Abstract

An operational mechanism enables extending the range of cognitive networks through the use of repeater transceivers and selective routing.

Claims

1. On a wireless radio network comprising a plurality of transceivers of which at least one transceiver is a base station and at least one transceiver is configured as a simplex repeater, a method of repeating wireless messages comprising the steps of:

(a) said simplex repeater waiting for an incoming message;

(b) said simplex repeater receiving an incoming message;

(c) determining whether the source of said message is a base station;

(d) if said source is a base station, determining whether said message is a broadcast message or has a destination address found in a repeat list of addresses, and if said message is a broadcast message or has an address found in said repeat list, repeating said message and returning to step (a), and otherwise, returning to step (a) without repeating said message;

(e) and if said source is not a base station, determining whether said destination address of said message is found in said repeat list, and if said message has an address found in said repeat list, returning to step (a) without repeating said message, and otherwise, repeating said message and returning to step (a).

2. The method of claim 1 wherein said transceivers are cognitive radios.

3. The method of claim 1 wherein said plurality of transceivers comprises one or more far remote transceivers located outside the coverage area of said base station and within the coverage area of said at least one simplex repeater, and said repeat list includes addresses of said far remote receivers.

4. The method of claim 3 wherein said message is an IP message.

5. The method of claim 3 wherein said message is a SCADA message.

6. The method of claim 2 wherein cognitive network information is exchanged between said far remote transceivers and said simplex repeater.

7. On one or more wireless radio networks comprising a plurality of transceivers of which one transceiver is a first base station, one transceiver is a second base station, and at least one transceiver is configured as a duplex repeater connected to said second base station, a method of repeating wireless messages comprising the steps of:

(a) said duplex repeater receiving and maintaining a routing table provided by said second base station;

(b) said duplex repeater waiting for an incoming message;

(c) said duplex repeater receiving an incoming message;

(d) determining whether the source of said message is said first base station;

(e) if said source is said first base station, determining whether said message is a broadcast message or has a destination address found in said routing table, and if said message is a broadcast message or has an address found in said routing table, sending said message to said second base station and returning to step (b), and otherwise, returning to step (b) without sending said message to said second base station;

(e) and if said source is not said first base station, determining whether said destination address of said message is found in said routing table, and if said message has an address found in said routing table, returning to step (b) without repeating said message, and if said destination of said message is not found in said routing table, repeating said message and returning to step (b).

8. The method of claim 7 wherein said transceivers are cognitive radios.

9. The method of claim 7 wherein said one or more wireless radio networks further comprises at least first and second independent wireless radio networks, said first network being controlled by said first base station and having a first plurality of remote transceivers, said second network being controlled by said second base station and having a second plurality of remote transceivers, and said routing table including the addresses of said second plurality of remote transceivers.

10. The method of claim 9 wherein said message is an IP message.

11. The method of claim 9 wherein said message is a SCADA message.

12. The method of claim 9 wherein cognitive network information is exchanged between said first and second networks.

13. A wireless radio network comprising:

a plurality of transceivers of which at least one transceiver is a base station,

at least one transceiver configured as a simplex repeater,

and one or more transceivers are far remote transceivers located outside the coverage area of said base station and within the coverage area of said simplex repeater,

said configuration of said simplex repeater causing said simplex receiver to receive an incoming message; and

if the source of said message is said base station and said message is a broadcast message, to repeat said message; and

if the source of said message is said base station and said message is not a broadcast message, to determine whether the destination address of said message is listed in a repeat list of addresses maintained by said simplex repeater; and

if said address is listed in said repeat list, to repeat said message; and

if said address is not listed in said repeat list, to discard said message;

and if said source is not said base station, to determine whether said destination address of said message is listed in a repeat list of addresses maintained by said simplex repeater, and if said address is listed in said repeat list, to discard said message; and

if said address is not listed in said repeat list, to repeat said message.

14. The wireless radio network of claim 13 wherein said transceivers are cognitive radios.

15. The wireless radio network of claim 14 wherein said repeat list comprises addresses of far remote transceivers located outside the coverage area of said base station and within the coverage area of said simplex repeater.

16. The wireless radio network radio of claim 15 wherein said message is an IP message.

17. The wireless radio network of claim 15 wherein said message is a SCADA message.

18. The wireless radio network of claim 14 wherein cognitive network information is exchanged between said far remote transceivers and said simplex repeater.

19. A wireless radio network comprising:

first and second wireless subnetworks, each said subnetwork comprising a plurality of transceivers,

said first subnetwork comprising a first base station and at least one transceiver configured as a duplex repeater,

said second subnetwork comprising a second base station and one or more remote transceivers, said second base station being in electronic communication with said duplex repeater and providing said duplex repeater with a routing table;

said configuration of said duplex repeater causing said duplex repeater to receive an incoming message; and

if the source of said message is said first base station and said message is a broadcast message, to repeat said message; and

if the source of said message is said first base station and said message is not a broadcast message, to determine whether the destination address of said message is found in said routing table, and if said address is found in said routing table, to repeat said message; and

if said address is not listed in said routing table, to discard said message;

and if said source is not said first base station, to determine whether said destination address of said message is listed in said routing table, and if said address is not listed in said routing table, to repeat said message; and

if said address is listed in said routing table, to discard said message.

20. The wireless radio network of claim 19 wherein said transceivers are cognitive radios.

21. The wireless radio network of claim 20 wherein said routing table comprises addresses of remote transceivers within said second subnetwork.

22. The wireless radio network of claim 21 wherein said message is an IP message.

23. The wireless radio network of claim 21 wherein said message is a SCADA message.

24. The wireless radio network of claim 21 wherein cognitive network information is exchanged between said first and second subnetworks.
