Final presentation survey p2p-videostreamingwmn

  1. 1. Survey on P2P Video Streaming over Wireless Mesh Networks DEMETRIOU, CHARIS NASIR, MUHAMMAD ANIS UDDIN SEVERIEN, ANTONIO RODRÍGUEZ GARCÍA, ANTONIO1
  2. 2. Overview• Proposed work• Introduction• Wireless Mesh Networks Challenges• Proposed Optimizations/Solutions• Related Work• Conclusion• Q&A
  3. 3. Proposed Work• P2P Video Streaming...• ...over WMNs• Challenges• Solutions/Architectures• Optimization
  4. 4. Peer to Peer• Scalable• Reliable• No central administration• Low cost• 70% internet traffic
  5. 5. P2P Video Streaming• New trend• Reliable• Efficient• Content Streaming• Live Streaming
  6. 6. Wireless Mesh Network• Cost-effective• Self organizing• High capacity• Low maintenance cost• Easy deployment
  7. 7. P2P over WMNs
  8. 8. Challenges• Scarce resources• Churn• Quality of Service (QoS)• Quality of Experience (QoE)• Latency• Mobility• No underlay awareness
  9. 9. Proposed Optimizations/Solutions• Streaming Architecture• Peer Selection• Cross Layer• Opportunistic Caching• QoS / QoE• Resource Usage• Replication
  10. 10. Streaming ArchitectureTree-based Mesh-based
  11. 11. Peer Selection• Receiver based Rate allocation and Peer Selection (RPS)• Latency based• Geo-location based• Peer resources based• ALTO service
  12. 12. Cross Layer Design• Swarm Intelligence• ...focusing on scalability and bandwidth for MANETs• Push-and-pull approach• Optimal next-hop based on probabilities; derived from swarm intelligence algorithm (ARA)• WMN have similar dynamic nature
  13. 13. Opportunistic Caching• Local caching• Cross-layer interaction• Reduction of duplicated content from 46,7% to 1,3%
  14. 14. Quality of Service/Experience• Multi-gateway approach with Multiple Description Coding
  15. 15. Quality of Service/Experience• Collaborative resource exchanges• 3D wavelet video codec• Path discovery using AODV• Video compression algorithm
  16. 16. Resource Usage• Hybrid TCP• ALTO server to group neighboring nodes• Frame rate adaption according to bandwidth• Avoiding duplicated content• Peer selection
  17. 17. Replication Scheme• Home-to-home video clip replication scheme (H2-VIP)• Deals with online/offline behavior• Consider popularity of video• Extra replicas to increase the availability
  18. 18. SummaryOptimizations vs. Problems
  19. 19. Related Work• P2P Video Streaming• P2P content sharing over WMNs o discussion of overlay and mesh network combination o proposed a venture investment scheme to provide better network performance• MANETs o does not provide acceptable QoS, not viable for streaming o high packet losses
  20. 20. Related Work• VANETs o Address the dynamic nature of Vehicular Ad-Hoc Networks (high speeds, frequent topology and connectivity changes, low throughput and strict delay requirements) o Streaming Urban Video o next-hop selection is based on current position and received power o use of graph-coloring theory to detect collisions
  21. 21. Conclusions• P2P Video Streaming over WMN can be reliable and cost effective solution• Scarce resources, churn, mobility, no-underlay awareness makes problem more challenging• Different schemes can be used to solve the problems• Uniting solutions for different problems on one system
