Abstract
In an embodiment of a wireless network, when a node joins the network and receives a routing advertisement, such a node transmits the routing advertisement to all its neighbors. The node then receives transmission from the neighboring nodes indicating interest in joining the advertised network. If more than a threshold number of neighboring nodes are interested in the advertised route, the newly joining node inserts the route advertisement in a beacon transmission. If there is not a threshold level of interest, the node unicasts only to the neighbors who indicated interest in the advertised network. In an embodiment, the node repeats the above steps on a predetermined time basis (e.g., one per day) in order to determine interest in the advertised route that may have newly arisen.
