ABSTRACT:
In one embodiment, a method comprises attaching, by a mobile router, to an attachment router according to a protocol requiring establishment of a tree topology having a single clusterhead, the attaching by the mobile router based on the mobile router receiving, from the attachment router, an advertisement message specifying an attachment prefix; outputting a second advertisement message specifying availability of a prescribed address prefix used by the mobile router, and further specifying attributes of the mobile router relative to the tree topology; receiving a plurality of sensor data messages from at least one attached sensor host node, each sensor data message specifying at least one sensor data element specifying a detected sensor parameter; aggregating the sensor data elements from the sensor data messages into aggregated sensor data; and generating and outputting a neighbor advertisement message to the attachment router, the neighbor advertisement message specifying the aggregated sensor data.
