METHOD FOR FREQUENCY CHANNEL SELECTION OF ZIGBEE NETWORK

摘要

PURPOSE: A frequency channel selecting method of a zigbee network is provided to minimize packet loss and network resource waste by using a table storing the numbers of interference in a frequency channel. CONSTITUTION: An interference detecting table is generated(S101). The interference detecting table records the interference generation number of a heterogeneous network during fixed time in a frequency channel of a zigbee network. The state of the interference is detected in a frequency channel used by a zigbee network(S103). When the interference is generated, a frequency channel is selected by referring to the interference detecting table(S107). The zigbee network is selected as the selected frequency channel (S109). The interference detecting table is updated(S111).
