Predictive Replica Placement in FogStore - A Simulation Framework

---

Structure:

• geolife-data: location of the raw Geolife Data
• geolife-data-transformed: populated by the me.mbe.prp.TransformGeolife main method in the test module
• src
  • main: code of the framework, algorithms, etc.
    • algorithms
    • base: helper methods
    • core: framework
    • data
    • metrics
    • network
    • nodes
  • test: code for the evaluation
• stats-out: evaluation results saved here

---

Setup:

• Clone repository
• Setup gradle
• Copy the Geolife Data into the geolife-data folder.
• Run the me.mbe.prp.TransformGeolife main method in the test module
• Run the evaluations in me.mbe.prp.geolife.Evaluation
• Results can be found in the stats-out directory

Algorithms:

• Baseline
  • me.mbe.algorithms.Alg000: Store data on all nodes at all times: Section 5.1 of the thesis
  • me.mbe.algorithms.Alg001: Store data only on closest node when application active: Section 5.1 of the thesis
• Next Node Prediction
  • me.mbe.algorithms.nextnodepred.Alg003: (Multi Order) Markov Model: Sections 5.2.1 and 5.2.2 of the thesis
  • me.mbe.algorithms.nextnodepred.Alg004: Variable Order Markov Model: Section 5.2.3 of the thesis
  • me.mbe.algorithms.nextnodepred.Alg008: Store also on some neighboring nodes: Not mentioned in the thesis
  • me.mbe.algorithms.nextnodepred.Alg012: Fusion Multi Order Markov Model: Section 5.2.4 of the thesis
• Startup Prediction
  • me.mbe.algorithms.startuppred.Alg011: Store for short pauses: Section 5.3.1 of the thesis
  • me.mbe.algorithms.startuppred.Alg013: Do not store anything after shutdown: Used together with the algorithms for next node prediction: Not mentioned explicitly in the thesis
  • me.mbe.algorithms.startuppred.Alg014: Store if short pause predicted: Section 5.3.2 of the thesis
  • me.mbe.algorithms.startuppred.Alg015: Clustering of startup times for long pauses: Not mentioned explicitly in the thesis, just as a side note in section 7.2.3 and in chapters 8 and 10
