Mobility Management Framework of Local Mobility

IP mobility solutions allow mobile nodes to roam while retaining connectivity to the internet. However, as these solutions evolve, mobile node implementations continue to undergo modification. Since mobile nodes represent hundreds of thousands of hosts worldwide, deploying new mobility protocols will become expensive. The main objective of this project was to design a framework that decouples the mobile node from route repair, which reduces the implementation and deployment time of new solutions. The proposed framework reengineers existing IP mobility protocols in order to facilitate the transition for network administrators. The second objective of the project was to provide a prototype of the framework to gain acceptance for our design within the Internet community. The result of this work is a mobility management framework that not only reduces the effects of deployment, but also provides a standard interface to the mobile node.

Decoding kinematic variables from Electroencephalographic (EEG) signals during lower-limb mobility protocols

Over 15% of the population of the world has some kind of disability, and a prevalent type is associated with their lower-limbs. In order to provide this type of disabled people with a mean to restore the mobility they once had, it comes to interest the usage of brain-machine interfaces (BMI). Many BMI studies have been done using the approach of electroencephalography (EEG); however, they tend to use a “classical scheme” which consists of classifying only the movement intention of the user. When this intention is detected, the system is programmed to automatically perform realistic movements according to the user’s wishes. This is why direct decoding from the EEG signals into limb kinematics would be preferable, as it gives the possibility of characterizing the intended movement in detail. A limited number of studies have implemented these “decoding schemes”; nevertheless, they just decode a single type of movement. This work will show some of the different methods currently used for decoding, as well as their comparison and performance for different sets of types of movements.

Future Trends in Mobile-Fixed Integration for Next Generation Networks

In recent years, the growth the in the number of heterogeneous interconnected systems, as well as the emergence of new requirements in applications and services are progressively changing the original simplicity and transparency of the Internet architecture. When this architecture was designed, the main goal was to interconnect stationary host. Therefore, the appearance of mobile communications has made necessary to adapt traditional protocols in order to accommodate mobile users. This implies a new interaction between the mobile network and the fixed access network. This paper describes the main IP mobility protocols both centralized and distributed paradigms, and emergent approaches based on software defined networking. Moreover, a novel classification is presented, which relates the integration of the mobility protocol with the access network. Analytical models evaluate the registration updates cost and the packet loss rate of the classified protocols.

SRMIP

Existing mobility protocols suffer from multimedia and data transfer disruption when crossing cities' boundaries by trains or cars. Session continuity in wide area motion is an officially raised goal by 5G-PPP vision. This research adopts 5G methodology by using software defined networking to propose a new mobile IP framework that facilitates seamless handover and ensures session continuity in standard and wide area coverage. The same uninterruptible experience is used to extend smart indoor services with effective offload mechanism to avoid core network congestion. Performance excels existing protocols in setup and handover delays as of eliminating 4G LTE bearer setup/release out-band signaling and isolating user's packets in OpenFlow virtual path that is recursively established in-line with IP address allocation. Handover cross cities in wide area motion becomes feasible with lower latency than LTE handover inside city. Throughput is instantly restored after handover while standard packets are wire speed forwarded as of tunnel headers' elimination and OpenFlow hardware abstraction.

Implementation of a Progressive Mobilization Program in a Medical-Surgical Intensive Care Unit

BackgroundCurrent literature supports implementation of progressive mobility protocols in intensive care units. Education can help nurses overcome barriers to mobility and increase knowledge about the positive effects of mobility.ObjectiveTo evaluate the effect of education for a progressive mobilization program for intensive care nurses on knowledge and performance.MethodsA pretest-posttest evaluation was conducted for 41 nurses, and a chart review was performed before and after implementation of the educational intervention to evaluate changes in knowledge and mobilization.ResultsScores after the educational intervention were significantly higher than scores before the intervention (t = 2.02; P < .001). Overall mobilization (P = .04) and dangling (P = .01) increased significantly after the education. No significant increases occurred in ambulating or getting patients up to a chair.ConclusionsMobilization education was effective and increased nurses’ knowledge about the benefits of mobility for critically ill patients. The educational program also affected how nurses performed mobility interventions. Although provision of education had positive effects on patients’ mobility, leadership and coaching are still important components in implementing change.
