Abstract
Systems and methods directed towards improving reliability for wireless networks. Selective polling techniques are utilized to selectively poll stations within a wireless network in order to ensure that a station failing to properly transmit data is given an opportunity to rectify the transmission failure. The selective polling techniques can be applied to any polling-based system, thus maintaining backwards compatibility with legacy systems.
