Claim:
1. A node device for wireless communications, the node device being coupled to a plurality of adjacent node devices including a first adjacent node and a second adjacent node, the node device comprising: a memory; and a processor coupled to the memory and configured to: obtain record information from each of the plurality of adjacent node devices, the record information being configured to indicate a ratio of a first number to a second number for each of the plurality of adjacent node devices, the second number representing a total number of packets transmitted from each of the plurality of adjacent node devices respectively to other node devices including the node device and the first number representing a number of packets which are transmitted from each of the plurality of adjacent node devices respectively to the node device, wherein the ratio of the first number to the second number representing a probability that a packet transmitted from the node device to each of the plurality of adjacent node devices is returned to the node device from each of the plurality of adjacent node devices respectively, compare the ratios of the plurality of adjacent node devices respectively with a threshold, transmit the packet toward the first adjacent node, when the packet does not reach the first adjacent node due to a communication failure that occurred between the node device and the first adjacent node device, select, among the plurality of adjacent node devices, the second adjacent node device of which the ratio is lower than the threshold, and transmit the packet to the selected second adjacent node device.
