Effective paging schemes with delay bounds as QoS constraints in wireless systems
TLDR
Three new paging schemes, reverse, semi-reverse and uniform, are introduced to provide a simple way of partitioning the service areas and decrease the paging costs based on each mobile terminal's location probability distribution.Abstract:
In this paper new paging schemes are presented for locating mobile users in wireless networks. Paging costs and delay bounds are considered since paging costs are associated with bandwidth utilization and delay bounds influence call setup time. In general, location tracking schemes require intensive computation to search for a mobile terminal in current PCS networks. To reduce the paging costs, three new paging schemes, reverse, semi-reverse and uniform, are introduced to provide a simple way of partitioning the service areas and decrease the paging costs based on each mobile terminal's location probability distribution. Numerical results demonstrate that our approaches significantly reduce the paging costs for various probability distributions such as uniform, truncated discrete Gaussian, and irregular distributions.read more

Movement-based location update and selective paging for PCS networks
TL;DR: In this paper, the authors proposed a mobility tracking mechanism that combines a movement-based location update policy with a selective paging scheme, where each mobile terminal only keeps a counter of the number of cells visited and a location update is performed when this counter exceeds a predefined threshold value.

Mobility modeling, location tracking, and trajectory prediction in wireless ATM networks
TL;DR: A hierarchical user mobility model is developed that closely represents the movement behavior of a mobile user and that, when used with appropriate pattern matching and Kalman filtering techniques, yields an accurate location prediction algorithm, HLP, or hierarchical location prediction, which provides necessary information for advance resource reservation and advance optimal route establishment in wireless ATM networks.

Mobile users: to update or not to update?
TL;DR: This paper considers both memoryless movement patterns and movements with Markovian memory along a topology of cells arranged as a ring and analyzes the performance of each one of the three strategies under such movements, and shows the performance differences between the strategies.
