Energy Efficient Anchor-Based Localization Algorithm for WSN
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2013, Vol 1, Issue 3
Abstract
Localization is one of the most fundamental problems in wireless sensor networks, since the locations of the sensor nodes are critical to both network operations and most application level tasks. To solve the localization problem for find out the location of sensor nodes in wireless sensor network, a Anchor based localization scheme for wireless sensor networks with energy efficiency is presented in this thesis. First, we develop a standardized clustering-based approach for the local coordinate system formation wherein a multiplication factor is introduced to regulate the number of cluster head nodes and neighbor nodes and the degree of connectivity among cluster head nodes. The algorithm operates asynchronously without a centralized controller; and in this algorithm location of the cluster heads be known a priori which are called anchor nodes. In this thesis to calculate the distance between the nodes triangulation technique is used. A simulation analysis on a specific numerical example is conducted for specifying the energy efficiency in finding the location by using anchor nodes. Experiments show that our algorithm beneficiary for less energy consumption.
