Context is any information that can enhance a computing system’s relevance, timeliness, and usefulness to the user. Recent research has been devoted to the use of context in a mobile environment, particularly in handling the mobility itself. This chapter will start with defining what context is, how it is represented, and present a generalized system architecture. The authors then look at the p...

This paper investigates mobility management strategies from the point of view of their need of signalling and processing resources on the backbone network and load on the air interface. A method is proposed to model the serving network and mobile node mobility in order to be able to compare the different types of mobility management algorithms. To obtain a good description of the network we cal...

BACKGROUND To cope at their homes, community-dwelling older people surviving a hip fracture need a sufficient amount of functional ability and mobility. There is a lack of evidence on the best practices supporting recovery after hip fracture. The purpose of this article is to describe the design, intervention and demographic baseline results of a study investigating the effects of a rehabilitat...

In draft-kempf-netlmm-nohost-ps, the problems with using global IP mobility management protocols for local mobility and some problems with existing localized mobility management protocols are described. In this document, we explore requirements for localized mobility management in more detail. An extensive gap analysis against the protocols illustrates where existing protocols are able to fulfi...

Even though the PMIP provides mobility solutions, there are many issues of user identity, mobility context of users from a home network to the visiting network, the assignment of home address to a user terminal in a visiting network, identification of the user terminal’s mobility, and identification of MPA and HA. In this paper, we propose a new mechanism with proxy mobile IPv4, as a mobility s...

The mobility in mobile ad hoc networks is an application that uses location information of nodes in a network to identify present location of a node. Since we need to get better QOS, mobility management is considered scalable and dynamic compared to other QoS parameters in mobile ad hoc networks. Mobility management in mobile ad hoc networks are mainly motivated by the adoption of dynamic mobil...
