Abstract

A Novel Wireless Sensor Network Architecture Based on Cloud Computing and Big Data

“…Figure 5 shows the relationship between the optimal number of layers (L) and the node communication radius (r_com) at different node densities P (the number of nodes per square meter; P [1, 0.3]) in the circle with radius R=l00m. It can be seen from Figure 5 that the inter-node communication radius gradually increased but the corresponding optimal number of layers declined with the decrease in the node density P. The relationship reveals that, the nodes are more likely to communicate with each other if there are lots of nodes, that is, the neighbouring nodes are closer to each other [12,13]. In this case, the communication radius r_com of nodes gets shorter, while the optimal number of layers L grows.…”
