Our goal is to characterize the access patterns in a IEEE802.11 infrastructure. This can be beneficial in many domains, including coverage planning, resource reservation, supporting location-dependent applications and applications with real-time constraints, and producing models for simulations. We conducted an extensive measurement study of wireless users and their association patterns on a ma...

Our goal is to characterize the mobility and access patterns in a IEEE802.11 infrastructure. This can be beneficial in many domains, including coverage planning, resource reservation, supporting location-dependent applications and applications with real-time constraints, and produce models for simulations.

It is believed that traditional centralized mobility management cannot satisfy the demands of mobile data traffic which has dramatically expanded for years and will remain at a high growth rate in the long term. And now many efforts are putting emphasis on developing distributed mobility management schemes. This paper discusses the advantages of multiple Home Address (HoA) allocating, which is ...

Location graphs, compact representations of human mobility without geocoordinates, can be used to personalise location-based services. While they are more privacy-preserving than raw tracking data, it was shown that still hold a considerable risk for users re-identified solely by the graph topology. However, is unclear how this depends on duration. Here, we consider scenario where attacker want...

Limited finger joint mobility was assessed in 112 diabetic children, in their first-degree relatives, and in 50 unrelated non-diabetic children. In 42% of the diabetic children there was limited joint mobility, but 14% of them had more severe involvement. Limited joint mobility was correlated with increasing age, early presentation, and longer duration of diabetes. First-degree relatives of aff...

Three hundred and fifty seven subjects (178 males and 179 females) with insulin dependent diabetes mellitus were evaluated for the presence of limited joint mobility of the interphalangeal joints. Sixty six subjects (19%) had stage 1 and 26 subjects (7%) had stage 2 involvement of their interphalangeal joints. The presence of contractures was significantly related to mean longitudinal glycated ...

In Vehicular Ad hoc Networks (VANETs) the mobility of the nodes is the main concern. This mobility of nodes makes the route unstable and unreliable for the information exchange and communication between two nodes in the network. To enhance the performance and throughput of the VANETs, routes between nodes must be reliable and stable. In this paper, we study the significance of path duration and...
