Abstract

Various embodiments of systems and methods for data distribution to portable electronic devices are described herein. Initially a data server receives a data download request from one or more portable electronic devices. Next the requested data is divided into a plurality of data portions. Next based on an-hoc network, a data-transfer route between the one or more portable electronic devices and a plurality of portable electronic devices connected to the data server are identified. The data server then forwards the plurality of data portions to the plurality of portable electronic devices connected to the data server. Finally, based on the identified data-transfer route, the requested data from the one or more portable electronic devices to the other portable electronic devices is transferred.
