A method for routing messages having a routing indicator across linked master/slave configured piconets. At each master node, a routing table is stored and at each hop a receiving master node performs a reception algorithm on the routing indicator, the result enabling the receiving node to identify a target node and whether that node is local to the receiving piconet or a node accessible through a piconet with which the receiving piconet is linked. In the latter instance, the receiving node performs a transmission rule on the result to generate a new routing indicator replacing the routing indicator, which is then transmitted with the message to the identified piconet.
