DMDG: A Distributed Data-Aggregation and Routing Protocol for Fleet Wireless Sensor Networks

The main goal of this research is concerning protocols to contain in-motion sensor nodes in large-scale topologies, and constitute a fleet wireless sensor network which can assistant in-flight localization and alignment for carrier-based aircraft. In this paper, we abstract network model according to specific conditions of F-WSN, and select performance indicators to evaluate it. A distributed multiple-weight data gathering and aggregation protocol (DMDG) is proposed, which contains all-sided active clustering scheme and realizes long-range realtime communication by tacical data link under a TDMA/CSMA channel sharing mechanism.An analytical paradigm facilitating the most appropriate choice of the next relay is proposed. Simulation results indicate that DMDG scheme can balance the energy consumption and extend the network lifetime notably, compared with existing clustering protocols, especially in sparse node density or anisotropic topologies.
