1. A method of operating a first node of a wireless network comprising a plurality of nodes, the method comprising:

  • in the first node,maintaining, for a certain period of time, at least one adjustable radio frequency (RF) transmit power level corresponding to each node of a collection of nodes of the plurality of nodes;

    receiving a packet for transmission to a second node of the plurality of nodes;

    determining whether at least one adjustable RF transmit power level corresponding to the second node is maintained at the first node;

    wirelessly transmitting the received packet to the second node using a first RF transmit power level calculated from RF transmit power level information wirelessly shared with the first node via reports sent by one or more other nodes of the plurality of nodes, if the first node determines that at least one adjustable RF transmit power level corresponding to the second node is not maintained at the first node; and

    selecting a second RF transmit power level from the at least one adjustable RF transmit power level corresponding to the second node and wirelessly transmitting the received packet to the second node using the second RF transmit power level, if the first node determines that at least one adjustable RF transmit power level corresponding to the second node is maintained at the first node.
