The two-layer network structure has been widely adopted in wireless sensor networks (WSNs) for managing sensor nodes. In such a structure, the low layer nodes communicate with their cluster head, followed by the cluster-head nodes communicating with the base station operating in either a one-hop or a multi-hop manner. The main focus of node-clustering algorithms is minimizing energy consumption due...
In wireless sensor networks (WSNs), numerous sensors can produce a significant portion of the big data. It remains an open issue how to timely gather and transmit such large amount of data while minimizing data latency through wireless sensor networks (WSNs). On the other hand, spatially correlated sensor observations lead to considerable data redundancy in the network. To efficiently eliminate data...
In this paper, An uneven clustering routing based on ARMA model(UCR-A) was proposed for the "hot spot", and the main ideal is that the entire region is divided into unequal radial level with the base station at the center. Cluster head is chosen based on the residual energy and the relative position. Multi-hop data routing was formed in inter-cluster, and apply ARMA prediction model to the...
