A novel mobility model with Abrupt Event Influence to the system performance of mobile cellular networks

Abstract

We demonstrate in the paper that the applied mobility model has great influences on the system performance of mobile cellular networks. We develop a novel mobility model with Abrupt Event Influence (AEI), as well as the system model, to study to what extent the influences will be, with focusing on the mobility model simulation. We concern the parameters that determine the system performance of mobile cellular networks. We show in this paper that these parameters vary while user mobility changes, but the effects are interactive. Since handoff calls are given a higher priority over new calls and GC mechanism is employed, our analysis shows that a mature mobile cellular network should make use of user mobility characteristics and dynamically adjust its reservation threshold of the handoff call requests. Extensive simulation results validate our analysis.
