Goal

• Defend pair-wise communication channels in MANETs
• Electric-Field-Based Routing (EFR) defends
  against
• Black-hole routers
• Man-in-the-middle attacks
• Byzantine and geographically localized failures
• Service degradation

3
Electric-Field-Based Routing

• With two opposite poles
• Locally apply electric-field equations at each
  node
• Globally define spatially disjoint routes for all
  communicating pairs
• No further route coordination

Research Challenges

• Evaluate EFR under different attacks
• Overcome practical deployment constraints
• Build obstacle/corridor conforming routes
• Balance energy consumptions
• Explore other stateless approaches of
  constructing secure spatially disjoint routes
