Comparison of traffic performance predictions for three different handoff-region models

A comparison of traffic performance predictions is shown for three different handoff-region models. The first model is based on a statistical approach assuming an exponential distribution of the handoff-region dwell time. The other two models are newly proposed and based on the fact that the distribution of the dwell-time in the handoff region can be derived only using a priori cell parameters such as cell geometry, mobile velocity distribution, channel numbers and etc. In the second model, the distribution of the dwell-time in the handoff region has been derived in closed form, while the handoff region is approximated as a rectangle. In the third model, no approximation on the geometry of the handoff region has been made, while the handoff dwell-time distribution is expressed in an integral form.
