Wireless network device, wireless network system and method of controlling selection of routings

摘要

Embodiments of the present invention disclose a wireless network device, a wireless network system and a method of controlling selection of routings. A wireless network device comprises: a latency information storage module for pre-storing routing latency information for routing from the wireless network device to other nodes in a network; a latency requirement determination module for determining transmission latency requirement of transmitting data packets from the wireless network device to a destination node according to transmission latency requirement information carried in the data packets after obtaining the data packets to be transmitted; a query module for querying available routes from the wireless network device to the destination node, and the pre-stored latency information corresponding to the available routes; a route selection module for selecting a route most approximate to the determined transmission latency requirement from the available routes according to a query result of the query module, to transmit the data packets. According to the approach, it is able to transmit data packets to a destination node within a stable latency range, thus improving the service quality.
