Abstract

En 中文

Localization of sensor nodes is of utmost importance as the information collected by sensor nodes may be meaningless without the knowledge of its origin. Due to limited battery life and non uniform data loaded in the network, some of the sensor nodes may exhaust their battery early and may cease their intended function. This may lead to partitioning of network, wherein some portion of network may not communicate its sensed data to the sink node. In such situation we need to deploy some additional new nodes in the network. Newly deployed nodes needs to be localized as they are unaware of their estimated location. In this paper, we have proposed a new framework to localize newly deployed nodes in a pre-localized network using GA DV-Hop algorithm. The proposed framework has been simulated for various network topologies such as Random topology, C-shaped topology and W-shaped topology. Simulation results show that our proposed localization framework has a trade off between localization error and energy consumption, i.e. one of the proposed method features high localization accuracy at the cost of high energy consumption. However, it has been observed that proposed methods requires less time for localization as compared to traditional methods.
