Wireless terminal, importance generating method, and wireless communication system

A wireless terminal of a network system in which routes amongst a plurality of nodes are dynamically adjusted according to an environment, wherein the wireless terminal forms a target node forming a final destination of data sent from a sending node, and the wireless terminal comprises:

• a processor configured to perform a process including
• storing, in a memory, a partitioning point set of partitioning points where nodes partition routes within the network system, by checking the partitioning points;
• and
• sending a packet including the partitioning point set to other nodes mutually coupled to the wireless terminal.

An importance generating method for generating an importance of each of a plurality of nodes in a network system in which routes amongst the plurality of nodes are dynamically adjusted according to an environment, the importance generating method comprising:

• storing in a memory, by each of the plurality of nodes, a partitioning point set of partitioning points where the plurality of nodes partition routes within the network system, by checking the partitioning points;
• sending, by each of the plurality of nodes, a packet including the partitioning point set to other nodes mutually coupled to the wireless terminal;
• computing, by a target node that forms a final destination of data sent from a sending node, a partitioning probability indicating whether transmission fails by partitioning a location with respect to each pair of a sending source node and a sending destination node, based on a partitioning point set included in a packet received from a relaying node within the network system, wherein the partitioning point set includes partitioning points where nodes partition routes within the network system;
• and
• generating an importance representing an effect of a failure of the relaying node on the network system by a transmission failure probability.
