Abstract
A system has a group of nodes that perform multi-hop communication therebetween and a communications apparatus that communicates with a node included in the group of nodes. The node adds to data transmitted by the node, a hop count updated each time the data is transferred by the multi-hop communication and a reference hop count for the data to be transferred from the node to the communications apparatus, and transmits the data. The communications apparatus, when receiving the data, compares the reference hop count and the hop count added to the data, and based on a result of comparison, determines whether failure has occurred at a given node in the group of nodes.
