Presentation Transcript

  1. IGF: A robust state-free communication protocol for sensor networks B.M. Blum, T. He, S. Son, J.A. Stankovic UVa Tech Report 2003

  2. Implicit Geographic Forwarding • Tackle the rapid dynamics found in WSNs • To deal with • Power Down Nodes (Sleep mode) • Node Mobility • Node Failure • Scale • Lazy Binding (to the nth degree) • State Free – no routing tables

  3. Lazy Binding Concept Defer mapping network topologies into volatile states (e.g. route state) as late as this operation allows (last 50 microsec in IGF).

  4. IGF Asleep IGF is a combined Routing/MAC protocol Eligible nodes - 60 degree cone (shift cone if necessary) RTS - set timer based on distance and energy remaining Moving Away
