Abstract:
1. A network node, comprising: at least one transceiver for transmitting and receiving signals; and at least one controller, the at least one controller being operable to create a network information table by: determining link conditions from local link conditions to produce determined link conditions, the determined link conditions including transmission rate information, link efficiency information, and node delay information for each of a plurality of available links to the network node; receiving determined neighboring link conditions from neighboring network nodes available to the network node, wherein the determined neighboring link conditions include transmission rate information, efficiency information and node delay information for links of each of the neighboring network nodes; creating the network information table based on the determined link conditions and the determined neighboring link conditions; transmitting the network information table to the neighboring network nodes; and when the determined link conditions or the determined neighboring link conditions indicate a network change condition: updating the network information table with the determined link conditions and with a time stamp indicating a table update time so as to facilitate compensation for possible errors in the network information table; and transmitting the updated network information table to the neighboring network nodes; and determining a cost function associated with each of the plurality of the available links, wherein the cost function calculates a cost of each of the plurality of the available links by summing a radio transmission time at each of the plurality of the available links, wherein the radio transmission time is calculated from a quotient of a packet size of a packet and the transmission rate information multiplied by the link efficiency information.
