Abstract:
1. A computer-readable storage medium encoded with computer-executable instructions for an access point of a first wireless network to perform steps for coordinating bandwidth usage of a frequency channel shared by nodes in the first wireless network and nodes in a second wireless network, the first and second wireless networks having overlapping ranges of wireless transmission, wherein the nodes of the first wireless network and the nodes of the second wireless network are unable to effectively communicate with each other, the steps comprising: receiving registration from nodes of both wireless networks within range of the access point; sending first poll signals each for signaling a time slot for at least one node in the first wireless network to transmit over the frequency channel; and sending second poll signals each for signaling a time slot for at least one node in the second wireless network to transmit over the frequency channel, wherein the first wireless network is an infrastructure network and the second wireless network is an ad hoc network.
