My perspective has been not only to implement theoretical innovations but also to broaden my channels of knowledge & fill the repository of practical and pragmatic experiences. Following projects have confirmed my belief that one gets to learn more through experiments than just learning theoretical concepts:
Object Counter (FE-2004) : To count the number of objects on a large scale in industries like Soap Manufacturing plant. We employed IC 7490(Decade Counter), IC 7447 (BCD-7 Segment Decoder) & LDR (Light Dependant Resistor). Find the documentation here
Co-authored with : Santosh Patil
File Splitter (SE-2005, Language-C) : To split a larger file (of any kind) into smaller pieces & merge it back without losing any contents. We (3 team members) also provided options for custom split & quick split to fulfill user requirements. Find the presentation here
Co-authored with : Santosh Patil, Ashish Deshpande
Mail & Informatio Management (TE-2006, Language-VB+SQL) : To keep a database of various acquaintances with people in our day to day life by different means such as phone, mail, letter, fax, etc., extremely user friendly software primarily created from an organizations public-relations prospective.
Co-authored with : Balaji, Ashish Deshpande, Amrut Bang
Multiple Identity Manager (TE-2006, Language-HTML+ASP) : A web-based application (account holder) to store the different usernames and passwords of a particular user for various bank accounts, e-mail accounts, etc.
Co-authored with : Balaji, Ashish Deshpande, Amrut Bang
Gaia-VoIP Traffic Generator & Analyser (BE-2007, Language-C+Qt) : A standalone application simulating multiple clients on a single machine generating real time intelligent traffic emulating actual networking conditions to test the performance of VoIP server & measure traffic statistics. The project deals with client simulation & is a massively multithreaded application. Achievements : - Presented at Techkriti-07 at IITK, Presented at Tryst-07 at IITD, 2nd Prize at Nation level technical event 'Impetus & Concepts' at PICT,PUNE in Networking & Networking Applications category.

MTech course projects
Network Security Group Blind Digital Signatures with Revocable Anonymity : A group blind signature allows individual members of a possibly large group to digitally sign a message on behalf of the entire group in cryptographically secure manner. We studied the intricacies behind development and deployment of group signature schemes and protocols. The project involved understanding of heavy cryptographic mathematics. We coded an application useful to corporate organization structure in JAVA. Find the presentation, report here.

Computer Networks Summary based Co-operating Proxies : The sharing of caches among web proxies is an important technique to reduce web traffic and alleviate network bottlenecks. We implemented a summary cache protocol where each proxy keeps a summary of the cache directory of each participating proxy, in the form of bloom filter, and checks these summaries for potential hits before sending any queries over bottleneck link.

Wireless Networks Analysis of routing metrics for Wireless Mesh Networks: We tested three metrics ETX (Expected Transmissions), ETT (Expected Transmission Time) and number of hops for paths between two nodes in a 2-hop mesh network. We had deliberately kept one link, in one of the two paths, operating on higher bandwidth and induced noise to test the behaviour of metrics. We found that ETT always outperforms ETX unless it compensates the ill-effects on the path due to noise. This project won the 2nd prize in class project competition.

Quality of Service In Networks Emulation of Differentiated Services in VNUML: We emulated a multi-tier network in VNUML and implemented DS functionalities like classification, marking and dropping. We tested the performance of network for VoIP calls in terms of throughput, delay and jitter for DS-enabled and non-enabled situations. We found that DS-enabled network always has low delay, marginal jitter variations and higher throughput for flows availing the DS services. Find the presentation, report here.

Performance Evaluation Comparison of X-Mac and B-Mac protocols: We emulated the two protocols using multiple threads and measured the energy and latency issues with the use of these protocols. We found that X-Mac always outperforms B-Mac in terms of energy consumed by the network. This project won the 1st prize among the three course projects competing for the prize.

Applied Economics Demand Forecasting in Indian Retail Sector : We surveyed various tools and techniques used for demand forecasting like delphi method and least square regression. We visited a well known firm in retail sector called Haiko and earned insights as to how the demand forecasting done on intuitions in such a firms in practice. Find the presentation, report here.

Seminar Fault diagnosis in Wireless Mesh Networks : The seminar involved a research background as to how we can pinpoint the exact cause of the problem occuring in a multi-hop mesh network. The attribution of fault to a specific root cause helps in ratifying quicker remedy to the problem. The seminar involved fault diagnosis in enterprise as well as long distance mesh networks and dealt with faults like interference, hidden terminals, capture effects, poor power quality problems and the pertinent remedies.

MTP First Stage LO3 (LOw cost, LOw power, LOcal voice) envisions to provide local communication infrastructure in a village to enable applications such as two-way interactive voice, community alerts and stored voice messaging. Considering low income levels and unreliable power quality in the villages, LO3 needs to take many state of the art design decisions. Those include technology to be used, network architecture, choice of hardware to aid voice messaging, network protocols and mobility support. This report, through experimentation, attempts to address some of these design questions. With the low power, low cost features of 802.15.4 platforms, we need to verify whether they have capacity to support our voice messaging needs. As the first topic, we check whether the standard encoding algorithms like ADPCM can be used in accordance with voice traffic deadlines. Given the scarcity of bandwidth associated with 802.15.4 (250kbps), performance of CSMA/CA in mesh topology and the need to support delay sensitive voice application, a contention free, slotted TDMA MAC is explored as the next core topic of the report. LO3 intends to provide limited amount of mobility support. Paging stems from this artifact and as a third topic, we explore the paging design issue in accordance with duty cycled operation of nodes over a multi hop network. Through the experiments, we conclude that the Tmote-sky platform is inadequate to support standard ADPCM algorithm and thus our high quality voice requirements. With the TDMA implementation, we achieve around 130 kbps of throughput over first hop and around 45 kbps of throughput over 3 hops when employing multiple channels. Different architectures for paging mechanism are described in this context. The suitable paging design is currently in exploratory stage. Find the report and presentation here.
I am currently working on LO3 project and my research topic deals with paging mechanism in this scenario to enable mobility. You can get the updates about my project here.
