Establishing incoming calls plays an important role in multi‐tier networks. In a multi‐tier
network, if a mobile station (MS) wants to move between different tiers, it has to register at its …

In multi-radio access networks, it is essential to support multi-tier location management to
mobile stations (MSs) with multi-radio interfaces, in order to deliver incoming calls to …

The multiple registration schemes (MRSs) proposed here are classified into 3 cases by
combining five registration schemes which are power up registration scheme (PURS), power …

In this paper, we propose a new power control scheme suitable for a multi-tier wireless
network. It maximizes the energy-efficiency of a mobile device transmitting on several …

Energy consumption minimization of mobile networks is a growing concern for the research
community in recent years. As networks are most of the time underutilized due to spatial and …

The energy-saving methods are infrequent on hybrid energy supplies, a new energy-saving
management mechanism from cell viewpoint was proposed. The mechanism firstly …

Lately, energy efficiency (EE) in mobile communications is receiving growing attention as its
increasing energy consumption raises concern over climate effects. As a stepping stone to …

To fulfill the urgent requirement for ubiquitous information exchange, the infrastructure of the
next-generation mobile system is developing toward a densely distributed cellular network …

Within the last five years, there has been a cultural shift from wired landlocked connectivity to
pervasive wireless information access. Most emerging mobile devices are now equipped …

Power conservation of communication networks at the system level has received much
attention due to the tremendous increase in the number of infrastructure equipment in recent …
