Description
Summary:Signal Strength estimation is important aspect for planning of wireless networks and for generating radio signal maps. There is a variety of approaches to estimate the signal strength in indoor environment that is broadly classified as empirical model based signal strength estimations and deterministic model based signal strength estimations. Empirical models are widely used models for the received signal strength mapping and estimations but they always have a problem of reduced accuracy. Wall attenuation models are considered to be the model widely used and the simplest models but it lacks the accuracy whereas D-model is a newly proposed model that is more précised but not fully mature model. This paper compares both these models in terms of accuracy of RSS estimations in indoor environment especially for obstacles like walls and floors.
