比如：
1）the Sleepy End Device can and will select another Parent Router if its Parent Router is unavailable. As a result, this transition should not be visible to the user.
2）
The Leader is elected and if the Leader fails, another router or Border Router becomes the Leader. It is this autonomous operation which ensures there is no single point of failure.
Leader什么作用？
A router or Border Router can assume a Leader role for certain functions in the Thread Network. This Leader is required to make decisions within the Thread Network Partition. For example, the Leader assigns router addresses and allows new router requests.
Leader是怎么被选出来的?
