Abstract :
In the simulation analysis of wireless network, the speed of nodes is an important property of mobility. The faster the nodes move, the more unstable the network is. Meanwhile, in theoretical analysis, link failure rate is widely used to modeling the stability of a wireless network. This paper presents an analysis of a simplified mobility model and shows that the link failure rate is positively correlated with the average speed of nodes in this model. Though this result is based on a mobility model with many restrictions, a simulation evaluation suggests that the result still holds in the popular random waypoint model and random direction model.
