  • Publication number: 20170142602
    Abstract: A first node included in a first layer determines whether there has occurred a failure in a sink node included in a second layer subordinate to the first layer. The first node requests a second node included in the second layer to collect information of a third node included in a third layer subordinate to the second layer when the first node determines that there has occurred a failure in the sink node. The first node determines a fourth node serving as a substitute for the failed sink node included in the second layer on a basis of the information of the third node collected by the second node.
