The Impact of Stationary Notes on the Performance of Wireless Mobile Networks

In this paper, impact of the stationary nodes on the link excess life as an important performance parameter of wireless mobile networks is investigated. First, a model for the link excess life is introduced. Based on this model, the relation between the probability density function (PDF) of the link excess life and the PDF of relative velocity is explored. In fact, the PDF of relative velocity is divided into three PDFs according to the three categories of links. The effect of each group on the resultant PDF of global link excess life for different percentages of stationary nodes is explored. Moreover, an approximation method defined in our previous work is proposed as a tool to evaluate the PDF of link excess life for these three categories of links. Indeed, the proposed method could be easily generalized to solve a more general version of the problem, i.e. determining link excess life when different categories of nodes with different velocity ranges present in the network. A simulation framework is also developed and extensive simulation experiments are performed to validate the theoretical results.
