METHOD AND APPARATUS OF INTERFERENCE AVOIDANCE BASED ON MULTI TRANSMISSION AND RECEPTION

摘要

The present invention relates to a method and a device for avoiding interference based on a multi-transceiver in a wireless communications system. According to the present invention, a sensor node includes multi-transceiver unit running a channel interference avoidance operation in a wireless sensor network. The sensor node includes: a first wireless transceiver unit which inspects the interference occurring in channel A; a second wireless transceiver unit which inspects the interference occurring in channel B; and a central control unit which assigns channel A among the channels included in channel group A to the first wireless transceiver unit and channel B to the second wireless transceiver unit among the channels included in channel group B. The central control unit transmits or receives data through the wireless transceiver unit assigned with the channel without interference among the channel A and channel B. The present invention can search for available channels through wireless multi-transceiver and conducts wireless communications operation. Thus, continuing wireless communications operation through the available channel of another wireless multi-transceiver unit, and preventing the transmission delay caused by the interference without changing the channel of the wireless transceiver unit even when the interference occurs in the channel of the wireless multi-transceiver.
