Abstract:
1. A device that functions as a wireless node in an ad hoc wireless network, the device comprising: a plurality of heterogeneous radios to communicate wirelessly over at least one link on at least one channel of the ad hoc wireless network; and a channel cost metric (CCM) determiner configured to determine a CCM value, the CCM determiner comprising: wherein the CCM determiner determines the CCM value utilizing both the determined ETT value and the determined FAT value such that the CCM value reflects expected transmission time on each channel as weighted by channel utilization; and a joint channel assignment and routing (JCAR) implementer configured to evaluate one or more CCM values determined by the CCM determiner and to jointly switch a channel and a route between wireless nodes in the wireless network to lower the CCM value.
