In the performance evaluation of a protocol for an ad hoc network, the protocol should be tested under realistic conditions including, but not limited to, a sensible transmission range, limited buffer space for the storage of messages, representative data traffic models and realistic movements of the mobile users (i.e. a mobility model). This paper is a survey of mobility models that are used i...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...

This paper adds to the growing number of studies about mobility and wellbeing in later life. It proposes a broader understanding of mobility than movement through physical space. Drawing on the ‘mobility turn’ in the social sciences, we conceptualise mobility as the overcoming of any type of distance between a here and a there, which can be situated in physical, electronic, social, psychologica...

3 To all these who believe in, hope for, and work towards a more human technology, I dedicate my work. Abstract Mobility management is the cornerstone of cellular philosophy. Mobility analysis gives a deep insight on the impact of the terminal mobility on the cellular system performance. In third-generation mobile communication systems, the influence of mobility on the network performance will ...

–A mobile ad-hoc sensor network usually consists of large number of sensor nodes (stationary or mobile) deployed over an area to be monitored. Each sensor node is a self-contained, battery-powered device that is capable of sensing, communication and some level of computation and data processing. Due to the large amount usage of sensors in the network, it is important to keep each node small and...

Ion mobility has a direct influence on the performance of conducting polymers in a number of applications as it dictates the operational speed of the devices. We report here the enhanced ion mobility of poly(3,4-ethylene dioxythiophene) after incorporation of gelatin. The gelatin-rich domains were seen to provide an ion pathway through the composites.

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...

objectives: the purpose of this study was to determine the functional mobility and balance in the elders after total hip arthroplasty in healthy coparison to elders. methods & materials: the current cross-sectional study was done on 20 patients (70.9±4.2) with hip osteoarthritis 6 months after total hip arthroplasty and 20 healthy subjects (73±5.7) as control group. patient group was assigned w...
