1. A method, comprising: setting one or more routing update parameters for a directed acyclic graph (DAG) in a computer network, the routing update parameters indicative of when to perform a corresponding routing update operation; propagating the routing update parameters to nodes in the DAG; gathering one or more network statistics of the DAG during operation based on the routing update parameters; in response to gathering the one or more network statistics, determining at least one adjusted routing update parameter based on the gathered network statistics; propagating the adjusted routing update parameter to the nodes in the DAG; adjusting the routing update parameters to a less-aggressive route update policy when specific nodes are running low on power; and adjusting the route update parameters to a more-aggressive route update policy when the specific nodes have sufficient power.
