Mobility is an inherent charater of Ad Hoc Networks. Ad Hoc networks are characterized by node mobility and lack of infrastructer. In the past decade , a significant amount of research was devoted to develop mobility models suitable for evaluating the performance of Ad Hoc Network. The goal of this paper is to present a number of mobility models in order to offer research more experienced choic...

Ad hoc networks of wireless devices carried by entertainment park visitors can support a variety of services. In such networks, communication links between the devices sporadically appear and disappear with the mobility of visitors. The network performance strongly depends on how often they encounter each other and for how long the contact opportunities last. In this paper, we study the mobilit...

IP-based Wireless Sensor Networks (IP-WSNs) are gaining importance for their broad range of applications in health care, home automation, environmental monitoring, industrial control, vehicle telematics, and agricultural monitoring. In all these applications, a fundamental issue is the mobility in the sensor network, particularly with regards to energy efficiency. Because of the energy ineffici...

In their study, Brenna and Spandonaro analyzed the mobility into Italian regions. In particular, it analyzes the situation of 5 regions, with very different backgrounds. With this paper, we try to better define the meaning of health mobility and to find its underlying causes. Furthermore, we propose a strategy that could help in controlling mobility flows that currently are the source of health...

realistic mobility models can demonstrate more precise evaluation results because their parameters are closer to the reality. in this paper a realistic fuzzy mobility model has been proposed. this model has rules which are changeable depending on nodes and environmental conditions. it seems that this model is more complete than other mobility models.after simulation, it was found out that not o...

the mobility of entrepreneurs, which is an integral part of human life, can occur in all aspects of occupation and location. finding out the general trends of mobility in entrepreneurship can be used in the effective motivational activities. as sylhet is a remittance and raw materials rich but industrially backward area, the mobility of entrepreneurship in both aspects in this area is to be ana...

Network arrivals are often modeled as Poisson processes for analytic simplicity, even though a number of traffic studies have shown that packet interarrivals are not exponentially distributed. We evaluate 24 widearea traces, investigating a number of wide-area TCP arrival processes (session and connection arrivals, FTP data connection arrivals within FTP sessions, and TELNET packet arrivals) to...
