Capacity of Markov Channels: A Stochastic Control Approach (2008)
Vivek S. Borkar, Arzad A. Kherani, Vinod Sharma
The problem of maximizing the input-output mutual information rate for a Markov channel is cast as a problem of controlling a partially observed controlled Markov chain on a suitable state space with...
Optimal Random Access in Networks with Two-Way Traffic (2008)
Eitan Altman, Vivek S. Borkar, Arzad A. Kherani, Eitan Altman Ý
We consider a random access network in which the nodes need to optimize their channel access rates. The nodes are assumed to be rational and interested in their performance seen as a transmitter as...
Performance Modeling and Analysis of TCP over Wireless Ad Hoc Networks with IEEE 802.11 MAC (2008)

We consider the problem of modeling TCP over wireless ad hoc network using the IEEE 802.11 protocol. By identifying suitable regeneration instants, we are able to apply the standard technique of...
1 Performance Analysis of TCP with Nonpersistent Sessions (2007)
Arzad A. Kherani, Anurag Kumar
Abstract---Most analytical models of TCP assume that the sessions have an infinite amount of data to transmit. In practice, it is well known that sessions arrive, transfer a finite amount of data and...

Non-cooperative Forwarding in Ad-hoc Networks (2004)
Altman, Eitan, Kherani, Arzad A., Michiardi, Pietro, Molva, Refik
A wireless Ad-hoc network is expected to be made up of energy aware entities (nodes) interested in their own perceived performance. An important problem in such a scenario is to provide incentives...
Performance Analysis and Stochastic Stability of Congestion Control Protocols (2004)
Altman, E., Avrachenkov, Konstantin, Kherani, Arzad A., Prabhu, Balakrishna
We study an Adaptive Window Protocol (AWP) with a general increase and decrease profiles in the presence of window dependent random losses. We derive a steady-state Kolmogorov equation and then...
