CURRENT PROJECTS
Supervisor Project Description Year
Prof. Patrick Eugster
Purdue University
 Title: Achieving Global Total Order in Hierarchical Multicast

Using a hierarchical multicast technique for total ordering (pmcast), global total order was achieved in a topic based hierarchical multicast system that divides topics into subtopics for efficient delivery (Data-Aware Multicast).

 2009
Prof. Patrick Eugster
Purdue University
 Title: Efficient Decentralized Orchestration of Hierarchical Topics

Topic discovery scheme for a joining node in a topic based publish/subscribe system that divides topics into subtopics was designed and evaluated. Other system operations for maintaining performance guarantees for a Gossip-based multicast approach were studied and solutions were proposed, simulated and evaluated.

2009
Prof. Ramana Kompella
Purdue University
 Title: Network Host Classification at high speeds

Designed High speed data structures using Bloom Filters for managing information for classifying host behavior in a network using cardinality of a given host.

 2009
Prof. Gopal Pandurangan
Purdue University
 		Title: Leader Election in synchronous environments

Using imperfect oracles for randomized leader election in large scale synchronous systems. The concept of such oracles in synchronous systems was formalized and the guarantees provided by the approach were verified.		 2009
PAST PROJECTS

 		Title: Reliability and Security considerations for a distributed stream processing system

The overlay network of a distributed event based stream processing system was designed and preliminary evaluations were performed. Schemes for high reliability and availability were proposed and implemented.

2008
Prof. Charles Killian
Purdue University
 		Title: Performance Evaluation of Open Source Google BigTable Implementations

Open source implementations of Google BigTable i.e. HBase and Hypertable were deployed over Amazon EC2 infrastructure, their features tested and their performance was evaluated.

 Title: Quad Rotor Unmanned Aerial Vehicle

Designed the Wireless Communication system of the Unmanned Aerial Vehicle. The 3 Km 802.11b wireless link was used to relay the video from the secondary UAV to the primary UAV to the base station. The wireless link was also used to implement the secondary kill switch and retrieval of GPS and other sensor data.

The UAV system was awarded the Most Innovative Design Award at the International Aerial Robotics Competition (IARC) 2006 held at Fort Benning, GA, US. The competition is organized by Association of Unmanned Vehicle Systems International (AUVSI).

 Title: Service Differentiation in 802.11b networks
Network Labs, ECE Dept, Indian Institute of Science

Service differentiation for critical services like VoIP is obtained by classifying packets into one of the four 802.11e access category within WLAN Manager (WM) and scheduling the packets using WFQ scheduler within WM.

Developed a Hybrid Testbed, an integration of physical nodes into the network simulated in Qualnet to evaluate critical parameters on which the QoS of a wireless depends.
