SMMT - Scalable Mobility Modeling Tool

摘要

In this paper, we present a novel mobility model, called the Scalable Mobility Modeling Tool (SMMT), which is based around a scaleable algorithmic mobility model that can be applied to a large number of possible horizontal environments, from wide area networks (WAN) to local area networks (LAN), to analyze the issues related to mobility management and radio resource management. The SMMT introduces the new concept of poles of gravity (PG) to characterize the spatial and temporal behavior of mobile users in a scaleable way. This technique has been applied to a cellular communications system superimposed on different geographical frameworks consisting of the City Area Model and City Center of Bristol, UK, to investigate the performance issues related to location and paging area and teletraffic issues respectively.
