The Optimum Location for Access Point Deployment based on RSS for Indoor Communication
YesIn indoor wireless communication networks, the optimal locations had been known to deploy the access points (AP's)
which has a significant impact on improving various aspects of network operation, management, and coverage. In addition, develop
the behavioral characteristics of the wireless network. The most used approach for localization purposes was based on Received
Signal Strength (RSS) measurements, which is widely used in the wireless network. As well as, it can be easily accessed from
different operating systems. In this paper, we proposed an optimal AP localization algorithm based on RSS measurement obtained
from different received points. This localization algorithm works as a complementary to the 3D Ray tracing model based
REMCOM wireless InSite software and considered two-step localization approach, data collection phase, and localization phase.
Obtained result give relatively high accuracy to select the optimum location for AP compare with other selected locations. It is
worth to mention that effect of different building materials on signal propagation has been considered with specifying the optimum
location of deployment. Furthermore, channel characterizations that based on path losses have been considered as a confirmation
for the optimum location being selected

Meanwhile, visible light communication (VLC) using light devices such as light emitting diodes (LEDs) has been deemed to be a promising candidate in the heterogeneous wireless networks that may collaborate with radio frequencies (RF) wireless networks. In particular, light-fidelity has a great potential for deployment in future indoor environments because of its high throughput and security advantages. This paper provides a comprehensive study of a novel positioning technology based on visible white LED lights, which has attracted much attention from both academia and industry. The essential characteristics and principles of this system are deeply discussed, and relevant positioning algorithms and designs are classified and elaborated. This paper undertakes a thorough investigation into current LED-based indoor positioning systems and compares their performance through many aspects, such as test environment, accuracy, and cost. It presents indoor hybrid positioning systems among VLC and other systems (e.g., inertial sensors and RF systems). We also review and classify outdoor VLC positioning applications for the first time. Finally, this paper surveys major advances as well as open issues, challenges, and future research directions in VLC positioning systems.Peer reviewe
