Decentralised Load Balancing in Event-Triggered WSNs Based on Ant Colony Work Division

This paper proposes a bio-inspired strategy for decentralized load balancing in event-triggered wireless sensor networks, aiming to improve network service availability. The proposed strategy is based on the behavior of ant colonies and the way these insects divide the work. Following this strategy, nodes will decide whether to process a sensed event based on a probability model, aiming to minimize computational and communication overhead and redundancies. Extensive experimental work shows that the proposed approach is effective, easy to configure, and robust to variations to the network setup. Experimental results show an average improvement of 8% in service availability when compared to the state-of-the-art.
