1. Introduction

The rapid proliferation of low‑cost autonomous platforms (UAVs, UGVs, UUVs) has catalyzed the development of Swarm‑Based Dynamic Surveillance Systems (SDSS), wherein a collective of agents cooperatively perceives and reacts to dynamic phenomena such as wildfire spread, crowd movement, or maritime intrusion. Traditional centralized fusion pipelines cannot scale to the sheer number of data streams generated by modern swarms, leading to communication congestion, single‑point‑of‑failure risks, and excessive energy consumption.

Recent literature has explored decentralized consensus (e.g., gossip algorithms), hierarchical clustering, and edge‑AI inference. Yet, most approaches either ignore heterogeneity of sensor modalities or sacrifice optimality for scalability. To bridge this gap, we propose FSDSS‑548, a Fusion‑Centric architecture that:

  1. Preserves modality‑specific information through local Bayesian belief updates.
  2. Reduces bandwidth via an opportunistic “fusion‑token” that circulates among agents, aggregating posterior beliefs on the fly.
  3. Guarantees convergence to the globally optimal Bayesian posterior under mild connectivity assumptions.

Our contributions are threefold:

  • A formal model of the fusion‑token protocol, including proofs of finite‑time convergence and bounded communication complexity.
  • A comprehensive simulation suite (ROS‑Gazebo + ns‑3) evaluating performance across varying swarm sizes, link qualities, and failure patterns.
  • A real‑world HIL experiment on a 48‑agent quadrotor test‑bed, validating the theoretical claims.

3.1 Cross‑matching & Data Integration

from astroquery.vizier import Vizier
from astropy.coordinates import SkyCoord
import astropy.units as u
# Load FSDSS‑548 catalog
fsdss = Table.read('fsdss548_catalog_v1.fits')
coords = SkyCoord(ra=fsdss['RA']*u.deg, dec=fsdss['DEC']*u.deg)
# Cross‑match to Gaia
gaia = Vizier.query_region(coords, radius=1*u.arcsec,
                           catalog='I/350/gaiaedr3')[0]
# Merge tables (inner join on source_id)
merged = join(fsdss, gaia, keys='source_id', join_type='inner')
  • Adopt a Bayesian hierarchical model to simultaneously fit photometric redshifts and intrinsic scatter (see Section 3.2).

Theorem 1 (Finite‑Time Convergence)

Given B‑connectivity of the communication graph and a token hop budget ( H \geq N \cdot B ), the token belief ( \beta_H ) converges almost surely to the exact posterior ( p(\mathbfxt \mid Z1:N) ), where ( Z_1:N ) denotes the union of all measurements up to time ( t ).

Proof Sketch:

  • The token visits each node at least once within any ( N \cdot B ) window due to B‑connectivity.
  • Fusion at each visit multiplies the token belief by the ratio of the node’s current belief to its prior, effectively injecting the node’s likelihood contribution.
  • By induction over token hops, the product of all injected likelihoods equals the joint likelihood across all agents, yielding the exact posterior.
