Determination of Path Loss Model based on Measurements for IEEE 802.11n in Large Rectangular Room

چکیده
In this paper, path loss (PL) model for IEEE 802.11n in large rectangular room is determined on basis of PL measurements. It is found that PL model can be described by a TGn channel model and free-space model at small distances with PL exponent of 2.67 and 2. At large distances PL model can be described by one-slope model with PL exponent of 1.6. Further, it is determined PL exponent increases in the presence of humans. Finally we investigate that our PL model has less PL so it is better than one-slope model, free-space model and TGn channel model.

Analyzing the Effective Throughput in Multi-Hop IEEE 802.11n Networks
In this paper we characterize the effective throughput for multi-hop paths in IEEE 802.11n based wireless mesh networks. We derive an analytical model capturing the effects of frame aggregation and block acknowledgements, features found in the new IEEE 802.11n standard. We describe the throughput at MAC layer as a function of bit error rate, aggregation level and path length. Using the results ...
متن کاملComplex permittivity measurements at Ka-Band using rectangular dielectric waveguide
The rectangular dielectric waveguide (RDWG) technique has been developed for the determination of the dielectric constant of materials from effective refractive index measurements in the Q and W bands. This paper describes the use of an optimization method in conjunction with the RDWG technique for the determination of both the dielectric constant and loss tangent of materials at Ka-Band. The e...

Abstract— An educational platform is presented here for the beginner students in the Simulation and Artificial Intelligence sciences. It provides with a start point of building and simulation of the manipulators, especially of 2R planar Robot. It also displays a method to replace the inverse kinematic model (IKM) of the Robot with a simpler one, by using a Multi-Layer Perceptron Neural Network ...
متن کاملTowards MAC/Anycast Diversity in IEEE 802.11n MIMO Networks
Opportunistic Routing (OR) is a novel routing technique for wireless mesh networks that exploits the broadcast nature of the wireless medium. OR combines frames from multiple receivers and therefore creates a form of Spatial Diversity, called MAC Diversity [1]. The gain from OR is especially high in networks where the majority of links has a high packet loss probability. The updated IEEE 802.11...

High-speed Wireless LANs based on 802.11 technologies are becoming increasingly ubiquitous. IEEE 802.11n is the last standard toward achieving higher speeds and aims to enhance 802.11 for higher throughput. Few works studied 802.11n medium access control (MAC) layer, but unfortunately, effects of higher physical rates is still unknown to the upper layers and especially routing layer of these ne...
