“…As previously stated, in order to analyze wireless channel behaviour, a deterministic approach based on an in-house 3D ray launching code is employed. This simulation code, which considers electromagnetic interaction with the material elements of the scenario, as well as reflection, refraction and diffraction, has been tested in a wide range of complex environments [3][4][5][6][7][8]. The main simulation parameters that have been used for the scenario are shown in Table I.…”

In this work, the massive deployment of wireless sensor networks inherent in the implementation of context aware Smart City environments is presented. A precise estimation considering the topology and the morphology of wide service areas, with a potential large density of transceivers is performed with the aid of in-house deterministic 3D ray launching algorithm, which is specifically adapted to the conditions of large volume and large traffic density. Due to the co-existence of multiple wireless systems (such as wireless local area networks, mobile networks, body area networks or RF proprietary systems), a heterogeneous scenario, in terms of traffic distribution and hence overall interference is present. The precise characterization of coverage areas of all wireless transceivers, as information sources or undesired interference sources, leads to optimal deployment configurations, in which interference levels are minimized, quality of service is enhanced and overall energetic consumption can be optimized.

“…Different applications of this algorithm can be found in the literature, like the analysis of wireless propagation in closed environments [15][16][17][18], interference analysis [19] or electromagnetic dosimetry evaluation in wireless systems [20].…”

Abstract:The use of wireless networks has experienced exponential growth due to the improvements in terms of battery life and low consumption of the devices. However, it is compulsory to conduct previous radio propagation analysis when deploying a wireless sensor network. These studies are necessary to perform an estimation of the range coverage, in order to optimize the distance between devices in an actual network deployment. In this work, the radio channel characterization for ISM 2.4 GHz Wireless Sensor Networks (WSNs) in an inhomogeneous vegetation environment has been analyzed. This analysis allows designing environment monitoring tools based on ZigBee and WiFi where WSN and smartphones cooperate, providing rich and customized monitoring information to users in a friendly manner. The impact of topology as well as morphology of the environment is assessed by means of an in-house developed 3D Ray Launching code, to emulate the realistic operation in the framework of the scenario. Experimental results gathered from a measurement campaign conducted by deploying a ZigBee Wireless Sensor Network, are analyzed and compared with simulations in this paper. The scenario where this network is intended to operate is a combination of buildings and diverse vegetation species. To gain insight in the effects of radio propagation, a OPEN ACCESSSensors 2014, 14 23651 simplified vegetation model has been developed, considering the material parameters and simplified geometry embedded in the simulation scenario. An initial location-based application has been implemented in a real scenario, to test the functionality within a context aware scenario. The use of deterministic tools can aid to know the impact of the topological influence in the deployment of the optimal Wireless Sensor Network in terms of capacity, coverage and energy consumption, making the use of these systems attractive for multiple applications in inhomogeneous vegetation environments.
