Wireless Performance Evaluation of Building Layouts Closed-Form Computation of Figures of Merit
Abstract : This paper presents a part of our ground-breaking work on evaluation of buildings in terms of wireless friendliness at the building-design stage. The main goal is to devise building design practices that provide for a good performance of wireless networks deployed in buildings. In this paper, the interference gain (IG) and power gain (PG) are defined as two figures of merit (FoM) of the wireless performance of buildings. The FoMs bridge the gap between building design and wireless communications industries. An approach to derive exact closed-form equations for these FoMs is proposed for the first time. The derived analytic expressions facilitate straightforward and more computationally efficient numerical evaluation of the proposed FoMs as compared to Monte Carlo simulations for well-known indoor propagation models. It is shown that the derived closed-form expression can be readily employed to evaluate the impact of building properties, such as the sizes and the aspect ratios (ARs) of rooms, on the wireless performance. The proposed approach sheds light to architects on evaluation and design of wireless-friendly building layouts.
? We survey the existing work on wireless network virtualization, and classify this work in a coherent and meaningful manner, using virtualization theory.
? One advantage of having an ordered hierarchy of representation levels is that existing physical instantiations for abstract objects can be reused, since it is not an easy task to design a physical instantiation of an abstract system.
? Initially, it was envisaged that overlay networks would be highly programmable platforms for innovation, while simultaneously allowing the existing network infrastructure to be maintained.
? Existing network providers have very few opportunities to distinguish themselves from their competitors and thus they equally have little incentive to develop and deploy new solutions.
? It is shown that the derived closed-form expression can be readily employed to evaluate the impact of building properties, such as the sizes and the aspect ratios (ARs) of rooms, on the wireless performance.
? One important factor impacting the power consumption in small-cell networks is the buildingblockage. In, the LOS probability is analytically and empirically modelled.
? With all the assumptions, we first observe the impact of the room structure on a reference UE located in the center of a circular room with a radius of RW.
? In order to meaningfully evaluate the wireless performance of buildings, the impact of buildings on wireless networks has to be well understood.
• Wireless Network Virtualization (WNV) has been proposed as an extension of (wired) network virtualization to the wireless domain, with the main difference being the wireless links.
• Wireless network virtualization has been proposed as an extension of network virtualization to wireless networks, providing similar potential benefits in terms of flexibility and efficiency.
• We propose a test which determines whether proposed techniques are recursive, at least in theory.
• To the best of our knowledge, spectrum-level virtualization was first proposed in which wireless network virtualization is considered as an extension to the wired network virtualization testbed GENI.

? In this paper, the interference gain (IG) and power gain (PG) are defined as two figures of merit (FoM) of the wireless performance of buildings.
? Different types of buildings have an intrinsic wireless performance which is independent of how densely small cells are deployed, or the massive MIMO array antenna deployed .
? The present work is the first step towards providing guidance, to both civil engineers and architects, on incorporating the wireless performance of buildings at the design stage.
? Taking wireless performance of buildings into account will become indispensable for the design of future smart buildings in which appliances and many other devices and “things” will all be connected wirelessly.
