Area of Science:

  • Computer Science
  • Network Engineering
  • Data Science

Background:

  • Mobile crowdsensing (MCS) is gaining traction in space-air-ground-sea integrated networks (SAGSINs).
  • Dynamic environmental conditions and variable participant capabilities in SAGSINs challenge data quality and coverage in MCS.
  • Existing MCS approaches struggle with the complexities of SAGSINs.

Purpose of the Study:

  • To propose a novel UAV-assisted cluster-based task allocation (UCTA) algorithm for MCS in SAGSINs.
  • To address the challenges of data quality and coverage in dynamic SAGSIN environments.
  • To improve the efficiency of task allocation in MCS within SAGSINs.

Main Methods:

  • Introduced edge nodes and a three-layer hierarchical system (Platform-Edge Cluster-Participants) with UAV assistance.
  • Developed an edge-aided attribute-based clustering algorithm to organize tasks, reducing communication and computation overhead.
  • Employed a greedy selection algorithm for optimal task assignment within clusters.

Main Results:

  • The proposed UCTA algorithm demonstrated superior performance compared to three benchmark algorithms.
  • Significant reduction in communication overhead and computational complexity was achieved.
  • Enhanced efficiency in task allocation for MCS in SAGSINs was validated through extensive simulations.

Conclusions:

  • The UCTA algorithm effectively improves data quality and coverage in MCS within SAGSINs.
  • The hierarchical structure and clustering approach are key to the algorithm's success.
  • UCTA offers a promising solution for efficient and effective mobile crowdsensing in complex integrated networks.
