Systematic Review of Energy Efficient Localization Methods for Wireless Sensor Networks

-

Abstract

The primary task of a Wireless Sensor Networks (WSNs) is to sense theenvironment around, sends the information back. The sensor nodes need to be of lesssize, low on power consumption whichsubstantially constrained the computational capacityof these nodes. So any computational taskinvolving these nodes must be very powerefficient so that the duration of the deployment can beincreased. In this paper, we focus on the estimating the position of unknownsensors along higheraccuracy lower power consumption using the information fromanchor nodes. It is as yet atroublesome issue to locate a precise efficient node locationcomputation algorithm under sensornetworks. This paper presents the literature review on DynamicDistance Vector-Hop (DV-Hop) methodfor sensor node localization to processing computing node location along better precision lesslocalization error.
