PATH SELECTION PROCEDURE IN MESH NETWORK AND FORMAT OF PATH REQUEST FRAME THEREFOR

摘要

A method for selecting a transmission path from a source mesh point (MP) to a destination MP in a mesh network is provided. The source MP broadcasts a frame comprising a path request (PREQ) element. According to a power management state of an intermediate MP that receives the frame, the PREQ element comprises power management mode consideration information for controlling forwarding the received PREQ element for the destination MP. A transmission delay due to delay of data requested to be transmitted in real time at the MP operating in the PSM can be prevented.
