Systems and methods for improved media access control

1. A method of medium access control comprising:

using, as the first integer, a nonce value, the nonce value being based on one or more of the following: a random integer, a pseudorandom integer, or a time value.

7. The method of claim 1 , further comprising:

using, as the first integer, a value that is a function of a nonce value.

8. The method of claim 1 , wherein receiving the first message comprises:

using, as the first message, a request to send message.

9. The method of claim 1 , wherein receiving the second message comprises:

using, as the second message, a clear to send message.

10. The method of claim 1 , further comprising:

using the first, second, third, and fourth messages as the medium access control of a wireless network.

11. The method of claim 1 , further comprising:

using, as the first message, a request-to-send message, the request-to-send message providing media access control.

12. A method of medium access control in a wireless network comprising:

receiving a request to send message, the request to send message including a first integer;

sending, in response to the received request to send message, a clear to send message including the first integer and a second integer;

receiving, in response to the clear to send message, a data message including the second integer, the second integer serving to authenticate the data message;

sending, in response to the received data message, an acknowledgement message including the first integer; and

using, as the first and second integers, the same value.

13. A system of medium access control in a wireless network comprising:

means for receiving a request to send message, the request to send message including a first integer;

means for sending, in response to the received request to send message, a clear to send message including the first integer and a second integer;

means for receiving, in response to the clear to send message, a data message including the second integer, the second integer serving to authenticate the data message; and

means for sending, in response to the received data message, an acknowledgement message including the first integer, wherein the same value is used for the first and second integers.

14. A system of medium access control comprising:

means for receiving a first message including a first integer;

means for sending a second message including a second integer, the second message sent in response to the first message;

means for receiving a third message, in response to the second message, including data and a third integer, the third integer serving to authenticate the third message; and

means for sending, in response to the third message, a fourth message including a fourth integer, the fourth message serving to acknowledge receipt of the third message, wherein the same value is used for the first, second, third, and fourth integers.

15. A system for medium access control, the system comprising:

a processor; and

a memory,

wherein the processor and the memory are configured to perform a method comprising:

receiving a first message including a first integer;

sending a second message including a second integer, the second message sent in response to the first message;

receiving, in response to the second message, a third message including data and a third integer, the third integer serving to authenticate the third message;

sending, in response to the third message, a fourth message including a fourth integer, the fourth message serving to acknowledge receipt of the third message;

using, as the first, second, third, and fourth integers, the same value.

16. The system of claim 15 , further comprising:

using, as the same value, a random integer.

17. The system of claim 15 , further comprising:

using, as the same value, a pseudorandom integer.

18. The system of claim 15 , further comprising:

using, as the same value, a time value.

19. The system of claim 15 , further comprising:

using, as the same value, a time value based on a Global Positioning System (GPS).

20. The system of claim 15 , further comprising:

using, as the first integer, a nonce value, the nonce value being based on one or more of the following: a random integer, a pseudorandom integer, or a time value.

21. A system for medium access control in a wireless network,

the system comprising:

a processor; and

a memory,

wherein the processor and the memory are configured to perform a method comprising:

receiving a request to send message, the request to send message including a first integer;

sending, in response to the received request to send message, a clear to send message including the first integer and a second integer;

receiving, in response to the clear to send message, a data message including the second integer, the second integer serving to authenticate the data message; and

sending, in response to the received data message, an acknowledgement message including the first integer, wherein the same value is used for the first and second integers.

22. A computer-readable storage medium containing instructions which, when executed on a data processor, cause the data processor to perform a method of medium access control, the method comprising:

receiving a first message including a first integer;

sending a second message including a second integer, the second message sent in response to the first message;

receiving, in response to the second message, a third message including data and a third integer, the third integer serving to authenticate the third message;
