Projects

  • Collaborative Editor with Versioning System(Android App)

    • Android Application to collaborate and edit a shared file between different android clients (similar to Google Docs).
    • Used Differential synchronization algorithm for proper collaboration.
    • Handled data consistency, network and packet failure.
    • Added version control feature to retrieve back older version of data with respect to timestamp.

  • Distributed Leader Selection - Bully's Algorithm

    • Implemented Bully's algorithm to choose a leader process among the set of processes running in different nodes in a distributed clustered environment.
    • Leader process will be selected uniquely with the highest process Id and all process will reach to consensus.
    • Leader process can be used as a bootstrap server process.

  • Distributed Mutual Exclusion - Raymond's Algorithm(Distributed Systems)

    Implemented Distributed Raymond's algorithm which runs across N machines in a cluster. It ensures multiple processes running in different servers can't enter the Critical Section(CS) at the same time and provides proper mutual exclusion to access a distributed resource.

  • Distributed Clock Synchronization- Vector Timestamp,Chandy-Lamport algorithm (Distributed Systems)

    • Implementation of distributed logical clock synchronization algorithms Vector TimeStamp(Vector clock) and Chandy-Lamport Snapshot algorithm to order the events in a process based on their occurance across multiple servers.

    See project

  • Distributed Mutual Exclusion - Ricart & Agrawala Algorithm(Distributed Sytems)

    • Implemented Distributed Ricart-Agrawala algorithm which runs across N machines in a cluster.
    • Ensured multiple processes running in different servers can't enter the Critical Section(CS) at the same time and provides proper mutual exclusion to access a distributed resource.

  • File Retrieval and Replication across Distributed Servers using Random Tree(Distributed Systems)

    • Implemented and maintained a random tree across multiple server nodes to retrieve a file and replicate files based on file hit popularity within the server nodes.
    • Virtual tree structure will be internally maintained for each file and it will be replicated based on the file hits.

    See project

  • Implementation of Chord Distributed Hash Table version across Multiple servers(Distributed Systems)

    • Implemented a distributed Hash Table(Chord) to dynamically store files on different nodes in a cluster based on their hash values.
    • Added features which allows node to join,leave dynamically and files can be inserted and searched based on shortest path from the source peer.
    • Made the DHT highly scalable to add any number of nodes.

    See project

  • Mail Transfer Application-SMTP, POP3(Computer Networks)

    • Implemented SMTP and POP3 protocol to create a mail application using Java.
    • Developed protocol functionalities as described in RFC.
    • Mail application is designed in such a way even to communicate with Gmail application.

    Other creators

  • Implementation of TCP Tahoe with UDP(Computer Networks)

    • Implemented a TCP functionality with congestion control mechanism similar to TCP Tahoe with proper acknowledgement, flow control, handling packet loss etc.. using UDP communication.

  • Parallel Single Source Shortest Path using Java PJ2 Library(Parallel Computing)

    • Implemented and researched on solving Single Source Shortest Path algorithms in parallel on multiple cores to attain better performance.

  • Routing Information Protocol(Computer Networks)

    • Implemented a Distance Vector Routing protocol similar to RIPv2.
    • Created a local network to find the shortest path between the nodes within the network by updating individual router's routing table.

    See project

  • Blind Control System(IoT)

    • Android application to control IoT systems.
    • Blind Control System which changes its state based on temperature and ambient values measured by Raspberry pi.
    • Used temperature and pressure sensors to gather real time data.
    • Fuzzy based changes based on a set of fuzzy rules input passed from an android application.

  • Distributed Computation on Multiple Raspberry Pi(Distributed Systems)

    • Developed an application which can sort and find average of a very large dataset by distributing and processing it in different nodes in the cluster.
    • Handled proper completion of task using master-slave architecture, networking, fault tolerance by dynamically controlling nodes that enters or leaves the cluster.

  • Re-Modelling Mediation Server module

    Re-Modelled the complete architecture of a server module by including main features like dynamically loading and unloading classes at run time by creating user-defined class loader, performing thread analysis, handling garbage collection and controlling several runtime features in Java.

    • JVM level programming.
    • Worked with user-defined application class loaders.
    • Multi-threading
    • Object oriented development.

    Other creators

  • Framework for Reprogrammable In-network processing in IoT systems

    -

    • Involved lot of research on SDN and OVS to adapt it into IoT systems.
    • In-network Processing in IoT Systems.
    • SDN based IoT Framework.
    • Used Open-vSwitch as a software switch.
    • Implemented a IoT environment with a set of odroid machines and routed the packets based on the flow rules from the centralized SDN Controller.

    SDN Controller : Floodlight
    OpenFlow switch : Open-vSwitch
