Recent research has shown the poor accuracy of widely used simulators in the area of wireless networks. Beside many other parameters two are of particular interest: i) the mobility model, and ii) the radio wave propagation model. The first is responsible for the network topology and the latter for the perceiption of transmitted data. Both have strong impact on the performance of mobile ad-hoc networks,...
The study of wireless and mobile networks is mainly based on simulations. Although simulation environments offer a convenient combination of flexibility and controllability, their largest disadvantage is that the results gained by using them are difficult to transfer into reality. This is due to the complex environment of mobile and wireless networks. In this paper we introduce a hybrid testbed approach,...
