## Abstract

Application proxy support over a wireless link between a mobile device and a wireless node is disclosed. Application proxy support is configured to conserve energy and resources and is configured to mitigate delays in a communication environment. Application proxy support can be associated with a wireless node, such as a femto cell, which can provide a coarse-grain wireless application proxy support that can utilize various criteria to buffer data and determine how long to delay delivery of data. Femto cell can provide a fine-grain wireless application proxy that runs application proxies for each mobile device for one or more applications associated with mobile device. The proxy can determine whether to buffer and forward received data to mobile device. The wireless application proxy can respond to network on behalf of mobile device. The proxy can wake up mobile device upon arrival of a significant event associated with a proxied application.
