Latency-Aware Resource Allocation over Heterogeneous Networks: A Lorentz-Invariant Market Mechanism

Saad Alqithami

Abstract

We present a telecom-native auction mechanism for allocating bandwidth and time slots across heterogeneous-delay networks, ranging from low-Earth-orbit (LEO) satellite constellations to delay-tolerant deep-space relays. The Lorentz-Invariant Auction (LIA) treats bids as spacetime events and reweights reported values based on the \emph{horizon slack}, a causal quantity derived from the earliest-arrival times relative to a public clearing horizon. Unlike other delay-equalization rules, LIA combines a causal-ordering formulation, a uniquely exponential slack correction implied by a semigroup-style invariance axiom, and a critical-value implementation that ensures truthful reported values once slacks are fixed by trusted infrastructure. We analyze the incentive result in the exogenous-slack regime and separately examine bounded slack-estimation error and endogenous-delay limitations. Under fixed feasible slacks, LIA is individually rational and achieves welfare at least \(e^{-λΔ}\) relative to the optimal feasible allocation, where \(Δ\) is the slack spread. We evaluate LIA on STARLINK-200, INTERNET-100, and DSN-30 across 52,500 baseline instances with market sizes \(n\in\{10,20,30,40,50\}\) and conduct additional robustness sweeps. On Starlink and Internet, LIA maintains near-efficiency while eliminating measured timing rents. However, on DSN, welfare is lower in thin markets but improves with depth. We also distinguish winner-determination time from the background cost of maintaining slack estimates and study robustness beyond independent and identically distributed (iid) noise through error-spread bounds and structured (distance-biased and subnetwork-correlated) noise models. These results suggest that causal-consistent mechanism design offers a practical non-buffering alternative to synchronized delay equalization in heterogeneous telecom infrastructures.

Theorem 1

Let $\phi: \mathbb{R}_{\geq 0} \to (0,1]$ be a discount function satisfying: Then $\phi(\delta) = e^{-\lambda \delta}$ for some $\lambda > 0$ (in ms$^{-1}$). $\blacktriangleleft$$\blacktriangleleft$

Figures (3)

  • Figure 1: Spacetime view of two bids. Dashed lines are light-cone boundaries under unit aspect ($c{=}1$). The shaded rectangle marks a causal slab where bids are incomparable; the red line is the frontier where horizon-discounted bids are compared (i.e., where $\theta_1 e^{-\lambda \delta_1}=\theta_2 e^{-\lambda \delta_2}$). Its position depends on the values $(\theta_1,\theta_2)$, the parameter $\lambda$, and how each bid's horizon slack $\delta_i$ changes with emission time. Proper-time lapses $\delta_i$ (horizon slacks) are measured along each worldline from emission to the clearing horizon $H$, with $\delta_i \equiv \Delta\tau_i$.
  • Figure 2: Latency-Arbitrage Index (LAI) curves $g(\Delta)$ for STARLINK-200 and INTERNET-100 at $n=50$ (log scale). For each mechanism, $g(\Delta)$ measures the expected utility gain from reducing a bidder's one-way propagation delay by $\Delta$. Fast-VCG exhibits large timing rents that grow with $\Delta$, frequent batch auctions reduce timing rents only by imposing buffering, and LIA drives the curve to zero (within estimator resolution) while maintaining the horizon-level clearing latency.
  • Figure 3: Empirical evaluation summary. (a,b) Fairness--latency frontier at $n=50$ for Starlink and Internet: timing rent (LAI, $\sup g$) versus mean clearing latency. (c) Winner-determination runtime versus market size (shaded bands show min--max across topologies; $n=1000$ points from Table \ref{['tab:welfare-by-topology']}). (d) Welfare ratio versus market size. (e,f) Robustness of welfare and timing rent under bounded slack-estimation error $\varepsilon$ (iid perturbations, solid; common-mode clock bias, dashed), averaged over Starlink and Internet at $n=50$.
