Robust Distributed services and networks

• Resiliency and robustness at different levels
• Node
• Architecture
• service
• Key demands
• Light weight/resource efficient
• Self-healing, adaptive, reconfigurable
• Guaranteed performance, sustain function and
  services
• Decentralized?

Node resiliency through Diversity
Key demands Challenges/approaches
3
Adaptive Self-healing Architecture

• Key demands
• Light weight wolution to sustain operation in the
  presence of attacks
• Challenges/approaches
• System of systems models/security/programming
• Light weight components/architecture (due to
  resource constraints)
• Effective monitoring and detection
• Self-healing through aspect oriented programming
  (Multi-level adaptive reconfigurations)
• Decentralized control need to control/guarantee
  behavior
• Resiliency through node diversity

Robust Distributed services

• Key demands
• Resilient and robust network services in addition
  to providing connection.
• Challenges
• Network cost trade off with server load
  distribution (potentially conflicting measure
  service delay vs. network congestion)
• How to address faults
• Dynamic population
• Mobility impact
• Probabilistic connection with MANET
