A Novel Mobility Model with Abrupt Event Influence to the System Performance of Mobile Cellular Networks

摘要：

We demonstrate in the paper that the appliedmobility model has great influences on the system performanceof mobile cellular networks. We develop a novel mobilitymodel with Abrupt Event Influence (AEI), as well as thesystem model, to study to what extent the influences will be,with focusing on the mobility model simulation. We concernthe parameters that determine the system performance ofmobile cellular networks. We show in this paper that theseparameters vary while user mobility changes, but the effectsare interactive. Since handoff calls are given a higher priorityover new calls and GC mechanism is employed, our analysisshows that a mature mobile cellular network should make useof user mobility characteristics and dynamically adjust itsreservation threshold of the handoff call requests. Extensivesimulation results validate our analysis.
