1. In a multiple node network having a data collection node at a first end and a data transmission node at a second end, a method for selecting the directionality of transmission and reception at one of said nodes to maximize combined information throughput at said data collection end, comprising:

  • determining a throughput metric for each directional choice based on combined end to end throughput of information for said directional choice; and

    selecting directionality according to said throughput metric to maximize end to end throughput between said first end and said second end;

    wherein said throughput metric is based on measurement of latency;

    wherein said latency is attributable to busy-ness and includes summing simple link throughput times from least busy to busiest with a weighting based on said busy-ness; and

    wherein weighted throughput WT is determined as follows;

    WTa=

    i=1N






    ((1-Bi)*LTia*(

    k=1i-1






    Bk
    )
    )
    ,
    embedded imagewhere;

    Bi is the busy-ness measure defined as the ratio of transmission time to the listening time plus the transmission time, for the ith node at the end of each link;

    LTia is the simple link throughput for the ith node for a particular directionality element a; and

    WTa is the weighted throughput for the directionality element a.
