• Optimization methodology based on ant behaviors,
  optimizing
• Limited Memory
• Limited Processing
• Limited Power
• Limited Radio spectrum

IPv6 Auto-configuration
Is needed when
The interface is initialized at system startup time. The interface is reinitialized after a temporary interface failure. The interface attaches to a link for the first time. The interface is moved from a Sensor Router spectrum to another.
