There is provided a heterogeneous communication network ( 10 ) preferably conforming to contemporary IPv4-/IPv6-standards. The network ( 10 ) includes several interconnected nodes including one or more candidate devices ( 100, 110, 130 ). Moreover, some of the nodes are operable as data routers ( 60, 100, 110 ). The present invention provides a method for dynamically organizing operation of the routers including using the candidate devices ( 100, 110 ) to undertake routing functions where existing routing nodes become inoperable. Moreover, the method utilizes link local router advertisements for the nodes to make their presence known within the network ( 10 ). Furthermore, the network ( 10 ) employs a watcher to be an arbiter of which of the nodes are permitted to function as routers, and the nodes are arranged to communicate with the watcher if a discrepancy and/or conflict in assignment of router arises during operation. Use of the watcher enables the network ( 10 ) to be more robust on account of its routers being dynamically reconfigurable.
