Back to GSoC 2023 projects

Project Overview

• Project Name: Dynamic device registration for NetAnim simulation animations
• Student: Raghuram Kannan
• Mentors: Tommaso Pecorella and Manoj Kumar Rana
• Google page: https://summerofcode.withgoogle.com/programs/2023/projects/EpacH0ct
• Project Goals: The project aims to refactor the NetAnim module such that each module willing to use NetAnim will have a .cc and .h file responsible for communication with the NetAnim module, enabled only if NetAnim is active. This will break the dependencies and will allow more flexibility for out-of-tree modules and modules migrating to the AppStore.

Milestones

The GSoC period is divided into two phases. Following are the deliverables according to the proposal:

Phase 1

Duration: Week 1 to Week 6

• Refactor the Csma module and test to see if it works the same as before.
• Refactor the Point-to-Point module and test to see if it works the same as before.
• Refactor the LTE module and test to see if it works the same as before.

Phase 2

Duration: Week 7 to Week 12

• Refactor the Wimax module and test to see if it works the same as before.
• Refactor the Wi-Fi and Internet module and test them to see if it works the same as before.
• Refactor the Uan and Wave module and test them to see if it works the same as before.
• Testing and documentation of work done

Weekly Reports

Community Bonding Period

Duration: May 4 - May 28

• Discussed the proposal ideas and any potential blockers.
• Decided to convert AnimationInterface into a singleton with a proxy in between.
• Added a define for NetAnim in CMake to let us know if NetAnim has been compiled successfully.
• Discussed the need for CreateObject() for the NetDeviceAnim Class (The new class added to the respective net-device modules to connect to NetAnim).

Weekly Report

Week 1 (May 29 - June 4):

• Converted AnimUidPacketInfoMap into a map of net-devices in MR [1].
• Made AnimationInterface into a singleton with a proxy in between as discussed in the Community Bonding Period in MR [2].
• Added a define for NetAnim in CMake in MR [3].

Week 2 (June 5 - June 11):

• Used another approach to convert AnimationInterface into a singleton using the template present in singleton.h because the previous approach had the following issues:
  • Exposed the singleton class.
  • Duplicate API.
  • Forwarding implementation in the AnimationInterface class in a public header.
• Moved the declaration and implementation of the Singleton class to the animation-interface.cc file similar to type-id.cc.
• Added comments for Doxygen for the new function declarations.

Week 3 (June 12 - June 18):

• Started writing an SRS Document for the Project to define the approach.
• Working on issues with MR [4].
• Started working on the first Milestone in Phase 1.

Week 4 (June 19 - June 25):

• Completed the refactoring of the csma module and tested to see if it works the same as before.
• Completed writing the SRS report.

Week 5 (June 26 - July 01):

• Working on doxygen-related issues in MR [5].
• Presented the current state of the project at WNS3 2023.

Week 6 (July 2 - July 8):

• Working on pipeline issues with the proxy-csma-anim branch
• Discussed the need of moving OuputCsmaPacket()
• Discussed if there is a need to Dynamically Register Net-Devices.

Week 7 (Jul 9 - Jul 15):

• Moved the OutputCsmaPacket() and PurgePendingPackets() to the CsmaNetDeviceAnim

Week 8 (Jul 16 - Jul 22):

• Created a MR [6] for the Csma Refactor.
• Started working on the Point-to-Point module.

Week 9 (Jul 23 - Jul 29):

• Fixed issues with MR [7].
• Added suggested changes in the comments of MR.
