Abstract

A network system includes a plurality of network groups. Each of the network groups includes at least one node. The at least one node is configured for transmitting a beacon response according to a beacon request transmitted by a new node. When the at least one node of the at least one of the network groups transmits the beacon response, at least another one of the network groups is in a sleep state, and the new node connects with the at least one node of the at least one of the network groups according to the beacon response. A connection method of the network system is also disclosed herein.

Claims

1. A network system comprising:

a plurality of network groups, each of the network groups comprising at least one node, the at least one node being configured for transmitting a beacon response according to a beacon request transmitted by a new node;

wherein when the at least one node of at least one of the network groups transmits the beacon response, at least another one of the network groups is in a sleep state, and the new node connects with the at least one node of the at least one of the network groups according to the beacon response.

2. The network system of claim 1, further comprising:

a coordinator configured for sending a sleep broadcast so as to inform the at least another one of the network groups of entering the sleep state.

3. The network system of claim 2, wherein when a number of the at least one node of any of the network groups reaches a predetermined value, the coordinator sends the sleep broadcast.

4. The network system of claim 3, wherein the predetermined value is substantially equal to a greatest number of nodes that can be accommodated by each of the network groups.

5. The network system of claim 1, wherein the network groups take turns being in the sleep state.

6. The network system of claim 1, wherein a duration of the sleep state is determined based on a plurality of application ends corresponding to the network groups or a number of the network groups.

7. The network system of claim 6, wherein the network system comprises a plurality of network groups in the sleep state, the durations of the network groups in the sleep state are different from each other.

8. A connection method of a network system comprising:

transmitting a beacon request by a new node;

at least one node of at least one of a plurality of network groups transmitting a beacon response according to the beacon request, and at least another one of the network groups being in a sleep state; and

connecting with the at least one node of the at least one of the network groups according to the beacon response by the new node.

9. The connection method of claim 8, further comprising:

sending a sleep broadcast to inform the at least another one of the network groups of entering the sleep state by a coordinator.

10. The connection method of claim 9, further comprising:

determining whether the at least another one of the network groups is necessary to enter the sleep state; and

sending the sleep broadcast by the coordinator if the at least another one of the network groups is necessary to enter the sleep state.

11. The connection method of claim 10, wherein the step of determining whether the at least another one of the network groups is necessary to enter the sleep state further comprises:

determining whether a number of the at least one node of any of the network groups reaches a predetermined value.

12. The connection method of claim 11, wherein the predetermined value is substantially equal to a greatest number of the nodes that can be accommodated by each of the network groups.

13. The connection method of claim 8, further comprising the network groups taking turns to be in the sleep state.

14. The connection method of claim 8, wherein a duration of the sleep state is determined based on a plurality of application ends corresponding to the network groups or a number of the network groups.

15. The connection method of claim 14, wherein the network system comprises a plurality of network groups in the sleep state, durations of the network groups in the sleep state are different from each other.

16. A network system comprising:

a plurality of nodes, at least one of the nodes being configured for transmitting a beacon response according to a beacon request transmitted by a new node;

wherein, when the at least one of the nodes transmits the beacon response, at least another one of the nodes is in a sleep state, and the new node connects with the at least one of the nodes according to the beacon response.

17. The network system of claim 16, further comprising:

a coordinator configured for sending a sleep broadcast so as to inform the at least another one of the nodes of entering the sleep state.

18. The network system of claim 17, wherein when a number of the nodes reaches a predetermined value, the coordinator sends the sleep broadcast.

19. The network system of claim 18, wherein the predetermined value is substantially equal to a greatest number of the beacon responses that can be received by the new node.

20. The network system of claim 16, wherein the nodes take turns being in the sleep state.

21. The network system of claim 16, wherein a duration of the sleep state is determined based on a plurality of application ends corresponding to the nodes or a number of the nodes.

22. The network system of claim 21, wherein the network system comprises a plurality of nodes in the sleep state, the durations of the nodes in the sleep state are different from each other.

23. A connection method of a network system comprising:

transmitting a beacon request by a new node;

at least one of a plurality of nodes transmitting a beacon response according to the beacon request, and at least another one of the nodes being in a sleep state; and

connecting with the at least one of a plurality of nodes according to the beacon response by the new node.

24. The connection method of claim 23, further comprising:

sending a sleep broadcast to inform the at least another one of the nodes of entering the sleep state by a coordinator.

25. The connection method of claim 24, further comprising:

determining whether the at least another one of the nodes is necessary to enter the sleep state; and

sending the sleep broadcast by the coordinator if the at least another one of the nodes is necessary to enter the sleep state.

26. The connection method of claim 25, wherein the step of determining whether the at least another one of the nodes is necessary to enter the sleep state further comprises:

determining whether a number of the nodes reaches a predetermined value.

27. The connection method of claim 26, wherein the predetermined value is substantially equal to a greatest number of the beacon responses that can be received by the new node.

28. The connection method of claim 23, wherein the nodes take turns to be in the sleep state.

29. The connection method of claim 23, wherein a duration of the sleep state is determined based on a plurality of application ends corresponding to the nodes or a number of the nodes.

30. The connection method of claim 29, wherein the network system comprises a plurality of nodes in the sleep state, the durations in which the nodes in the sleep state are different from each other.
