Abstract Localized mobility management is a well-understood concept in the IETF, with a number of solutions already available. This document looks at the principal shortcomings of the existing solutions, all of which involve...

In this paper, we are configuring an Adhoc mode scenario using QualNet as a Simulation tool to study impact of Random Waypoint mobility on QoS issues in MANET like Average end-to-end delay, jitter and throughput by varying number of nodes within a subnet. Different sets of reading were taken for six cases with varying number of nodes from 7 to 100 using CBR traffic type. We found that Random Wa...

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...

In mobility analysis of mechanisms, a relevant problem is how to determine the redundant constraints. Based on the mechanical network approach introduced by Davies, a methodology for identifying the components of the circuit actions is proposed. In this methodology the number of redundant constraints can be calculated as the number of free components of the circuit actions. Thus, the mobility o...

The infinite-sites model with no recombination is extended to include mutations that affect electrophoretic mobility. The model allows the effect of a single-site mutation to have a continuous effect on mobility. Formulae are obtained for the variance of electrophoretic mobility of alleles after an arbitrary lenght of time. A special case of the general model is the case of stepwise production ...

We previously proposed the Orthogonal Code Hopping Multiplexing(OCHM) scheme as a new statistical multiplexing scheme in synchronous downlink and applied the OCHM scheme to IS-95 and Wideband CDMA. OCHM enables a large number of users to share the limited number of code channels through statistical multiplexing. In this paper, we compare OCHM with HDR through link-level simulation. OCHM outperf...

This paper analyzes voice transmission capacity on ad hoc networks by performing simulations related to delay and jitter. We evaluate the influence of QoS provision and mobility on the number of voice transmitting sources. Results show that the maximum number of voice transmissions can be increased when medium access time is reduced by means of a service differentiation mechanism applied to the...

The flow of generalized Newtonian fluids with a rate-dependent viscosity through fibrous media is studied, with a focus on developing relationships for evaluating the effective fluid mobility. Three methods are used here: (i) a numerical solution of the Cauchy momentum equation with the Carreau or power-law constitutive equations for pressure-driven flow in a fiber bed consisting of a periodic ...

Wireless sensor networks (WSN) is emerging technology finds variety of applications in military, movement tracking, industries and medical fields. WSNs are self configurable, self healing networks. This paper is a survey of mobility models that are used in the simulations of sensor networks. I describe several mobility models that represent mobile nodes whose movements are independent and depen...

The paper analyzes effects of occupational and regional mobility on the matching rate using the monthly panel disaggregated on regional and occupational level. The main contribution of the paper is measuring the effect of substitutability between vacancies for different occupations and vacancies in different regions on matchings. The estimates indicate higher regional mobility in West Germany b...
