Abstract
An apparatus and a method for routing data in a radio data communication system having one or more host computers, one or more intermediate base stations, and one or more RF terminals organizes the intermediate base stations into an optimal spanning-tree network to control the routing of data to and from the RF terminals and the host computer efficiently and dynamically. Communication between the host computer and the RF terminals is achieved by using the network of intermediate base stations to transmit the data.
Claims13
An RF multi-hop communication network comprising:
- a mobile communication node;
- a plurality of bridging nodes;
- and
- said bridging nodes dynamically arranging and rearranging communication pathways involving the mobile communication node based on the location of the mobile communication node in relation to the plurality of bridging nodes.
A multi-hop communication network comprising:
- a plurality of terminal nodes, ones of said plurality of terminal nodes comprising wireless mobile communication nodes;
- a plurality of bridging nodes, ones of said plurality of bridging nodes comprising wireless bridging nodes;
- a root node;
- said root node and said plurality of bridging nodes, together, forming a tree structure of communication pathways among said bridging nodes and said root node to support communication among said plurality of terminal nodes;
- said root node dynamically revising locally stored information regarding all of said plurality of terminal nodes that exist in a communication pathway away from said root node;
- and
- each of said plurality of bridging nodes dynamically revising locally stored information regarding all of said plurality of terminal nodes that exist in a communication pathway originating at said bridging node and terminating in a direction away from said root node.
A multi-hop communication network comprising:
- a plurality of terminal nodes, ones of said plurality of terminal nodes comprising wireless mobile communication nodes;
- a plurality of bridging nodes, ones of said plurality of bridging nodes comprising wireless bridging nodes;
- and
- said plurality of bridging nodes, together, forming a spanning tree to specify communication pathways among said plurality of terminal nodes.
A multi-hop communication network comprising:
- a plurality of terminal nodes, ones of said plurality of terminal nodes comprising wireless mobile communication nodes;
- a plurality of bridging nodes, ones of said plurality of bridging nodes comprising wireless bridging nodes;
- and
- said plurality of bridging nodes dynamically creating communication pathways among said bridging nodes to support communication among said plurality of terminal nodes.
