A ZigBee network system, method with roaming function, and computer readable medium thereof are provided. The ZigBee network system comprises a first node, a second node, a coordinator and a first roaming node. The first node, the second node and the coordinator are connected directly or indirectly. The first roaming node connects to the first node wirelessly. The method comprises the following steps. The first roaming node transmits a roaming-request packet when the first roaming node roams within a connecting range of the second node. The second node transmits a roaming-identify packet in response to the roaming-request packet. One of the first node and the coordinator transmits a roaming-confirm packet in response to the roaming-request packet. The second node transmits a roaming-response packet in response to the roaming-confirm packet. The first roaming node connects to the second node wirelessly after the first roaming node receives the roaming-response packet.
