Abstract

A wireless connection system and method are provided to connect diverse Ad-hoc network groups. A first Ad-hoc network group has a first network node and a first edge node wirelessly connecting with each other. The second Ad-hoc network group has a second network node and a second edge node wirelessly connecting with each other without connecting the first Ad-hoc network group. The first and second edge nodes have multiple wireless modules respectively. One of the wireless modules is used to connect wireless with other network nodes in the same Ad-hoc network group. The rest extra wireless module(s) is used to connect wirelessly with another extra wireless module(s) of the edge node(s) in different Ad-hoc network group(s). Therefore, the independent first and second Ad-hoc network groups are now capable of wirelessly connecting with each other.

Claims

1. A wireless connection system, comprising:

at least one first network node and at least one first edge node each having a first wireless module equipped therein, each of the first network node and the first edge node wirelessly connecting with each other through the first wireless modules so as to form a first Ad-hoc network group;

at least one second network node and at least one second edge node each having a second wireless module, each of the second network node and the second edge node wirelessly connecting with each other through the second wireless modules so as to form a second Ad-hoc network group without wirelessly connecting with the first Ad-hoc network group through the first and second wireless modules;

wherein the first edge node has a first extra wireless module and the second edge node has a second extra wireless module, the first edge node and the second edge node connecting with each other through the first and second extra wireless modules so that the first Ad-hoc network group and the second Ad-hoc network group wirelessly connect with each other through the first edge node and the second edge node; and

at least one joint network information sheet, recording joint network information of the wireless-connected first and second Ad-hoc network groups and being stored in the first Ad-hoc network group or the second Ad-hoc network group.

2. The wireless connection system of claim 1, wherein the joint network information sheet is respectively stored in each of the first network node, the first edge node, the second network node and the second edge node.

3. The wireless connection system of claim 1, wherein the joint network information sheet is respectively stored in each of the first edge node and the second edge node.

4. The wireless connection system of claim 1 further comprising an update module, upon wireless connection of the first and second Ad-hoc network groups, the update module updating first network information sheet of the first Ad-hoc network group and second network information sheet of the second Ad-hoc network group into the joint network information sheet with the joint network information.

5. A wireless connection method, comprising the steps of:

enabling at least one first network node, at least one first edge node, at least one second network node and at least one second edge node;

through at least one first wireless module equipped in each of the first network node and the first edge node, wirelessly connecting the first edge node and the first network node so as to form a first Ad-hoc network group, and through at least one second wireless module equipped in each of the second network node and the second edge node, wirelessly connecting the second edge node and the second network node so as to form a second Ad-hoc network group without wirelessly connecting the first Ad-hoc network group through the first and second wireless modules;

enabling a first extra wireless module equipped in the first edge node and enabling a second extra wireless module equipped in the second edge node;

wirelessly connecting the first edge node and the second edge node through the first and second extra wireless modules, so that the first Ad-hoc network group and the second Ad-hoc network group wirelessly connect with each other through the first edge node and the second edge node; and

respectively recording network information of each of the first edge node and the second edge node into a joint network information sheet of the first edge node and/or the second edge node.

6. The wireless connection method of claim 5, wherein the joint network information sheet is stored respectively in each of the first network node, the first edge node, the second network node and the second edge node.

7. The wireless connection method of claim 5, wherein the joint network information sheet is respectively stored in each of the first edge node and the second edge node.

8. The wireless connection method of claim 5 further comprising a step of:

updating the joint network information recorded in the network information sheet after the first Ad-hoc network group and the second Ad-hoc network group being wirelessly connected.
