Abstract

A MANET may include a plurality of MANET nodes each including a wireless transceiver, a position determining device, and a controller cooperating with the wireless transceiver and position determining device for establishing a wireless communication link with an adjacent MANET node based upon a time division multiple access (TDMA) implementation. The TDMA implementation may use time slots without using a range dependent guard time therein. The controller may further determine a range to the adjacent MANET node, and schedule time slots to offset a link delay in a received signal from the adjacent MANET node based upon the determined range.

Claims (35)

1. A mobile ad-hoc network (MANET) comprising;

a plurality of MANET nodes each comprising a wireless transceiver, a position determining device, and a controller cooperating with said wireless transceiver and position determining device and configured to

establish a wireless communication link with an adjacent MANET node based upon a time division multiple access (TDMA) implementation,

the TDMA implementation using time slots and without using a range dependent guard time therein,

determine a range and an angle to said adjacent MANET node, and

schedule time slots to offset a link delay in a received signal from said adjacent MANET node based upon the determined range and the determined angle.

2. The MANET of claim 1 wherein each MANET node further comprises an antenna coupled to said wireless transceiver.

3. The MANET of claim 2 wherein said antenna comprises a directional antenna; and wherein said controller is configured to establish a directional wireless communication link with said adjacent MANET node.

4. The MANET of claim 1 wherein the TDMA implementation comprises a distributed TDMA implementation wherein time slot scheduling operations are shared between said MANET nodes.

5. The MANET of claim 1 wherein the TDMA implementation comprises a variable-length time slot TDMA implementation.

6. The MANET of claim 1 wherein said controller is further configured to cooperate with at least one neighboring MANET node when scheduling time slots to reduce a likelihood of interference.

7. The MANET of claim 1 wherein said controller is configured to separately schedule transmit and receive time slots.

8. The MANET of claim 1 wherein said MANET nodes are configured to exchange respective positions with neighboring MANET nodes.

9. A mobile ad-hoc network (MANET) node comprising:

a wireless transceiver;

a position determining device; and

a controller cooperating with said wireless transceiver and position determining device and configured to

establish a wireless communication link with an adjacent MANET node based upon a time division multiple access (TDMA) implementation,

the TDMA implementation using time slots and without using a range dependent guard time therein,

determine a range and an angle to the adjacent MANET node, and

schedule time slots to offset a link delay in a received signal from the adjacent MANET node based upon the determined range and the determined angle.

10. The MANET node of claim 9 further comprising a directional antenna coupled to said wireless transceiver; and wherein said controller is configured to establish a directional wireless communication link with the adjacent MANET node.

11. The MANET node of claim 9 wherein the TDMA implementation comprises a distributed TDMA implementation wherein time slot scheduling operations are shared with the adjacent MANET node.

12. The MANET node of claim 9 wherein the TDMA implementation comprises a variable-length time slot TDMA implementation.

13. The MANET node of claim 9 wherein said controller is further configured to cooperate with at least one neighboring MANET node when scheduling time slots to reduce a likelihood of interference.

14. The MANET node of claim 9 wherein said controller is configured to separately transmit and receive time slots.

15. A mobile ad-hoc network (MANET) communications method for a plurality of MANET nodes comprising:

establishing a wireless communication link between a pair of adjacent MANET nodes based upon a time division multiple access (TDMA) implementation;

the TDMA implementation using time slots and without using a range dependent guard time therein;

determining a range and an angle between the pair of adjacent MANET nodes; and

scheduling time slots to offset a link delay in received signals between the pair of adjacent MANET nodes based upon the determined range and the determined angle.

16. The method of claim 15 wherein each MANET node further comprises a directional antenna; and wherein establishing comprises establishing a directional wireless communication link between the pair of adjacent MANET nodes.

17. The method of claim 15 wherein the TDMA implementation comprises a distributed TDMA implementation wherein time slot scheduling operations are shared between the MANET nodes.

18. The method of claim 15 wherein the TDMA implementation comprises a variable-length time slot TDMA implementation.

19. The method of claim 15 wherein the controller further cooperates with at least one neighboring MANET node when scheduling time slots to reduce a likelihood of interference.
