Wireless mesh networking with multiple simultaneous transmissions by nearby network nodes

摘要

A wireless mesh network enables multiple devices near each other to transmit simultaneously, thus allowing increased network bandwidth. Prior to transmitting, a device may determine various parameters of the wireless medium on which it desires to transmit. For example, the device may determine whether the intended recipient device is close enough, and verify that any other transmitting and receiving devices are far enough away. If these or any other suitable criteria are met, the device can transmit simultaneously with other devices in the vicinity.

主权项

1. A method of controlling wireless transmissions of a first device into a wireless medium, the method comprising:
obtaining a first wireless medium parameter that characterizes a communications path between the first device and a second device; determining a range indicator for the first wireless parameter, the range indicator being:
a first value if the first wireless medium parameter falls within a first range;a second value if the first wireless medium parameter falls within a second range; anda third value if the first wireless medium parameter falls within a third range, wherein the third range is between the first and second ranges, wherein the first value represents a greater separation between the first and second devices than the third value, and wherein the third value represents a greater separation between the first and second devices than the second value; obtaining a second wireless medium parameter that characterizes a communications path between the first device and a third device; and selectively controlling, by the first device, the wireless transmission of the first device into the wireless medium based on the determined range indicator and on the second wireless parameter.
