Abstract
A method of communicating information in a communication network with a plurality of hierarchically addressed nodes includes receiving communication packets identifying 1-hop neighbor node addresses, a number of on-tree neighbors of neighbor nodes transmitting the received packets, and forwarding node addresses of forwarding nodes from which information in the received packets are to be rebroadcast. Further, the method includes identifying each 1-hop neighbor node which should be a forwarding node based on stored addresses and numbers of on-tree neighbors, and producing and transmitting a rebroadcast packet including addresses of forwarding nodes. A communication network system, a communication node in a communication network, and a computer program product include similar features. Communication packets embodied in an electromagnetic wave includes an address, a number of on-tree neighbors of neighbor nodes, and forwarding nodes from which the packets are to be rebroadcast.
