Abstract

Systems and methods for reducing congestion in a wireless communication network are provided. In one aspect, an improved MAC layer protocol is provided that allows channel switching for data communications over a wireless network on a frame by frame basis allowing increased use of spectrum and significantly reducing congestion. Additionally, throughput is increased and battery life is conserved by reducing the power level for an RTS message to the minimum power needed to reach the recipient node. The corresponding CTS message is then sent by the recipient node and the range of the CTS message is sufficient to inform other nodes in the network that the recipient is not available for communication. This method allows other nodes in the network to remain free to communicate with each other. Moreover, the minimum power level needed to send an RTS message to each node may be maintained in a local routing table or other data storage area on the wireless communication device.

Claims

1. A system for high bandwidth throughput in a wireless communication network, comprising:

a wireless mesh network;

a plurality of network device communicatively coupled to the mesh network, wherein each network device is configured to communicate with at least one other network device via the wireless mesh network;

wherein inter-device data communication implements a high bandwidth computer executed application.

2. The system of claim 1, wherein the application is a multi-player video game.

3. The system of claim 2, wherein the inter-device data communication comprises audio data related to the video game.

4. The system of claim 1, wherein the inter-device data communication comprises voice data originating from a user of a network device.

5. A system for radio frequency identification, comprising:

an ad hoc wireless mesh network;

a plurality of radio frequency identification modules, each module attached to a predetermined item and configured to communicate with at least one other module over the ad hoc wireless mesh network;

wherein data communication between the modules over the ad hoc wireless mesh network provides status information related to each predetermined item.

7. The system of claim 7, wherein the status information comprises logistics information

6. The system of claim 7, wherein the status information comprises location information

8. The system of claim 7, wherein the status information comprises position information

9. The system of claim 7, wherein the status information comprises supply chain management information.

10. A system for modifying the physical domain of an ad hoc wireless mesh network, comprising:

an access point configured to bridge traffic from an ad hoc wireless mesh network to another network;

a plurality of repeater points, each repeater point adaptable to receive power from a standard power source, each repeater further configured to route data communication traffic on the ad hoc wireless mesh network to the access point or one of the plurality of repeater points, said data communication traffic including radio signal receive power information, number of repeater points between a repeater point and the access point, best rout performance, and real-time performance metrics; and

a plurality of network devices, each network device configured for data communication over the ad hoc wireless mesh network, wherein the physical domain of the ad hoc wireless mesh network is modified by placing an additional repeater point within wireless communication range of the access point or one of the plurality of repeater points.
