Location Area(LA) planning has critical impact on cellular network design. It is characterized by the tradeoff between the location updates overhead and the paging cost. The LA size could be made as large as the service area of main switching centre, and hence minimizing the registration overhead at the expense of maximizing the paging cost. On the other hand, if each cell is taken as an LA, th...

Traditional operating systems use magnetic disks as paging devices although the cost of each page fault measured in processor cycles continues to increase In this paper we argue that applications should be given the opportunity to use as backing store either mag netic disk or the memory of idle workstations within the same LAN We have implemented a pager that pro vides this exibility measured i...

User location privacy is a growing concern in cellular networks. It has been recently shown that the paging architecture in GSM networks leaks user location information. In this paper, we first prove theoretically that LTE networks also have the same vulnerability. We then propose a solution making use of a novel signal processing technique, physical layer identification. The idea is to embed u...

Paging for multicore processors extends the classical paging problem to a setting in which several processes simultaneously share the cache. Recently, Hassidim [16] studied cache eviction policies for multicores under the traditional competitive analysis metric, showing that LRU is not competitive against an offline policy that has the power of arbitrarily delaying request sequences to its adva...

In this paper, we propose a new context-aware profile-based location management scheme. Besides temporal context that has been used in previous proposals, it considers spatial context of mobility profiles as well as recent travel trajectories. We present a conceptual framework for the cooperation between the Location Database Management System (LDMS) and the Mobile Host (MH) in keeping track of...

In this paper, we propose an architecture for the MPLS (Multi-Protocol Label Switching)-based micro-mobility management including label switched path setup, packet forwarding, handoff processing, and paging. In order to prevent packet loss during handoff, we propose two packet recovery mechanisms, namely: buffer time-based packet recovery and medium access control (MAC) layer assisted packet re...
