Abstract

A wireless device resource sharer (WDRS) proxies incompatible communications between wireless devices. A wireless network may be formed allowing both compatible and incompatible wireless devices to communicate therebetween. The WDRS allows incompatible wireless devices to appear as compatible devices. In this way, the WDRS may be “invisible” to such devices allowing the wireless devices to be part of a network of “compatible” devices. The WDRS includes physical interfaces to communicate with compatible and incompatible wireless devices in accordance with various wireless network physical layers. The WDRS also includes a proxy server to proxy incompatible network application layer protocols between wireless devices. The WDRS may also share storage and processing resources with wireless devices. A policy manager within a wireless device regulates resource sharing with other devices. A wireless device may also share resources directly with other wireless devices, and may automatically and intelligently select network connectivity.
