ad-hoc networks: Security of routing in wireless networks
•Gradual development of trust relationships
•What use cases are valid if certain simpler
implementations
•Simpler node states
•Multiple path routing
•Evaluation of existing implementations
•Real-time application performance
•Comparison of routing methods
•New Scheduling for packet forwarding

• Security info UI for users
• Application usage policy definitions
• Adaptable to user’s knowledge level
• Context aware security (How much to automate and when?)
• On/Off: VPN Internet access, Plain Internet access
• WAN, LAN, PAN usage according to availability and policy
