Handover is the mechanism that transfers an ongoing call from one cell to another as a user
moves through the coverage area of a cellular system. As smaller cells are deployed to meet …

Handoff is an essential element of cellular communications. Efficient handoff algorithms are
a cost-effective way of enhancing the capacity and QoS of cellular systems. This article …

Determining the position and velocity of mobiles is an important issue for hierarchical
cellular networks since the efficient allocation of mobiles to large or microcells depends on …

In this paper, we study spectrum management in a two-tier microcell/macrocell cellular
system. Two issues are studied: micro-macro cell selection and frequency spectrum …

Some useful services in cellular radio networks and also a class of handover algorithms
require knowledge of the present position and velocity of mobiles. This paper deals with a …

Hierarchical cellular networks with subscribers of varying mobility are considered. Microcells
are used to address the high-intensity traffic of mainly slow mobility areas, and macrocells …

Multitier networks that provide coverage to the same areas by several cells of different sizes
are useful to accommodate high traffic density while keeping high quality of service. The …

Personal communication systems (PCS) represent a rapidly growing and increasingly
important segment of the telecommunication industry. The goal of PCS is to provide truly …

Although aggressive technology scaling has allowed manufacturers to integrate Giga bits of
cells into a cost-sensitive main memory DRAM device, these cells have become more defect …

Third-generation wireless communication faces the challenges of rapidly increasing mobile
user demand against limited radio bandwidth. Splitting cells into smaller cells can reduce …
