As the nodes in random waypoint mobility models move far away from the border areas with the lapse of time

resulting in their non-uniform steady-state distribution and difficulty in selecting the optimum μ value in uniform mobility models

this paper presents a mobility model

in which their moving distances in every moving period are subject to the uniform distribution relevant to the network diameter parameters.The experimental results show that the network packet delivery ratio has been increased and the network latency and routing overhead reduced.
