Abstract

Systems and methods for optimizing battery life in wireless multi-hop communication systems are provided. Some methods include a child node transmitting a data packet to a parent node in a wireless system, wherein the data packet includes a parent node identifier, data information, and a length of the data information, and wherein the data packet omits inclusion of a child node identifier. Some methods include a parent node receiving a data packet from a child node in a wireless system, wherein the data packet includes a parent node identifier, data information, and a length of the data information, and wherein the data packet omits inclusion of a child node identifier.

Claims

1. A method comprising:

a child node transmitting a first data packet to a first parent node in a wireless system; and

the first parent node transmitting a second data packet to a second parent node in the wireless system,

wherein the second parent node is a parent node of the first parent node,

wherein the first data packet includes a first identifier identifying the first parent node, first data information, and a first length of the first data information,

wherein the child node identifies itself to the first parent node based on a first assigned time slot during which the first data packet is transmitted, but the first data packet omits inclusion of a child node identifier,

wherein the second data packet includes a second identifier identifying the second parent node, the child node identifier, the first data information, and the first length of the first data information, and

wherein the first parent node identifies itself to the second parent node based on a second assigned time slot during which the second data packet is transmitted, but the second data packet omits inclusion of the first identifier identifying the first parent node.

2. The method of claim 1 further comprising:

the first parent node inserting the child node identifier into the second data packet.

3. The method of claim 2 wherein the first parent node inserting the child node identifier into the second data packet includes the first parent node inserting the child node identifier directly into the second data packet.

4. The method of claim 2 wherein the first parent node inserting the child node identifier into the second data packet includes the first parent node inserting the child node identifier into a position of the child node in a bitmap in the second data packet.

5. The method of claim 1 further comprising:

the first parent node inserting second data information and a second length of the second data information into the second data packet.

6. The method of claim 1 wherein the child node is at least one of a source node, a repeater node, and a repeater/source node.

7. The method of claim 1 wherein the first parent node is at least one of a source node, a repeater node, and a repeater/source node.

8. A method comprising:

a first parent node receiving a first data packet from a child node in a wireless system; and

a second parent node receiving a second data packet from the first parent node in the wireless system,

wherein the second node is a parent node of the first parent node,

wherein the first data packet includes a first identifier identifying the first parent node, first data information, and a first length of the first data information,

wherein the first parent node identifies the child node based on a first assigned time slot during which the first data packet is transmitted, but the first data packet omits inclusion of a child node identifier,

wherein the second data packet includes a second identifier identifying the second parent node, the child node identifier, the first data information, and the first length of the first data information, and

wherein the second parent node identifies the first parent node based on a second assigned time slot during which the second data packet is transmitted, but the second data packet omits inclusion of the first identifier identifying the first parent node.

9. The method of claim 8 further comprising:

the first parent node inserting the child node identifier into the second data packet.

10. The method of claim 9 wherein the first parent node inserting the child node identifier into the second data packet includes the first parent node inserting the child node identifier directly into the second data packet.

11. The method of claim 9 wherein the first parent node inserting the child node identifier into the second data packet includes the first parent node inserting the child node identifier into a position of the child node in a bitmap in the second data packet.

12. The method of claim 8 further comprising:

the first parent node inserting second data information and a second length of the second data information into the second data packet.

13. The method of claim 8 wherein the child node is at least one of a source node, a repeater node, and a repeater/source node.

14. The method of claim 8 wherein the first parent node is at least one of a source node, a repeater node, and a repeater/source node.
