Abstract

A method directed to overhearing problems of Body Area Network (BAN) medium access control protocols. The method comprises generating a preamble frame (S310); encoding a destination address of a target receiver device as a length of the preamble frame (S320); and transmitting the preamble frame (S330).

Claims

1. A computer-implemented method (300), comprising:

generating a preamble frame (S310);

encoding a destination address of a target receiver device as a length of the preamble frame (S320); and

transmitting the preamble frame (S330).

2. The method of claim 1, further comprising selecting a frequency channel for transmitting the preamble frame, wherein the frequency channel is being determined based on the destination address.

3. The method of claim 1, wherein encoding the destination address further comprises summing a smallest length frame that can be reliably detected by a receiver device and a decimal value of the destination address.

4. The method of claim 1, wherein encoding the destination address further comprises summing a smallest length frame that can be reliably detected by a receiver device and a value computed by a hash function, wherein the destination address is an input key of the hash function.

5. The method of claim 2, wherein selecting the frequency channel further comprises applying a hash function to map the destination address to an identification (ID) number of a logical channel.

6. The method of claim 1, wherein the destination address is at least a medium access control (MAC) address utilized in a body area network (BAN).

7. The method of claim 1, further comprising encoding multiple levels of information as the length of the preamble frame.

8. The method of claim 7, wherein the encoded preamble frame comprises multiple parts, the length of each part being encoded to represent a specific type of information.

9. A computer-implemented method, comprising:

generating a wake-up signal;

encoding a destination address of a target receiver device as duration of the wake-up signal; and

transmitting the wake-up signal.

10. The method of claim 9, further comprising selecting a frequency channel for transmitting the wake-up signal, wherein the frequency channel is determined based on the destination address.

11. The method of claim 9, wherein encoding the destination address further comprises summing a smallest duration of the wake-up signal that can be reliably detected by a receiver device and a decimal value of the destination address.

12. The method of claim 9, wherein encoding the destination address further comprises summing a smallest duration of the wake-up signal that can be reliably detected by a receiver device and a value computed by a hash function, wherein the destination address is an input key of the hash function.

13. The method of claim 9, wherein the destination address is at least a medium access control (MAC) address utilized in at a least a body area network (BAN).

14. The method of claim 9, further comprising encoding multiple levels of information as the duration of the wake-up signal.

15. The method of claim 14, wherein the encoded wake-up signal comprises multiple parts, the length of each part being encoded to represent a specific type of information.
