Change Log

• Define the route cost by LQI and weak links
• Hop counts while avoiding weak links
• Several comments
• Default value of weak LQI
• The necessity of the sequence number to prevent
  routing loop
• Interaction between QoS metric and distance
  vector routing
• Lifetime definition
• Link monitoring (route timeout by timers?)
• Weak link indicator by LQI
• Unidirectional links
• RERR for low battery and route cost not
  supported should be avoided
