1. A method for adaptive power setting of a first wireless device in an ad-hoc wireless network comprising the steps of:

  • initially operating said first wireless device at a first transmission power level, said first transmission power level being selected at a level not expected to facilitate a connection between said first wireless device and additional wireless devices;

    increasing the transmission power level, up to a predetermined maximum power level, while incrementally connecting with additional wireless devices; and

    terminating said step of increasing the transmission power level, and operating said first wireless device at a current transmission power level, if connection with a particular one of said additional wireless device causes a connectivity constraint to be satisfied, wherein said connectivity constraint is a geometric connectivity constraint, said geometric connectivity constraint is based on an angular distribution between said connected additional wireless devices such that said connectivity constraint is satisfied when said angular distribution is less than or equal to one hundred eight degrees (180°

    ).
