Aggregation and propagation of sensor data within neighbor discovery messages in a tree-based ad hoc network
First Claim
1. A method comprising:
- attaching, by a mobile router, to an attachment router according to a protocol requiring establishment of a loopless topology directed towards a root, the attaching by the mobile router based on the mobile router receiving, from the attachment router, an advertisement message;
outputting by the mobile router 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 loopless topology;
receiving by the mobile router a plurality of sensor data messages from at least one attached sensor node, each sensor data message specifying at least one sensor data element specifying a detected sensor parameter;
receiving by the mobile router a third advertisement message from an attached mobile router having attached to the mobile router, the third advertisement message specifying aggregated sensor data;
aggregating by the mobile router the sensor data elements from the sensor data messages with the aggregated sensor data received from the attached mobile router to form second aggregated sensor data; and
generating and outputting by the mobile router a fourth advertisement message to the attachment router, the fourth advertisement message specifying the second aggregated sensor data.

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.

17. An apparatus comprising:
-
means for receiving an advertisement message from an attachment router, the means for receiving further configured for outputting a second advertisement message specifying availability of a prescribed address prefix used by the apparatus, the means for receiving further configured for receiving a plurality of sensor data messages from at least one attached sensor node and a third advertisement message from an attached mobile router having attached to the apparatus, each sensor data message specifying at least one sensor data element specifying a detected sensor parameter and the third advertisement message specifying aggregated sensor data; and means for attaching to the attachment router according to a protocol requiring establishment of a loopless topology directed towards a root, the means for attaching configured for generating the second advertisement message to specify attributes of the apparatus relative to the loopless topology, the means for attaching further configured for generating the second advertisement message in response to attachment to the attachment router, the means for attaching further configured for aggregating the sensor data elements from the sensor data messages with the aggregated sensor data received from the attached mobile router to form second aggregated sensor data, and generating, for output by the means for receiving, a fourth advertisement message to the attachment router and that specifies the second aggregated sensor data.
