Abstract
Apparatus, methods and computer program products provide quality of service and power aware forwarding rules for mesh points in wireless mesh networks by monitoring frame flow to and from a first mesh point in the wireless mesh network; and in dependence on the monitored frame flow, setting a power management mode of the first mesh point. The first mesh point monitors, for example, the power save mode and mesh deterministic access status of peer modes and selects power save and frame transmission modes in dependence on the monitored information.

A method, comprising:
- at a first mesh point in a wireless mesh network, monitoring a first frame flow between the first mesh point and at least a second mesh point, and monitoring a second frame flow between the first mesh point and at least a third mesh point;
- and
- in dependence on the monitored first frame flow and the monitored second frame flow, setting a power management mode of the first mesh point,
- wherein the second mesh point and the third mesh point are neighbor peer mesh points to the first mesh point and the first mesh point participates in a communication with the second and third mesh points, the communication comprising the first and second frame flows, and
- wherein the setting further comprises determining a first access category corresponding to the first frame flow, determining a second access category corresponding to the second frame flow, and setting the power management mode based on the determined first and second access categories.
An apparatus comprising:
- radio apparatus configured to perform bidirectional communication operations in a wireless mesh network;
- and
- a controller, when the apparatus is operating as a first mesh point, that is configured to monitor, using the radio apparatus, a first frame flow between the first mesh point and at least a second mesh point, and to monitor, using the radio apparatus, a second frame flow between the first mesh point and at least a third mesh point;
- and in dependence on the monitored first frame flow and the monitored second frame flow, to set a power management mode of the first mesh point, wherein to set the power management node further comprises to determine a first access category corresponding to the first frame flow, to determine a second access category corresponding to the second frame flow, and to set the power management mode based on the determined first and second access categories,
- wherein the second mesh point and the third mesh point are neighbor peer mesh points to the first mesh point and controller is further configured, when the apparatus is operating as the first mesh point, to participate in a communication with the second and third mesh points, the communication comprising the first and second frame flows.
A computer program product comprising a computer readable memory medium tangibly embodying a computer program, the computer program, when executed, configured to cause an apparatus to operate as a first mesh point in a wireless mesh network to monitor a first frame flow between the first mesh point and at least a second mesh point, and to monitor a second frame flow between the first mesh point and at least a third mesh point;
- and in dependence on the monitored first frame flow and the monitored second frame flow, to set a power management mode of the first mesh point, wherein the second mesh point and the third mesh point are neighbor peer mesh points to the first mesh point and the computer program, when executed, is further configured to cause the apparatus to participate in a communication with the second and third mesh points, the communication comprising the first and second frame flows, wherein to set the power management mode further comprises to determine a first access category corresponding to the first frame flow, to determine a second access category corresponding to the second frame flow, and to set the power management mode based on the determined first and second access categories.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
- at a first mesh point in a wireless mesh network, monitoring a first frame flow between the first mesh point and at least a second mesh point, and monitoring a second frame flow between the first mesh point and at least a third mesh point;
- and
- in dependence on the monitored first frame flow and the monitored second frame flow, setting a power management mode of the first mesh point,
- wherein the second mesh point and the third mesh point are neighbor peer mesh points to the first mesh point and the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to perform participating in a communication with the second and third mesh points, the communication comprising the first and second frame flows, and
- wherein the setting further comprises determining a first access category corresponding to the first frame flow, determining a second access category corresponding to the second frame flow, and setting the power management mode based on the determined first and second access categories.
