Due to uncertainties in target motion and limited sensing regions of sensors, collaborative target tracking in wireless sensor networks (WSNs) suffers from low tracking accuracy and lack of reliability when a target cannot be detected by a scheduled sensor. Generally, actuating multiple sensors can achieve better tracking performance but with high energy consumption. Tracking accuracy, reliability,...
In this paper, based on LEACH protocol, improvement is made and the improved protocol DCDA-LEACH is proposed. DCDA-LEACH makes improvements to LEACH with data correlation and data aggregation as the core, introducing the thinking of regionalization. It divides the nodes into regions in accordance with the relevant characteristics of the data to improve the data correlation level within the clusters...
