Consensus-based cooperative communications for clustered mobile wireless sensor-actuator networks

摘要

This paper provides a novel framework for cooperative communications between mobile sensor-actuator nodes grouped in spatially isolated clusters with but not limited to scale-free topology, which is known as more robust and immune to random attacks. This cooperative scheme describes the intra-cluster and inter-cluster communications using consensus. The consensus concept is defined and customised for wireless sensor networks and the time to reach consensus is derived and discussed using algebraic graph properties of network topology. In this new scheme, clusters have linkage through edge nodes. We formulate the cooperation behaviour of clusters and the communications between multiple clusters of sensor-actuator nodes is discussed and simulated as well.
