Node | CH | Explication |
x | u | Node x selects u as CH because it has the lowest metric from its neighborhood. Therefore x becomes a simple node. |
z | z | Node z has no more neighbors therefore it stays CH. |
u | u | Node u becomes CH because it has the lowest metric from its neighborhood. |
t | u | Node t changes its state from CH to a simple node because no node chooses t as cluster head and node u has the lowest metric from its neighborhood |
