A Configurable Routing Protocol for Improving Lifetime and Coverage Area in Wireless Sensor Networks
Publikováno v:
Wireless Sensor Network. :311-332
The particularities of Wireless Sensor Networks require specially designed protocols. Nodes in these networks often possess limited access to energy (usually supplied by batteries), which imposes energy constraints. Additionally, WSNs are commonly de

Escaping the local optima trap caused by PSO by hybridization scheme for elongate the WSN's lifetime
Publikováno v:
2017 8th IEEE Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON).
Efficient utilization of sensor energy to prolong the WSN' lifetime is proposed in this paper. A hybrid PSO Genetic sleep scheduling algorithm for WSNs to escape the local optima trap is the focus of this work. The proposed scheme uses a new paramete

This paper aims to present a Lorenz chaotic free-space optical (FSO) communication system (LC-FSO-CS), and to study the impact of FSO channel on a transmitted Lorenz chaotic signal infused by an arbitrary random binary message. It examines and corrob

Since deformation estimation may lead to errors occurring when the camera vibrates, it is necessary to remove the image global motion before computing real bridge deformation. In this study, a combination of image motion correction algorithm and 2D i

This paper utilizes a synchronized Lorenz chaotic drive/response system, which uses Haar filtering and appropriate thresholding in order to detect a transmitted random binary message. Using the Lorenz chaotic attractor to obscure the message, the tra
