Background: Fiber Wireless access network is the boost to broadband access technology for providing network services to Internet users at a lower cost. Deployment of components in FiWi access network is very crucial since it affects the deployment cost and network performance. Objective: We investigate the planning process for efficient placement of components in FiWi access networks. For optimizing the position of components (wireless routers and ONUs) in the network, a novel nature inspired Reptile Search Algorithm (RSA) is proposed in the paper.

A simulation model and code is developed in MATLAB to get the optimized position of components for existing and proposed algorithms. Result: We compare the performance of proposed algorithm with existing algorithm. The obtained results show that th...

Received signal strength Indicator (RSSI)/ Channel state Information (CSI) is one such statistics available on user device, which can be used to achieve multiple adjuncts network functionalities and few applications. This paper focuses mainly on RSSI based Human activity recognition (HAR), Node identification as applications and Physical layer key generation (PLKG) as security mechanism. HAR utilizes variations in RSSI values to detect presence of human or their activities. Similarly in node identification, on the basis of RSSI and environment between Access point and nodes, access point predicts the node location. Further, one of the emerging research areas PLKG, also uses RSSI preprocessing to achieve better network performance. The paper also presents comprehensive survey on hardware cards installed in user devices and software tools used to quantify RSSI in HAR applications.

Melting point and latent heat are two crucial parameters for any PCM for its use in any thermal storage application. The values of these parameters are normally measured by expensive and time consuming measuring devices. In this paper, three empirical equations are presented to predict the melting point and latent heat of alkanes using carbon number as the only input variable. The theoretical results were found comparable with the experimental results within the error limit of ±3.5% for melting point of alkanes with carbon number between 17 and 60. Latent heat values predicted were also in good agreement with the experimental values. Cite this Article Singh SP, Bhat V.

This gypsum board prepared by placing phase change material in small cells in the form of poly-bags. These poly-bags sandwiched in two layers of the gypsum. The gypsum board used for present investigation has two layers of phase change material with different melting points. This gypsum board is intended to be used as false ceiling and hence can easily be used with existing building. We also present a mathematical model which is a mix of numerical and analytical approach. The mathematical model used in the present study validated using the experimental data. Results of the given model are in good agreement with the experimental data. The validated numerical model used for optimization of melting points of two layers. Effect of the positioning of two phase change material layer is also analyzed. Optimization of parameters evaluated using the absolute mean deviation of room temperature from comfort temperature. Experimental work has been carried out using two identical prototypes made up of laminated ply having gypsum boards attached to their roof. Cooling load analysis has also been conducted to assess the energy saving for the investigated prototype.

Research work in thermal comfort using phase change materials needs to be more compatible with other building materials. This article reviews the preparation and utilization of various organic phase change materials investigated by researchers for thermal comfort in buildings. The effect of mixing of different phase change materials and ensuing chemical processes on the melting point and latent heat was reviewed.
