Abstract
A method and system are described for establishing an end-to-end route for data to traverse a wireless network, including calculating a link cost function, calculating a quantized link cost function using the calculated link cost, function, calculating a quantized cost of each of a plurality, of end-to-end routes for data to traverse the wireless network, wherein the plurality of end-to-end routes include routes between a same set of nodes in the wireless network, wherein, the quantized cost of each of the plurality of end-to-end routes for data to traverse the wireless network is performed using the quantized link cost function and selecting one of the plurality of end-to-end routes, for data to traverse the wireless network based on the quantized cost of each of the plurality of end-to-end routes. Also described is a node in a wireless network configured to participate in the establishment of a bi-directional end-to-end route for data to traverse the wireless network.
