This paper proposes a novel velocity support call admission scheme through defining a new directional probability function and a new technique of estimating the reservation time window. The projected velocity-dependent directional probability function, with a negative exponential distribution, is based on the assumption that both the probability of changing direction and the rate of change are higher for slow rather than fast moving mobile units. In this paper, the reservation time window is estimated more accurately through considering the estimated travel distance and average cell dwelling time rather than considering finite number of paths as proposed in many recent studies. The new scheme is compared against the existing predictive mobility support scheme using extensive real-scenario simulations. Results prove the new scheme to be very effective in achieving superior performance in terms of QoS parameters and also reduced number of overhead message transmissions.
