LOCATION ESTIMATION DEVICE AND LOCATION ESTIMATION METHOD FOR ESTIMATING LOCATION OF INTERFERENCE SOURCE

摘要

A wireless communication network system includes: a location estimation device includes: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: collecting information, for each wireless device in a pair of wireless devices communicating with each other in the wireless communication network, as to the number of occurrences of duplicate reception caused by the data retransmission performed when the reception acknowledgement does not reach the transmitting wireless device; and estimating the location of an interference source of radio wave in a wireless communication network based on the collected information as to the number of occurrences of duplicate reception such that the location of the interference source is closer to one of wireless devices in the pair with a less number of occurrences of duplicate reception than to the other one of the wireless devices in the pair.

主权项

1. A wireless communication network system comprising:
a plurality of wireless devices, each device operates as one of a transmitting wireless device or a receiving wireless device;
wherein the receiving wireless device configured to receive data from the transmitting wireless device and to return a reception acknowledgement signal to the transmitting wireless device after receiving the data;wherein the transmitting wireless device configured to transmit the data to the receiving wireless device and to retransmits the data to the receiving wireless device when the reception acknowledgement signal does not reach the transmitting wireless device; a location estimation device comprising:
a processor; anda memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute:collecting information, for each wireless device in a pair of wireless devices communicating with each other in the wireless communication network, as to the number of occurrences of duplicate reception caused by the data retransmission performed when the reception acknowledgement does not reach the transmitting wireless device; andestimating the location of an interference source of radio wave in a wireless communication network based on the collected information as to the number of occurrences of duplicate reception such that the location of the interference source is closer to one of wireless devices in the pair with a less number of occurrences of duplicate reception than to the other one of the wireless devices in the pair with a larger number of occurrences of duplicate reception.
