Major Projects and Seminars

• M.Tech Project : Design & Evaluation of a Distributed TDMA MAC Protocol for 802.11 Mesh Networks (Master’s , Guide: Prof. Bhaskaran Raman) [Autumn ’10 – Spring ’11] o Goal : To design a distributed TDMA MAC protocol for 802.11 mesh networks that can support dynamic traffic and provide deterministic fairness among the end-to-end flows while delivering a high throughput o Major Challenges : Sustaining a stable throughput across multiple hops in the face of varying & competing traffic patterns and maintaining per-flow fairness while taking into account the complex dynamics of TCP o Performed an NS2 simulation of the designed protocol, analyzed its behaviour (at macro and micro levels) and compared its performance with that of IEEE 802.11 DCF under various scenarios and topologies o The protocol shows good performance in multi-hop scenarios even in the presence of significant channel errors , and delivers a steady throughput and a fine-grained fairness among multiple competing TCP flows

• M.Tech Seminar : Analysis of MAC and Time Sync Interaction (Guide: Prof. Bhaskaran Raman) [Spring ’10] o Performed a literature survey on MAC protocols and Time Sync protocols for Wireless Sensor Networks o Compared some of the recent developments in the two classes of protocols on various practical aspects o Pointed out several types of interaction between Time Synchronization protocols and the underlying MAC protocols, revealing their inter-dependencies and highlighting the need for a unified approach

• B.Tech Project : Network Manager for HTTP Proxy Server (Guide: Prof. Swagata Paul) [2008 – 09] o Goal : To build a Network Management tool from scratch to run on HTTP Proxy Servers o Major Challenge : To strictly enforce user quotas (kill ongoing transfers whenever quota is exceeded) o Designed, implemented and deployed a Network Manager to run on a Squid-based HTTP Proxy Server and track sessions, maintain and enforce user quotas and log all internet activities per user o The system is presently operational at Techno India, Kolkata

Major Course Projects

• Dom0 CPU chargeback for network Tx operations in Xen (Guided by Prof. P. Kulkarni) [ Autumn ’10 ] Modified the kernel virtual network driver (netback ) at the Xen host domain to log the overheads required to process each packet coming from different guest domains, and modified the Xen resource monitoring tool (xentop ) to charge these processing overheads to the corresponding guest domains rather than to the host domain

• Autonomous Obstacle-Mapping Robot (Guided by Prof. P. C. Pandey & Prof. D. K. Sharma) [ Spring ’10 ] Built an Autonomous Robot from scratch (based on 8051 microcontroller ), which can fully explore a bounded room full of obstacles, and on completion, transfer the floor map to a PC using RS-232 serial interface

• Simple BitTorrent prototype (Guided by Prof. Kameswari Chebrolu) [Autumn ’09] Implemented a simple BitTorrent prototype peer-to-peer application on Linux and extensively tested it on LAN

• Minimum Cost Sink Routing Protocol on Sensor Motes (Guided by Prof. Bhaskaran Raman) [ Spring ’10 ] Designed and implemented a Single-Destination Minimum Cost Routing Protocol on TinyOS , and evaluated it on TelosB Sensor Motes (using IEEE 802.15.4 radios) for various topologies and scenarios

• Materialized View Definition and Maintenance for PostgreSQL (Guided by Prof. N. L. Sarda) [Autumn ’09] Extended PostgreSQL Database to support Materialized View Definition and Maintenance for simple tables

• Automatic Online Program Evaluation and Grading System (Guided by Prof. G. Sivakumar) [Autumn ’09] Designed & developed a system to be used as an automatic code evaluator in online programming contests (deployed and tested during EDGE ’10 , the second largest tech-fest in West Bengal, organized by Techno India)

Other Course Projects and Seminars

• Simulated and evaluated Snoop TCP using the NS2 simulator (Guide: Prof. Anirudha Sahoo) • Simulated OLSR using the NS3 simulator & fixed a bug in NS3 code for OLSR (Guide: Prof. Anirudha Sahoo) • Implemented K-NN Queries on an R-Tree based index of spatial data (Guide: Prof. N. L. Sarda) • Implemented and evaluated PAX Storage Model on the ToyDB system (Guide: Prof. N. L. Sarda) • Developed a multiplayer game Dots & Boxes using Java (Guide: Prof. G. Sivakumar) • Presented a Seminar on Adaptive Neuro-Evolutionary Opponents in Pacman (Guide: Prof. P. Bhattacharya)
