Abstract
An adaptive link assignment scheme for dynamically changing communication node topologies such as satellite networks, fleets of ships or aircraft, etc. Periodically each node in the network transmits topology information to all the nodes in the network. Then each node determines the degree of connectivity of the network. It is preferred that the network be at least triconnected, and if the network is less than that each node determines what connections it can make to improve the network connectivity. If more than one alternative is available, a choice is made based on line of sight endurance and then on traffic delay. The identification of the selected connection is then broadcast to all the nodes in the network. Each node thus receives the proposed changes from all the network nodes, and each node then resolves conflicts between the broadcast selections and determines what change it should make. Finally, the changes are implemented. The scheme emphasizes network connectivity to bring the network to a triconnected state and then emphasizes line of sight endurance and reduction of traffic delay.
