Abstract:
1. A wireless communication device which transmits data over a communications link to a plurality of destination nodes by time division multiplexing for dividing a communication period of the data into a plurality of communication slots the device comprising: a storage section including a transmission queue region that stores unsent data, comprising data not previously sent and data previously sent but not received, which is to be sent to the destination nodes therein; a communication controller comprising: a communication performance situation evaluating section configured to evaluate a communication performance situation of each of the destination nodes; and a communication slot controller configured to: wherein the auxiliary retransmission slot is used for retransmission to a specified destination node such that the retransmission of the unsent data previously sent and not received to the specified destination node is separate from the communication slots and retransmissions slots and does not deteriorate the communication performance situations of other destination nodes, wherein the communication performance situation evaluating section is configured to evaluate a communication error rate of each of the communication nodes, wherein the communication slot controller allocates the unsent data subjected to the specified destination node to the auxiliary retransmission slots, and the communication slot controller allocates the unsent data subjected to remaining destination nodes except the specified destination node to the retransmission slots, and wherein the communication slot controller sets a destination node whose communication error rate exceeds a threshold value as the specified destination node.
