Optimization of Wireless Optical Communication System Based on Augmented Lagrange Algorithm

Optimization of an Optical Wireless Communication System

This paper presents a preliminary study aimed to optimize the signal characteristics of an optical indoor wireless communication system for telemedicine and mobile user applications. Specifically, detected signals associated with experimental geometries based on line-of-sight (LOS)-pointto-point-optical link and line-of-sight (LOS)-point-to-pointparallel to a surface-optical links are shown. In...

Coverage Enhancement of Average Distance Based Self-relocation Algorithm Using Augmented Lagrange Optimization

Mobile robots with sensors installed on them are used in wireless sensor networks to generate information about the area. These mobile robotic sensors have to relocate themselves after initial location in the field to gain maximum coverage The average distance based algorithm for relocation process of mobile sensors does not require any GPS system for tracking the robotic sensors, thus avoiding...

Solving Combinatorial Optimization Problems Using Augmented Lagrange Chaotic Simulated Annealing

Chaotic simulated annealing (CSA) proposed by Chen and Aihara has been successfully used to solve a variety of combinatorial optimization problems. CSA uses a penalty term to enforce solution validity as in the original Hopfield-Tank approach. There exists a conflict between solution quality and solution validity in the penalty approach. It is often difficult to adjust the relative magnitude of...

Design and Analysis Optical Wireless Communication Based on “Li-Fi”

The Optical Wireless Communications (OWC) systems are attractive to provide broadband services due to their inherent wide bandwidth, easy deployment and no license requirement. The idea to employ the atmosphere as transmission media arises from the invention of the laser Li-Fi or optical Wi-Fi would be the best optimum solution over Wi-Fi technology, Li-Fi technology was first described and fin...
