completed my in the Computer Science Department, Rutgers
University, working as a Graduate Assistant in the research group of DATAMAN
Lab, CS Dept. Currently I am employed as a Computer Scientist in GE
Global Research, Advanced Communication Systems Lab, in Computing and
Decision Sciences Department.. Please follow the links below for more
details. PhD Thesis: Algorithms for Resource
Utilization in Sensor Networks Links to Research Projects In Dataman Lab. Ad Hoc and Sensor Networks Management Information Assurance in Sensor Networks PROJECTS AND PUBLICATIONSProjects
at Telcordia Applied Research: Network
Management with Machine Learning Techniques: Autonomous network management for tactical, ad-hoc
using machine-learning techniques. We use Reinforcement Learning, Parameter
Estimation and local regression used to solve the optimal server allocation
problem in mobile ad-hoc environments.
Power Conservation
in Ad-Hoc Networks: We employ
optimization techniques (using node scheduling and transmit power control)
for minimizing power consumption in multi-hop wireless networks. Mobile Robots
Deployment: Design of distributed
algorithms for ad-hoc mobile robot deployment in indoor environments. Using
potential field and cellular automata techniques. Protocol
Enhancements Using Directional Networking Capabilities: We explore the challenges and enhancements using
directional antennas for MAC, Routing, Multicast etc. protocols in Wireless
Networks. Quality of
Service for Ad-Hoc Networks:
Research on admission control, quality of service routing and resource
management in Mobile Ad-Hoc Networks. Working on Wireless Bandwidth
Estimation (from SNR) and Throughput analysis of 802.11 protocols. Analyzing
Many-to-One Traffic Behavior: We
develop queuing theoretic models to analyze the effect of Many-to-One traffic
(frequently observed in sensor networks) and show the non-trivial and non
trivial nature of network capacity, lifetime, bottleneck formation and buffer
overflow problem in such networks. Topology Control
and Inference in Sensor and Ad Hoc Networks: We analyze the
two different approaches of topology control: Node Scheduling and
Transmission Power control. Using Probabilistic methods, we analyze the
performance of these approaches for random unit disk graphs and propose
distributed, message optimal and constant approximation bound algorithms for
topology control. sNMP (Sensor
Network Management Protocols): Definition
of network management issues, management functions and protocols, models to
represent sensor network state and efficient ways of extracting sensor
network state. We explore multi-resolution state retrieval and management of
sensor networks, sensor networks and adaptive protocols (learning and
modeling based) for sNMP. Information
Assurance (QoS) in Sensor Networks: Define metrics for Sensor Quality of Service, to
support information awareness and assurance in multi-hop wireless networks.
We propose three different algorithms to support information assurance in
reliability for sensor networks. Natural Language
Processing: Automated Spoken
Dialogue System for Public Transport Information: Design architecture for an automated Spoken Dialogue
System for public transport and travel planning. The Dialogue Manager is
based on Shared Plan Theory of Discourse, and Belief, Desire and Intentions
model for Speech Acts. Projects in Undergraduate Studies: Image
Compression: Image Compression
using Wavelet Transform and Multi-resolution Decomposition. B.Tech Project,
(1999). Implemented an Efficient Image Compression technique using Debauche
Wavelets and applying multi-resolution decomposition. Computer Vision: Tracking of Moving Objects from a Sequence of
Images to Estimate Motion and 3D Structure of Objects, IIT Delhi
(1998-99). Involved feature extraction finding correspondences between a pair
of images. Developed a new matching algorithm for a sequence of images of
moving objects. Robotics: Design and implementation of a hexagonal six-legged
robot. Was involved in the robot navigation algorithm and motion (alternate
tripod gait pattern). Also implemented a 3D graphics simulation of the Robot
navigation system and motion parameters for algorithm design and analyses. SELECTED PUBLICATIONS
