NETWORK SYSTEM AND DATA TRANSFER METHOD
First Claim
1. A network system that includes a plurality of nodes that include a wireless communication function and that carries out data communication via the nodes, comprising:
- a total link value-calculating unit that calculates, upon receiving data that is a transfer target, based on link values corresponding to a communication quality of the nodes that have transferred the data and radio wave strength among the nodes, a total link value that indicates a quality of a communication path that is used to transfer the data; and
a transferring processor that transfers, based on the total link value that is calculated by the total link value-calculating unit, the data to a destination node.

Abstract
Upon communication nodes receiving data that is a transfer target, based on a link value corresponding to a communication quality of each communication node that has transferred the data and radio wave strength among the communication nodes, a network system calculates a total link value that indicates a quality of a communication path that is used to transfer the data. The network system determines whether the calculated total link value is greater than or equal to a threshold value and based on a determination result, transfers the data to a destination communication node.
