This paper describes a novel framework for managing connections to mobile hosts in the Internet. The framework, SLM, integrates the notions of Quality of Service management and mobility management and forms a base for overall session management. We compare SLM with the currently most widely adopted mobility management framework Mobile IP, and show how some of Mobile IP’s deficiencies are overco...
Realistic mobility pattern generator: design and application in path prediction algorithm evaluation
A platform for the simulation of mobility functions (e.g., protocols, and application architectures) is presented. This platform, named RMPG, is based on the assumption that real humans exhibit considerable spatial and temporal regularity in their moves. We base our simulation environment on the random way-point algorithm incorporated in the ns tool. Using the Java-based RMPG we performed a ser...

In this paper we present a software architecture which facilitates nomadic computing in an Open Distributed Computing environment. We introduce a model for the description of mobile objects (users, computers and application objects) and their types. The descriptions create an information base for protocols managing mobility of the mobile objects. We present an architecture of servers which exte...
A mobile ad-hoc network (MANET) is collection of intercommunicating mobile hosts forming a spontaneous network without using established network infrastructure. Unlike the cellular or infrastructure networks who have a wired backbone connecting the base-station, the MANETs have neither fixed routers nor fixed locations. Their performance largely depend upon the routing mechanism & nature of mob...
EXTENDED ABSTRACT Mobility, from the perspective of a network, is the ability to change network points of attachment. Support for mobility can be provided at the link layer (e.g. cell phones, 802.11) or at the network layer (e.g. Mobile IP). Link layer solutions are limited to point-to-point connectivity choices between the mobile and a base station. Network layer solutions are limited to infor...
the mobility result is comparable to that achieved in other ZDEG structures where the GaAs layer has been grown on the modulation doped layer of AlGaAs.” In future designs the precise collector barrier profile will be altered to increase this transfer efficiency. Even allowing for possible parallel conduction in the collector barrier at room temperature in our present structure, the base-base r...
User mobility in wireless data networks is increasing because of technological advances, and the desire for voice and multimedia applications. These applications, however, require handoffs between base stations to be fast to maintain the quality of the connections. Previous work on context transfer for fast handoffs has focused on reactive, i.e. the context transfer occurs after the mobile stat...
The objective of this thesis is to develop methods for a targeted and efficient management of users mobility in heterogeneous mobile networks. This network is characterized by the deployment of different types of cells (macro, micro, pico and/or femto). The massive deployment of small cells (pico and femto) provides a supplementary coverage and capacity to mobile networks, specially in dense ar...
objectives: it is important to recognize any risk factors for the development of injuries in the athletic population. the aim of this study was to investigate the association between joint hyper mobility and low back pain in iranian hyper mobile and non-hyper mobile athletes. methods: 50 athletic patients with low back pain (age=23.20±12.79 years) and 51 healthy athletes (age=24.28±13.70) from ...
