“…This has been feasible thanks to the room electromagnetics theory [5]. Several works have used the Finite-Difference-TimeDomain (FDTD) method for the prediction of the coverage in an indoor/outdoor environment [6], [7]. Likewise, the exposure in an realistic indoor environment may be simulated by discretizing the Maxwell equations, however this solution is unlikely to be feasible as it would require a huge amount of memory in terms of computation resources.…”

Abstract-A simple theory based on room electromagnetics theory is presented. It primarily modelizes the Diffuse Multipath Components (DMC) power density with a simple circuit model, and afterwards include the Line-Of-sight component (LOS) in order to determine the whole-body absorption rate for Ultra-Wide-Band (UWB) system. The model may be very useful for prediction tools in realistic environment.

“…The former approach relies on a deterministic modeling of the wave propagation and provides fine simulations of any environment. The most usual algorithms are ray-tracing based [1] but discrete methods have been also proposed [6]. The high accuracy of these methods is definitely balanced by their high computational cost.…”

In wireless multi-hop networks, there is a growing need for the performance evaluation of protocols and distributed applications. Due to the high complexity of analytical models and the difficulty of setting up large scale testbeds, simulations are generally considered as the most convenient methodology for evaluating the performance of wireless systems. However, evaluating a protocol can be a tedious task as it depends on several factors including the physical layer modeling and the dimensioning of protocol or environment parameters. As a consequence inferring an overall performance for a protocol is a real issue. In this paper, we highlight some main factors that may affect the accuracy of the performance evaluation of protocols using simulations. First, we focus on the physical layer (PHY) modeling which represent a key point for the sake of realism and confidence. Second, we discuss the impact of some protocol parameters on the behavior of the evaluated protocols.
