20140045485 | SYSTEM AND METHOD OF POWER SAVINGS FOR MOBILE DEVICE USING CLOUD SERVICE - A method and system for power saving of a remote device determines whether to offload the application to a cloud server by comparing the cost of computing the application data in the remote device to that of computing the same application data in a cloud server. If the former cost is greater, then the remote device offloads the application to a cloud server. The method takes into the account the parameters such as distance between the remote device and the access network, the power required to transmit the application data from remote device to the cloud server for calculating the power required for computing the application data in the cloud server. | 02-13-2014 |
