Problems solved by technology

[0007] One problem with current energy saving methods is that an energy saving grid node needs to receive beacons from all of its peers, a process that can result in considerably longer wake times, and most of the time, given the duration of beacons and their transmission frequency Set the TIM bit

Embodiment Construction

[0024] The various aspects are described below with reference to the drawings. In the following description, for ease of explanation, a large number of specific details are given to provide a comprehensive understanding of one or more aspects. However, it is obvious that the aspects can also be implemented without these specific details.

[0025] The terms "component", "module", "system", etc. used in this application are intended to include computer-related entities, such as but not limited to hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to: a process running on a processor, a processor, an object, an executable program, a thread of execution, a program, and / or a computer. For example, both an application program running on a computing device and the computing device may be components. One or more components may be located in a process and / or thread in execution, and a compon...

Abstract

Methods and apparatus for implementing power saving in mesh nodes include transmitting a receive window start frame prior to each awake period. The receive window start frame is a short frame, and nodes in the mesh network passively monitor for this frame. Upon detection, a mesh node can transmit data to its destination during its awake period.

Description

[0001] This application is a divisional application of the patent application of the same name with the application number 200980115389.1 filed on April 30, 2009. [0002] Claim priority according to 35U.S.C.§119 [0003] This patent application claims the priority of provisional application No. 61 / 049,164 filed on April 30, 2008, entitled "Methods and Apparatus for Power Saving for Mesh Nodes" (Methods and Apparatus for Power Saving for Mesh Nodes) , The application has been assigned to the assignee of this application, and is expressly incorporated into this application by reference.
