  • Track It - A simple Android application to track the position of a parked vehicle

    * In this project, a simple android application called "Track It" was developed. This application can be used for tracking the location of your parked vehicle.

    * The Android SDK, Google Maps API and JAVA programming language were used for this app. This app uses a combination of GPS and Google Maps to help the user locate his/her parked vehicle in a confusing space like a shopping mall parking lot.

    * In this project, a simple android application called "Track It" was developed. This application can be used for tracking the location of your parked vehicle.

    * The Android SDK, Google Maps API and JAVA programming language were used for this app. This app uses a combination of GPS and Google Maps to help the user locate his/her parked vehicle in a confusing space like a shopping mall parking lot.

    * The App's algorithm calculates the speed of the user using GPS and intelligently decides whether the user is on the moving vehicle or parked his vehicle. It automatically creates a check point for the parking spot on the app's map interface. Points are drawn on the map from the parking spot whenever the user is walking away from the location.

    * A combination of distance from the vehicle, map points and discrete beeps help the user to locate his parked vehicle accurately.

  • University Student Management System

    * In this project we designed a database system that could be used in a University. This system consists of information about various departments in the University, Professors and Student community. This system is designed with a concern that it should encompass all the relationship that span between various entities in the database.

    * The E/R Diagram and the relational schema were developed for the system. All BCNF, 4NF violations were removed by decomposing the relations into smaller…

This system consists of information about various departments in the University, Professors and Student community. This system is designed with a concern that it should encompass all the relationship that span between various entities in the database.

    * The E/R Diagram and the relational schema were developed for the system. All BCNF, 4NF violations were removed by decomposing the relations into smaller relations that are in BCNF, 4NF.

    * The relations were created using MySQL. A JAVA program was written to populate the schema with gibberish data in order to simulate a real University data with a reasonable amount of members.

    * Queries were written in order to fetch useful information from the system. The queries comprised of important MySQL functions like JOIN, GROUP BY, DISTINCT, ORDER BY etc.

    * A moderately user-friendly interactive application program front end was developed for this database using JAVA and embedded SQL.

  • Maximum Bandwidth path construction in a large network using a modified Dijkstra's and Kruskal's algorithm in C++

    The maximum bandwidth path construction is a very essential and basic operation in the field of
    network routing. Various algorithms have been proposed for this purpose. In this project, we are going to construct three types of algorithms to study the performance of this problem of finding the maximum bandwidth path. The first two algorithms are implemented by modifying the Dijkstra’s Single Source Shortest path algorithm to solve this problem. We construct two versions of Dijkstra’s. First…

In this project, we are going to construct three types of algorithms to study the performance of this problem of finding the maximum bandwidth path. The first two algorithms are implemented by modifying the Dijkstra’s Single Source Shortest path algorithm to solve this problem. We construct two versions of Dijkstra’s. First one uses the max priority heap or priority queue and the second does not use the heap structure. The third algorithm is constructed by modifying the Kruskal’s algorithm using a heap structure.

  • Sniff and Spoof

    1) Built a simple ICMP and Telnet packet sniffer and an ICMP Reply Packet spoofer that will spoof ICMP replies if it detects an ICMP Echo from any host in the network
    2) Used Pcap libraries and raw socket programming in C for coding

  • Socket Programming hobby Projects

    1) Implemented a simple "Ping" utility using Raw sockets and ICMP packets in C. The utility displays the RTT taken for each ping request to the desired server.
    2) Implemented a simple "Traceroute" utility using Raw sockets and ICMP packets in C. The utility displays the server name, server address, hop count and RTT at each hop step.

  • TAMU Engineering Innovation Center Pop-Up Class Administrator Website(Ruby on Rails)

    -

    * Designed a website for the TAMU EIC Department for report generation and student course registration
    * Implemented the backend using MySQL and wrote a Ruby code for doing API Calls to eventbrite.com and populate the student and class details to the database.
    * Implemented the frontend by writing rails views using HTML, HAML & CSS and created the corresponding controllers.

  • Performance analysis of Concatenated Reed-Solomon and Convolutional Codes

    -

    Simulated the concatenated coding system with an outer Reed-Solomon code and inner Convolutional code(common coding system used by NASA/JPL and in the Digital Video Broadcasting(DVB) standard). The (255,239,17) RS Code and a rate ½ Convolutional code with constraint-length 7 was used for the entire simulation. The Viterbi algorithm and a combination of Berlekamp-Massey, Forney’s algorithm & Chien search were used for decoding the Convolutional and RS code respectively. MATLAB was used…
