PCA-Guided Routing Algorithm for Wireless Sensor Networks

Table 1

Parameter description.

Parameters	Head description
𝑘	The number of the clusters
𝑁	The total number of the sensor nodes
𝐸elec	The energy consumption per bit when sending and receiving
𝑙	The sending data bit
𝜀mp/𝜀fs	The energy consumption about the amplifier
𝑎	The data aggregating rate. It is application specific, where we assume 𝑎=3 as mentioned in Section 2.
𝑑toBS	The average distance between the CHs and the BS. We assume it = 75 m
𝑑toCH	The average distance between the CHs and the non-CH nodes. From [5], we obtain 𝑑toCH=(1/2𝜋)𝑀^2/𝑘, in which, 𝑀 denotes the area of this field.
