Abstract

A plurality of mobile devices is provided including a first mobile device of the plurality of mobile devices that serves as a relay for communication between a second mobile device of the plurality of mobile devices and a third mobile device of the plurality of mobile devices. The first mobile device is identified as the relay based on a social trust relationship formed between the first mobile device and the second mobile device. A D2D network is formed between the first mobile device and second mobile device. A communication channel is provided to the second mobile device from a second cellular network. A portion of the communication channel is allocated to the second mobile device using the D2D network to improve cellular transmission between the second mobile device and the third mobile device.

First claim

What is claimed is:

1. A computer program product usable with a programmable computer processor having a computer readable program code embodied in a non-transitory computer usable medium, defining machine-readable instructions for providing cooperative networking comprising:
providing a plurality of devices included within a cooperative device-to-device (D2D) communication system, a first device of the plurality of devices configured to:
serve as a relay for communication between a second device of the plurality of devices and a third device of the plurality of devices, the second device communicating using a bandwidth, wherein as the relay the first device provides additional bandwidth to the bandwidth of the second device to assist with data transmission between the second device and the third device; and

forming a D2D network between the first device and the second device, wherein the second device splits its data traffic into a plurality of data streams including a first data stream between a base station and the second device that provides first bandwidth used by the second device for the data transmission with the third device, and a second data stream provided to the second device by the first device that provides a second bandwidth for the data transmission from the second device to the third device, the second device aggregating the first bandwidth and the second bandwidth to improve the data transmission with the third device.

2. The computer program product of claim 1 , further comprising forming a D2D network between a fourth device of the plurality of devices and the second device.

3. The computer program product of claim 2 , wherein the D2D network comprises Wi-Fi direct transmission.

4. The computer program product of claim 1 , wherein the third device includes a video content server hosting a plurality of video data files.

5. The computer program product of claim 1 , further comprising:
providing a first subscriber identification module(SIM) card and a second SIM card on the second device; and
aggregating bandwidth available to the first SIM card with bandwidth available to the second SIM card.

6. The computer program product of claim 1 , further comprising:
forming an additional D2D network between the second device and a fourth device, the fourth device configured as an additional relay device to provide additional bandwidth assistance to the second device such that both of the first device and the fourth device define relays to the second device.
