Given a mobility pattern that entails intermittent wireless ad hoc connectivity, what is the best message delivery ratio and latency that can be achieved for a delay-tolerant routing protocol? We address this question by introducing a general scheme for deriving the routing latency distribution for a given mobility trace. Prior work on determining latency distributions has focused on models whe...

QUESTIONS What is the association between mobility and falls risk for people living in residential aged care? Can the Physical Mobility Scale discriminate between residents at risk of falling and those not at risk? DESIGN Prospective longitudinal observational study. SETTING Six residential aged care facilities in Australia. PARTICIPANTS Eighty-seven high- and low-level care permanent res...

Vehicular ad hoc network is formed by cars which are called nodes; allow them to communicate with one another without using any fixed road side unit. It has some unique characteristics which make it different from other ad hoc network as well as difficult to define any exact mobility model and routing protocols because of their high mobility and changing mobility pattern. Hence performance of r...

VANET (Vehicular Ad-hoc Network) is a new technology which has taken enormous attention in the recent years. Vehicular ad hoc network is formed by cars which are called nodes; allow them to communicate with one another without using any fixed road side unit. It has some unique characteristics which make it different from other ad hoc network as well as difficult to define any exact mobility mod...

A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. In this dissertation, we studied the effects of various mobility models on the performance of three routing protocols Dynamic Source Routing (DSR), Ad hoc On-Demand Distance Vector (AODV) and Wireless Routing Protocol...

Charge carrier transport in disordered semiconductors is highly influenced by the defect states near mobility edges. A theoretical model for generalized Einstein relation, namely, diffusivity-mobility ratio, retaining a combination of exponential and Gaussian mobility-gap with square-root distribution extended states, presented this article. The conditions determining diffusion coefficient char...

Spatial mobility is a topical concept of analytical migration science, which makes it possible to assess the desires, readiness and capabilities of the population to move over certain distances and time. In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...

The mobility profiles of gases used in enhanced oil recovery (EOR) have been thoroughly investigated through the coupling operations data mining oilfield and experimental analyses. Mobility as an EOR objective function has not previously applied to characterize potential reservoirs for selection application, even though it is a robust combinatorial that benefits from two petrophysical var...

Routing Protocol performance is strongly affected by user or node mobility in Mobile Ad hoc Network. Performance of any routing protocol for Mobile Ad Hoc Network is investigated and assessed using simulator. Network Simulator 2 uses various mobility models to mimic mobility patterns. Simulating a precise real life user/node mobility pattern is difficult. The ns-2 mobility models attempt throug...
