Abstract

A method and system for utilizing smart antenna in transmission of messages between nodes (102a-102n) are disclosed. A wireless communication system includes a plurality of nodes (102a-102n), and each node is capable of being connected to each other node. At least a portion of the nodes are provided with a smart antenna (204) configured to generate a plurality of directional beams (109a-109h). Each node maintains a list of other nodes and beam configuration information to be used in transmission of messages to other nodes. When a source node is required to transmit to a target node, the source node retrieves the beam configuration information and transmits with a directional beam (109) directed to the target node.

Claims (17)

1. A wireless communication system comprising a plurality of nodes, each node being connected to at least one neighbor node, each node comprising:

a smart antenna for generating a plurality of directional beams;
a memory for storing a list of neighbor nodes having connections and beam configuration information to be used in transmission of messages to the neighbor nodes;
a controller for selecting a particular directional beam for transmitting a particular message to another node while independently controlling each of said plurality of directional beams.
2. The system of claim 1 wherein said controller obtains information regarding traffic load condition and capabilities of neighbor nodes and selects proper paths for transmitting messages to another node based on the information.
3. The system of claim 1 wherein the plurality of nodes comprise a mesh network.
4. The system of claim 1 wherein the plurality of nodes comprise a cellular network.
5. The system of claim 1 wherein one node among the plurality of nodes is designated as a controlling node, and said controlling node collects information regarding traffic load condition and capabilities of each node and controls path determination in each node.
6. The system of claim 1 wherein each node transmits beacon signals carrying a beacon message to neighbor nodes, and each node utilizes the beacon message in selecting a proper path for transmitting messages to other nodes.
7. The system of claim 6 wherein the beacon message includes a power level, a traffic level, a interference level, a priority of access, security, identification, and other access control and security control information.
8. The system of claim 1 wherein each node is connected using more than one beam whereby a beam is adaptively switched between the provided beams for the connection.
9. A method for utilizing smart antennas in a wireless communication system comprising a plurality of nodes, at least two of the plurality of nodes each having a smart antenna which generates at least one directional beam for connection to at least one neighbor node, the method comprising:
measuring and storing a list of neighbor nodes having connections and beam direction and configuration information to be used in transmission of messages to the neighbor nodes;
generating a directional beam for transmitting a particular message to a target node in accordance with the beam direction and configuration information;
and transmitting the message to the target node with the generated directional beam.
10. The method of claim 9 further comprising the step of updating the list reflecting a change or modification of the network.
11. The method of claim 9 further comprising the step of obtaining information regarding traffic load condition and capabilities of neighbor nodes and selecting proper paths for transmitting the message to another node based on the information.
12. The method of claim 9 wherein the plurality of nodes comprise a mesh network.
13. The method of claim 9 wherein the plurality of nodes comprise a cellular network.
14. The method of claim 9 wherein one node among the plurality of nodes is designated as a controlling node, and the controlling node collects information regarding traffic load condition and capabilities of each node and controls path determination in each node.
15. The method of claim 9 wherein each node transmits beacon signals carrying a beacon message to neighbor nodes, and each node utilizes the beacon message in selecting a proper path for transmitting messages to other nodes.
16. The method of claim 15 wherein the beacon message includes a power level, a traffic level, a interference level, a priority of access, security, identification, and other access control and security control information.
17. The method of claim 9 wherein each node is connected using more than one beam, whereby a beam is adaptively switched between the provided beams for the connection.
