Research ArticleOpen accessIn the abstractThe Impact of Radio Propagation Models on Ad Hoc Networks PerformancesA. Rhattoy, A. ZatniProblem statement: Wireless networks are characterized by a dynamic topology triggered by the nodes mobility. Thus, the wireless multi-hops connection and the channel do not have determinist behaviour such as: Interference or multiple paths. Moreover, the nodes’ invisibility makes the wireless channel difficult to detect. This wireless networks’ behaviour should be scrutinized. Approach: In our study, we mainly focus on … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,848 accessesView PDFCite
