In Mobile Ad hoc Networks (MANETs), where nodes have limited transmitting power, the transmission is typically multi-hop. The network topology changes frequently due to the unpredictable movement of mobile nodes because each node is free to move arbitrarily with different speeds. Thus, when one node enters in the transmission range of another node a link between those two nodes is established, ...

MANET routing protocols performance is perceptive to mobility and scalability of network. The performance of any routing protocol depends on the duration of interconnection among the nodes in the networks. This interconnections results an average connected path for whole network. This paper evaluates, the impact of three mobility models i.e. File mobility model , Random Waypoint and Group mobil...

BACKGROUND Strength training has been shown to be beneficial in older adults. However, very little data exist on the effects of strength training in older diabetics. METHODS 31 community-dwelling older adults with diabetes (mean age = 66.1 years) were randomly assigned to either an exercise (EX) or control (CO) group. The EX group trained the plantar flexors, knee extensors, knee flexors, hip...

IEEE 802.11 series standards have been widely used to specify the MAC mechanism in wireless networks. The 802.11 DCF has not taken into account of the mobility of wireless stations, instead, it is defined based on the assumption that the mobility is not present or is very low. Mobility of wireless stations downgrades the saturation performance of the IEEE 802.11 DCF. This paper made its efforts...

Traditional mobile ad hoc routing protocols fail to deliver any data in Intermittently Connected Mobile Ad Hoc Networks (ICMN’s) because of the absence of complete end-toend paths in these networks. To overcome this issue, researchers have proposed to use node mobility to carry data around the network. These schemes are referred to as mobility-assisted routing schemes. A mobility-assisted routi...

Residential relocation or mobility is a critical component of land use dynamics. Models of land use dynamics need to consider residential relocation or mobility behavior of households to be able to forecast future population demographics land use patterns critical to activity and travel demand forecasting. Unfortunately, very little is known about residential relocation behavior at the disaggre...

Domestic mobility restrictions to control the spread of COVID-19 are widespread in developing countries, and have trapped millions migrant workers hotspot cities. We show that bans can increase cumulative infections relative a counterfactual sans restrictions. A SEIR model shows bans’ impacts nonlinear duration. empirically test this hypothesis using natural experiment India as well data from C...

OBJECTIVE To study the relationship between spinal mobility, radiographic damage of the spine and spinal inflammation as assessed by MRI in patients with ankylosing spondylitis (AS). METHODS In this subanalysis of the Ankylosing Spondylitis Study for the Evaluation of Recombinant Infliximab Therapy cohort, 214 patients, representing an 80% random sample, were investigated. Only baseline data ...

It is well known that age influences organism mobility. This was demonstrated in vertebrates (such as mammals and birds) but has been less studied in invertebrates with the exception of Drosophila and the nematode Caenorhabditis elegans. Here we studied the influence of age on the mobility of the orb-weaving spider Zygiella x-notata during web construction. The orb-web is a good model because i...

We first study the distribution of path duration in multi-hop wireless networks. We show that as the number of hops along a path increases, the path duration distribution can be accurately approximated by an exponential distribution under a set of mild conditions, even when the link duration distributions are not identical. Then, we develop an approximate model for computing the distribution of...
