Due to the growing number of wireless devices, the systems community has placed new emphasis on developing shared spectrum networks. Such networks allow multiple unrelated protocols to share the same band of the radio spectrum, each dynamically adjusting its use based on the local behavior it observes. Many of the most widely-deployed wireless standards - including Wi-Fi, Bluetooth, and Zigbee - operate in shared spectrum networks, and with the recent opening of broadcast television bands for secondary use by networked devices, more such standards are sure to follow. Shared spectrum networks, however, introduce new algorithmic challenges.
