Distributed Filesystem for Wireless Mesh Networks

Assigned to: Felix Bechstein

Advisor: Anatolij Zubow

Expected Submission: December 2007

Problem Statement

  • Which problem do you want to solve?
    • There is no filesystem only based on DHT for decentralized use, like our BRN.
  • To which domain of Computer Science does this problem relate to?
  • Why is the problem interesting? Why is it difficult?
    • A filesystem is abasic service for many applications on top. It can be used for class- and update-distribution, backup- or storage-service and many more.

Deliverables

  • At the end of the project, what will you have delivered?
    • A basic distributed (high-performance) filesystem, using only the DHT.
    • An interface to that filesystem in fuse or nfs, to mount it.
  • What does it mean that the project was successful?
    • The filesystem's performance is sufficient for class- or upgrade-distribution.

Prior Art

  • Who are your competitors? What are they doing?
  • How is your work different?
  • List of publications related to your topic.

Key Ideas / Project Execution Plan

  • How will you approach the problem?
    • I'll build the filesystem from bottom to top:
      • abstraction to fuse, nfs or similar
      • fs-layer: c# library, with an ioctl-like interface
      • block-layer: abstract the dht to simple blocks/extends variable in size
      • dht-layer: use the DHT
    • All the BRN-magic is done in the DHT, so i'll try to build a clever block structure with some caching to improve everything's speed.
  • On which contributions of others do you depend on?
