Abstract

A mobile ad hoc network (MANET) may include a plurality of mobile nodes. Each mobile node may include a wireless transceiver and a controller cooperating therewith for exchanging isosynchronous Internet Protocol (IP) communications with at least one adjacent mobile node. The isosynchronous IP communications may comprise at least one of voice communications and data communications.

Claims

1. A mobile ad hoc network (MANET) comprising:

a plurality of mobile nodes;

each mobile node comprising a wireless transceiver and a controller cooperating therewith for exchanging isosynchronous Internet Protocol (IP) communications with at least one adjacent mobile node.

2. The MANET according to claim 1 wherein said wireless transceiver and controller further cooperate to transmit a connection message for registering with the at least one adjacent mobile node and to enter an active communication mode upon completion of the registering.

3. The MANET according to claim 2 wherein said wireless transceiver and controller further cooperate to periodically transmit a keepalive message to the at least one adjacent mobile node.

4. The MANET according to claim 3 wherein said controller stores a list of other adjacent mobile nodes in the active communication mode based upon the completion of registering and the keepalive message.

5. The MANET according to claim 4 wherein said wireless transceiver and controller of at least one of said plurality of mobile nodes further cooperate to enter a low power consumption mode when the keepalive message is not received during a set period of time.

6. The MANET according to claim 1 wherein said plurality of mobile nodes comprises a source node, a destination node, and at least one intermediate node therebetween;

wherein said source node transmits a transmission request message by way of said at least one intermediate node to said destination node; and

wherein said destination node initializes the isosynchronous IP communications with said source node by way of said at least one intermediate node based upon receipt of the transmission request message.

7. The MANET according to claim 6 wherein at least one of said source and destination nodes sends a transmission end message by way of said at least one intermediate node to end the isosynchronous IP communications.

8. The MANET according to claim 1 wherein said controller comprises a real time communications (RTC) subprocessor.

9. The MANET according to claim 1 wherein said controller comprises a voice compression codec subprocessor.

10. The MANET according to claim 1 wherein the isosynchronous IP communications comprise at least one of voice communications and data communications.

11. A mobile node for a mobile ad hoc network (MANET) comprising:

a wireless transceiver; and

a controller cooperating with said wireless transceiver for exchanging isosynchronous Internet Protocol (IP) communications with at least one adjacent mobile node.

12. The mobile node according to claim 11 wherein said wireless transceiver and controller further cooperate to transmit a connection message for registering with the at least one adjacent mobile node and to enter an active communication mode upon completion of the registering.

13. The mobile node according to claim 12 wherein said wireless transceiver and controller further cooperate to periodically transmit a keepalive message to the at least one adjacent mobile node.

14. The mobile node according to claim 13 wherein said controller stores a list of other adjacent mobile nodes in the active communication mode based upon the completion of registering and the keepalive message.

15. A method for operating a mobile node in a mobile ad hoc network (MANET), the mobile node comprising a wireless transceiver, and a controller cooperating therewith, the method comprising:

exchanging isosynchronous Internet Protocol (IP) communications with at least one adjacent mobile node.

16. The method according to claim 15 further comprising:

transmitting a connection message for registering with the at least one adjacent mobile node; and

entering an active communication mode upon completion of the registering.

17. The method according to claim 16 further comprising:

periodically transmitting a keepalive message to the at least one adjacent mobile node.

18. The method according to claim 17 further comprising:

storing a list of other adjacent mobile nodes in the active communication mode based upon the completion of registering and the keepalive message.

19. The method according to claim 18 further comprising:

entering a low power consumption mode when the keepalive message is not received during a set period of time.

20. The method according to claim 15 wherein the MANET comprises a source node, a destination node, and at least one intermediate node therebetween;

and further comprising;

transmitting from the source node a transmission request message by way of the at least one intermediate node to the destination node; and

initializing the isosynchronous IP communications with the source node by way of the at least one intermediate node based upon receipt of the transmission request message.
