a most important phenomenon among organizational resources is creativity along with mobility of staff, while empowerment being the motivator of creativity and mobility. the purpose of this study was an analysis of management and organizational factors necessary for empowerment of iranian agricultural colleges faculty members. research methodology was a descriptive-survey one. the statistical po...

This paper proposes a new hashing and caching strategy (NHC) in order to reduce the overall location management cost in wireless mobile networks. It uses caches whose up-to-date information is responsible for dropping this cost and these caches are updated not only at call arrival time from the calling Mobile Terminals (MTs) but also at call receiving time to those MTs, and even at location reg...

Introduction: Complication of an odontogenic infection to an orbital abscess is not a common presentation. The progression from a simple toothache to a condition that may lead to loss of vision is sudden and severe.   Case Report: We report a rare case in which a patient developed facial cellulitis that progressed to orbital abscess after unsterile dental manipulation by a medical fraudster (“q...

Various services supports are the principal requirements of the Fourth Generation (4G) system; therefore, the need to improve integration of heterogeneous networks is significant. This paper amends EVOLUTE (a project of Information Society Technologies (IST)) to strengthen mobility management. This paper uses Multicast-based Mobility (M&M) to aid Cellular IP (CIP) in micro-mobility management. ...

One of the main issues with Mobile Internet Protocol (MIP) is slow handovers. Mobility protocols are classified as micro or macro depending on the domain of the network. When macro mobility protocols are used in managing localized mobility requirements, they result in slow handovers and delays that result in loss of packets and make these protocols unsuitable for time sensitive applications. Mi...

Typical PMIPv6 supports mobility management for the Mobile Host (MH) in localized domains over variant Wireless Local Area Network technologies. The typical PMIPv6 adopted in reactive mode in which break-before-make technique may concern,which results in long disruption latency and inevitable data traffic loss that negatively affects MH's communication performance. This article proposes a proac...

Seamless mobility management of the mesh clients (MCs) in wireless mesh network (WMN) has drawn a lot of attention from the research community. A number of mobility management schemes such as mesh network with mobility management (MEMO), mesh mobility management (M(3)), and wireless mesh mobility management (WMM) have been proposed. The common problem with these schemes is that they impose unif...

BACKGROUND Older adults who have received inpatient rehabilitation often have significant mobility disability at discharge. Physical activity levels in rehabilitation are also low. It is hypothesized that providing increased physical activity to older people receiving hospital-based rehabilitation will lead to better mobility outcomes at discharge. METHODS/DESIGN A single blind, parallel-grou...

The personal communications services (PCSs) systems can provide ubiquitous and customized services. The key issue, which affects the performance of the whole system, is the location management. In this paper, we propose a region-based location strategy by taking advantage of the user’s movement behavior to improve the performance of the conventional systems. Each mobile user is associated with ...

The IETF Mobile IPv6 protocol provides a mobility management scheme for the Internet. Mobile IPv6 handles macro-mobility and micro-mobility identically. We believe that a hierarchical scheme that separates micro-mobility from macromobility is preferable since it would be more scalable. In this paper, we present a mobility management architecture that makes use of the IPv6 Address format hierarc...
