Abstract

A system configured to manage battery energy of a mobile device includes a primary mobile device and at least one peer device. The primary mobile device includes a power unit, a main communication module to electrically communicate with a peer device, and a peer assisted module in electrical communication with the power unit and the main communication module. The peer assisted module determines an energy level of the energy unit, and determines a task to be executed by the peer device. The peer device receives the task transmitted from the primary mobile device. The peer device further includes a peer process management module that executes at least one computation that completes the task, and communicates a completed task to the primary mobile device.

Claims

1. A system configured to manage battery energy of a mobile device, comprising:

a primary mobile device comprising;

a power unit configured to power the primary mobile device;

a primary process management module configured to determine at least one application stored on the primary mobile device and to determine a task associated with the at least one application;

a main communication module configured to electrically communicate with a peer device different from the primary mobile device; and

a peer assisted module in electrical communication with the power unit and the main communication module, the peer assisted module configured to determine an energy level of the power unit, and to transmit the task from the primary mobile device via the main communication module; and

at least one peer device comprising;

a peer communication module configured to receive the task from the primary mobile device; and

a peer process management module in electrical communication with the peer communication module, the peer process management module configured to execute at least one computation that completes the task, and to communicate a completed task to the primary mobile device in response to completing the at least one computation,

wherein at least one of the primary process management mobile and the peer device determines a monetary value based on an amount of computations and a duration of the computations, and

wherein the peer assisted module determines a cost value based on the amount of computations for completing the task and the duration of the computations, and transmits the task to the at least one peer device when the cost value is below a cost threshold value, the peer assisted module transmitting the task from the mobile device to a peer device when the cost value is below a cost threshold value, the monetary value is below a monetary threshold value, and the level of energy available to the mobile device is below a predetermined threshold level.

2. The system of claim 1, wherein the peer assisted module outputs an offload request to transmit the task to the at least one peer device.

3. The system of claim 2, wherein the peer communication module of the at least one peer device is configured to detect the offload request and to receive the task in response outputting an accept command to the primary mobile device.

4. The system of claim 3, wherein the primary process management module includes a task scheduler configured to locally execute the task in response to at least one of the cost value exceeding a cost threshold and a failure to receive the accept command.

5. The system of claim 4, wherein the primary process module receives an input from the user indicating that at least one application includes a task to be communicated to the peer device for execution.

6. The system of claim 5, wherein the primary mobile device includes an operating system that operates the primary mobile device, and wherein the main process management module and the peer assisted module are integrated in the operating system.

7. The system of claim 5, wherein the peer assisted module is implemented as a peer assisted application module that is stored separately from an operating system of the primary mobile device, the peer assisted application module configured to receive a task from a peer assisted application and to communicate with the power unit and main communication module via a data communication socket interface.

8. A primary mobile device to offload at least one task of a stored application to reduce energy consumption, the primary mobile device comprising:

a power unit configured to power the primary mobile device;

a main communication module configured to electrically communicate with a peer device that is different from the primary mobile device; and
