Abstract—Wireless Sensor Networks (WSNs) utilize large numbers of wireless sensor nodes to perform close-range sensing and thus enhance sensing qualities. In typical sensing applications, data packets are flowing from sensor nodes to a base station in a many-to-one network structure. To keep event detection delay at a low value, in applications that require occasion data snapshots, it is always desirable to reduce the duration of a Data Collection Process (DCP). Conversely, for applications that require continuous monitoring, the number of DCPs completed in a given period of time is important for reconstructing an accurate data trend. In Cheng et al. (2013) authors have proposed a delay-aware network structure is proposed for WSNs with consecutive DCPs. The proposed network structure is able to increase the number of DCPs per unit time without imposing extra delay on each single DCP. In this paper we extend their work by adding coverage set filtering. Through simulation we prove that our extension is able to reduce the delay even more.
