System and method for selecting repeaters
A method is described for selecting repeaters comprising: transmitting a first signal from a first node to a second node; measuring signal strength of the first signal at the second node; transmitting a second signal from the second node to the first node; measuring signal strength of the second signal at the first node; and selecting the second node as a repeater based on the signal strength of the first signal and/or the signal strength of the second signal. Another embodiment of the method comprises: calculating signal strength of a signal transmitted to each of a plurality of nodes (the signal strength being measured at each node of the plurality); and selecting one or more of the nodes to be a repeater if the signal strength is below a maximum threshold value and above a minimum threshold value.
1. A method for selecting repeaters comprising:
transmitting a first signal from a first node to a second node;
measuring signal strength of said first signal at said second node;
transmitting a second signal from said second node to said first node, said signal strength of said first signal stored as data in said second signal;
measuring signal strength of said second signal at said first node; and
selecting said second node as a repeater based on said signal strength of said first signal and/or said signal strength of said second signal.
2. The method of claim 1 further comprising:
selecting said second node as a repeater if said signal strength of said first signal is within a specified range and said signal strength of said second signal is within a specified range.
3. The method as in claim 1 further comprising:
selecting said second node as a repeater if combined signal strength of said first signal and said second signal is within a specified range.
4. The method as in claim 1 further comprising:
selecting said second node as a repeater if an average of said signal strength of said first signal and said signal strength of said second signal is within a specified range.
5. The method as in claim 1 wherein said first node performs selecting of said second node as a repeater based on said signal strength of said first signal and/or said signal strength of said second signal.
6. The method as in claim 1 further comprising:
if said second node is selected as a repeater, transmitting a third signal from said second node to a third node;
measuring signal strength of said third signal at said third node;
transmitting a fourth signal from said third node to said second node;
measuring signal strength of said fourth signal at said second node; and
selecting said third node as a second-tier repeater based on said signal strength of said third signal and/or said signal strength of said fourth signal.
7. The method of claim 1 further comprising:
selecting said third node as a second-tier repeater if said signal strength of said first signal is within a specified range and said signal strength of said second signal is within a specified range.
8. An article of manufacture including a sequence of instructions which, when executed by a processor of a first network node, cause said processor to:
transmit a first signal from said first network node to a second node;
measure signal strength of said first signal at said second node;
transmit a second signal from said second node to said first node, said signal strength of said first signal is stored as data in said second signal;
measure signal strength of said second signal at said first node; and
select said second node as a repeater based on said signal strength of said first signal and/or said signal strength of said second signal.
9. The article of manufacture as in claim 8 including additional instructions which, when executed by said processor, cause said processor to:
select said second node as a repeater if said signal strength of said first signal is within a specified range and said signal strength of said second signal is within a specified range.
10. The article of manufacture as in claim 8 including additional instructions which, when executed by said processor, cause said processor to:
select said second node as a repeater if combined signal strength of said first signal and said second signal is within a specified range.
11. The article of manufacture as in claim 8 including additional instructions which, when executed by a processor, cause said processor to:
select said second node as a repeater if an average of said signal strength of said first signal and said signal strength of said second signal is within a specified range.
12. The article of manufacture as in claim 8 wherein said first node performs selecting of said second node as a repeater based on said signal strength of said first signal and/or said signal strength of said second signal.
13. The article of manufacture as in claim 8 including additional instructions which, when executed by a processor, cause said processor to:
if said second node is selected as a repeater, transmit a third signal from said second node to a third node;
measure signal strength of said third signal at said third node;
transmit a fourth signal from said third node to said second node;
measure signal strength of said fourth signal at said second node; and
select said third node as a second-tier repeater based on said signal strength of said third signal and/or said signal strength of said fourth signal.
