  • 3. • Opportunistic Networks are type of Mobile Ad- hoc Networks(MANET). • Message delays are accepted. • There are a lot of routing protocol mechanisms that have been designed for ON • Synthetic traces are widely used to evaluate ON E.g. : ONE simulator Motivation There are a lot of papers which describes virtual data storages over distributed systems. We can find several storage protocol implementations for MANET as well. But….. According to the best of our knowledge there is not any storage mechanism which uses opportunistic properties September 03, 2015 Weerasooriya W.A.A.C.P. 11002192

  • 6. Modeling a persistent data storage on opportunistic networks making maximum use of opportunistic properties Research Goal September 03, 2015 Weerasooriya W.A.A.C.P. 11002192
  • 7. Research Questions Q1: What is the best way to capture Social network properties in ON? Q2: What is the best persistent storage mechanism for MANET that can be adjusted to use with opportunistic properties of nodes? September 03, 2015 Weerasooriya W.A.A.C.P. 11002192
  • 8. Scope • Synthetic traces- limitations( no. of subjects, simulations area/time) Assumptions: It’s better to see the problem in the easiest way and deriving a solution. Then we can go more deeper in to the problem, removing assumptions one by one. 1. No peer failures 2. Number of nodes are fixed 3. One Writer- Many Readers 4. No reading while writing 5. Write globally- Read locally 6. Security etc. September 03, 2015 Weerasooriya W.A.A.C.P. 11002192

  • 10. From Proposal Defense •BitTorrent Protocol: In the very early phase of our problem we only consider single variables. After successful evaluation of this system we try to focus on stream data. September 03, 2015 Weerasooriya W.A.A.C.P. 11002192

  • 19. To-Do List: Implementation • Implementation of the Routing protocol which uses Opportunistic properties. • Implementation of the Virtual Storage • Our task should be carried out towards stream data also September 03, 2015 Weerasooriya W.A.A.C.P. 11002192
  • 20. To-Do list: Evaluation • Evaluate the success rate: latest copy percentage • Time to get the latest copy • Energy consumption • We have to evaluate our model using a routing protocol which does not use opportunistic properties. • At the same time have to evaluate using a mobility model which does not exhibit opportunistic behavior: Random way point September 03, 2015 Weerasooriya W.A.A.C.P. 11002192
