ENHANCED POWER REDUCTION IN MESH NETWORKS

摘要

A method for a mesh network is disclosed. The mesh network comprises a first station, a second station and one or more intermediate stations. The communication within the mesh network is transmitted on a plurality of communication channels.;The method comprises initiating a communication by the first station with the second station of the mesh network. The first station, the second station and the one or more intermediate stations together define a mesh path for the communication.;The method also comprises defining by the first station a quality of service—QoS—class which indicates a desired level of quality of the communication.;The method continues with determining available communication channels out of the plurality of communication channels based on the QoS and setting by the first station a limited number of mesh awake windows—MAW—as available for each available communication channel based on the QoS class.;Then the first station, according to the method, defines a MAW map comprising the available MAWs for each available communication channel, embeds the QoS class and the MAW maps in the PREQ frame and broadcasts a path request—PREQ—frame comprising the QoS class and the MAW maps to the second station during a Mesh Management Window—MMW. Also disclosed is a first, second and intermediate station as well as a respective method for a first, second and intermediate station

1. A method for a mesh network comprising a first station, a second station and one or more intermediate stations, wherein communication within the mesh network is transmitted on a plurality of communication channels, wherein the method comprises:
initiating a communication by the first station with the second station of the mesh network, wherein the first station, the second station and the one or more intermediate stations define an mesh path for the communication; defining by the first station a quality of service—QoS—class indicating a desired level of quality of the communication; determining available communication channels out of the plurality of communication channels based on the QoS; setting by the first station a limited number of mesh awake windows—MAW—as available for each available communication channel based on the QoS class; defining a MAW map comprising the available MAWs for each available communication channel; embedding by the first station the QoS class and the MAW maps in the PREQ frame; and broadcasting, by the first station, a path request—PREQ—frame comprising the QoS class and the MAW maps to the second station during a Mesh Management Window—MMW.
