Mesh Connectivity Layer

• Design
• Multi-hop routing at layer 2.5
• Framework
• NDIS miniport provides virtual adapter on
  virtual link
• NDIS protocol binds to physical adapters that
  provide next-hop connectivity
• Inserts a new L2.5 header
• Features
• Works over heterogeneous links (e.g. wireless,
  powerline)
• Implements DSR-like routing with optimizations at
  virtual link layer
• Link Quality Source Routing (LQSR)
• Incorporates Link metrics hop count, MITs ETX,
  MSRs WCETT
• Transparent to higher layer protocols. Works
  equally well with IPv4, IPv6, Netbeui, IPX,

Services

• Shared broadband internet access
• Ubiquitous access (roaming solved one true
  network)
• Neighborhood watchdog (e.g. video surveillance)
• Neighborhood TiVO
• VoIP, chat
• Neighborhood gaming
• Medical emergency response
• Community events bulletin board
• Shared community resources
• Media repository
• Distributed backup
• Neighborhood eBay
