摘要:
Provided is a multi-route routing scheme that supports Quality of Service (QoS) in the wireless mesh network. A method of notifying about and avoiding congestion situation in data transmission in a wireless mesh network and a mesh node may also be provided. Data may be differentially transmitted to multiple routes by obtaining a route congestion level existing in a current multi-hop route and thus, data providing a real-time service, such as a video streaming service, may avoid congested routes and may be promptly transmitted. Multiple queues in a mesh node may be divided into divided queues based on a congestion situation of a transmission route in a network and the divided queues may be transmitted through multiple routes and thus, an efficiency of the overall network may increase.
