Abstract
A system and method for wireless communication are disclosed. One aspect of the system includes a plurality of wireless devices forming a wireless network. The plurality of wireless devices are configured to wirelessly communicate with one another. Each of the wireless devices includes a device table including a list of one or more of the wireless devices and the directions of the one or more of the wireless devices with respect to the wireless device including the device table. In the wireless system, any one of the plurality of wireless devices is configured to perform device discovery directly with a new wireless device entering the wireless network. The one wireless device is further configured to update the device table therein and to transmit the updated device table to other wireless devices in the wireless network. Other devices in the wireless system can update their device tables, based at least partly on the updated device table without performing device discovery directly with the new wireless device.
