arXiv:2610.40826v1 Announce Type: new Abstract: Distributed consensus-based sensing enables a multi-agent system to collaboratively estimate an unknown state by combining local measurements with information received from neighboring agents. In practice, however, the communication network, transmission delays, and finite-rate communication directly affect the disagreement among agents. On the other hand, agreement among agents does not ensure accuracy, particularly when sensors have different measurement uncertainties. We develop a sampled consensus-plus-innovations framework under realistic wireless network constraints that jointly accounts for inter-agent disagreement and estimation inaccuracy. We derive a computable upper bound on the worst-case steady-state estimation error that captures consensus disagreement due to the communication graph, quantization error, and transmission delay, together with estimation inaccuracy, which accounts for measurement uncertainty against the true state. We then use this bound as a network design objective and propose a semi-distributed auction-based algorithm that jointly modifies the communication graph and link-rate allocation. The proposed method preserves connectivity, converges in finite time to a locally auction-stable network configuration, and reduces the bound on the estimation error at every accepted change. The proposed method has been evaluated on various test cases, and the results show that it reduces the estimation error while maintaining fewer links and allocating moderate link rates in a short time.
