Mobility is a natural personality of Ad Hoc networks. A realistic simulation of user movement in Ad Hoc Network is very important to the network performance. The difficult movement pattern of nodes is significant in the study of Ad hoc Networks. As the existing mobility models cannot realistically model the recognized movement patterns and characteristics of node in any complex area scenarios, ...

Existing studies have extensively used temporalspatial data to mining the mobility patterns of different kinds of travelers. Smart Card Data (SCD) collected by the Automated Fare Collection (AFC) systems can reflect a general view of the mobility pattern of the whole bus and metro riders in urban area. Since the mobility and stability are temporally and spatially dynamic and therefore difficult...

The metropolitan area can be regarded as a multi-functional structure consisting of plural coordinated urban nucleuses. This study aims to clarify the characteristics of urban nucleuses and a spatiotemporal pattern of human mobility in the Manila metropolitan area. Hourly density of human mobility from 00:00 to 24:00 in the whole study area is quantitatively studied. Urban nucleuses with six ty...

In this paper a synthetic mobility model which represents behavior and movement pattern of heterogeneous units in disaster relief and battlefield scenarios is proposed. These operations usually take place in environment without preexisting communication infrastructure and units thus have to be connected by wireless communication network. Units cooperate to fulfill common tasks and communication...

Software mobile agents provide an efficient method for reducing data traffic and latency in mobile software applications. In this paper, we identify that current systems use two basic methods for facilitating a request for mobility. We define Mobility Patterns, and we argue that there are another 6 mobility patterns that can improve data traffic or latency if applied in specific cases. We also ...

In this paper a basic skill vector characterization of occupations is used to examine the relation between human capital specificity and occupational mobility. Specifically, the paper asks, how much occupational mobility is simply moving a given skill or task set around different occupations that use the same skill set, and how much involves major shifts in the skill vectors? The loss of specif...

The extent of and changes in inter-generational mobility of wealth are central to understanding dynamics of wealth inequality but hard to measure. Using estate tax returns data, we observe that the share of women among the very wealthy (top 0.01%) in the United States peaked in the late 1960s, reaching almost 50%. Three decades on, women’s share had declined to one third, a return to pre-war le...

Problem statement: Mobility prediction is the important issue in Personal Communication Systems (PCS). Mobile users moving logs are stored in data grid located in different locations. Distributed data mining algorithm is applied on this moving logs to generate the mobility pattern of mobile users. As new moving logs are added to the data grid, existing mobility pattern becomes invalid and it sh...

In our proposed structure, mobile nodes are organized into nonoverlapping clusters which have adaptive variable-sizes according to their respective mobility. The mobility-based clustering (MBC) approach we are proposing uses a combination of both physical and logical partitions of the network (i.e. geographic proximity and functional relation between nodes, such as mobility pattern etc.) Copyri...
