Architecture for mobile radio networks with dynamically changing topology using virtual subnets
First Claim
1. A method of configuring a radio network having nodes that are subject to dynamically changing topology, comprising;
- partitioning a radio network into a number of physical subnets wherein each physical subnet includes a certain number of network nodes in relatively close proximity to one another;
affiliating each node of each physical subnet with a corresponding node of each of the other physical subnets thus defining a certain number of virtual subnets; and
routing a communications path from a source node of one physical subnet to a destination node of another physical subnet, by routing certain parts of said path within one or more physical subnets during a first transmission phase, and routing remaining parts of said path within one or more virtual subnets during a second transmission phase.

Abstract
An architecture for a radio network having nodes that are subject to dynamically changing topology such as, e.g., a mobile radio network. The network is partitioned into a number of physical subnets wherein each physical subnet includes a certain number of network nodes in relatively close proximity to one another. Each node of each physical subnet is affiliated with a corresponding node of each of the other physical subnets, thus defining a certain number of virtual subnets. A desired communications path is routed from a source node of one physical subnet to a destination node of another physical subnet, by routing certain parts of the path within one or more physical subnets during a first transmission phase, and routing remaining parts of the path within one or more virtual subnets during a second transmission phase.

15. A node structure for a communications network wherein certain nodes of the network are subject to dynamically changing topology, said node structure comprising;
-
transmitter/receiver means for establishing parts of communications paths in the network, and processor means for controlling operations of parts of the node structure; wherein said processor means includes; means for partitioning the network into a number of physical subnets wherein each physical subnet includes a certain number of network nodes in relatively close proximity to one another; means for affiliating each node of each physical subnet with a corresponding node of each of the other physical subnets to define a certain number of virtual subnets; and means for routing a communications path from a source node of one physical subnet to a destination node of another physical subnet, including means for routing certain parts of said path within one or more physical subnets during a first transmission phase, and for routing remaining parts of said path within one or more virtual subnets during a second transmission phase. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
