Abstract

A novel approach has been presented to compute the probabilities of unsuccessful handovers based number of free channels available in the target AP and number of free channels available plus based on the mobility of mobile device. The number of free channels in the AP is 16 and the mobility of the mobile device in the 8 different directions is considered. The directions of movement are 0, 45, 90, 135, 180, 215, 270 and 315 that a mobile can take a turn to. If the mobile device is handed over to the target AP based on the movement of the mobile device, then the proposed model can be used to compute the probabilities of the unsuccessful handover if the number of free channels in the target AP is different than expected with respect to the host AP. The probabilities of the incorrect decision is plotted for the cases of mobile device moving in a direction normal to the boundary and moving along the boundary are plotted.
