As mobile and personal communication services and networks involve providing seamless global roaming and improve quality of service to its users, the role of such network for numbering and identification and quality of service will become increasingly important, and well defined. All these will enhance performance for the present as well as future mobile and personal communication network, prov...

Mobile devices and networks produce abundant data that exhibit geo-spatial and temporal properties mainly driven by human behavior and activities. We refer to such data as geoMobile data. Mining such data to extract meaningful patterns that are reflective of collective user activities and behavior can benefit mobile network resource management as well as the design and operations of mobile appl...

Cellular mobile networks have enabled ubiquitous communications and largely changed the way we live and work. At the same time, the network itself has been undergoing significant changes in the process of meeting our ever increasing demands on data rate and quality of service. In this article, we show the path of the evolution in both standards and techniques, and provide our vision for the fut...

he use of hand-held mobile phones/cellular phones while driving is a known risk factor for road traffic accidents.1 In Iran, the use of mobile phones has increased dramatically in recent years. However, little research has been done to determine the prevalence of mobile phone use while driving in Iran. We conducted an observational, cross-sectional study to document patterns of mobile phone use...

48 ellular digital packet data (CDPD) [1–3] networks provide wireless data communications services to mobile users by sharing the radio equipment and unused RF channels with Advanced Mobile Phone System (AMPS) networks [6]. Basically, CDPD transmits packet data over idle AMPS channels, and autonomously switches to another channel when the current channel is about to be assigned for voice usage....

Mobile ad hoc social networks are selfconfiguring social networks that connect users using mobile devices, such as laptops, PDAs, and cellular phones. These social networks facilitate users to form virtual communities of similar interests or commonalities. This paper proposes semantics-based mobile social network (SMSN), a novel framework of a fully functional mobile ad hoc social network that ...

In the future, wireless access networks will diversify, and they are quite different in their characteristics. We focus on data transmission rate and area coverage, and assume overlay network composed of hot-spotted network and cellular network. Hot-spotted network indicates highspeed wireless network and very limited communication area due to its spotted cell. A mobile user cannot continuously...

In broadcast service area above communications supported cellular wireless networks, data is communicated to several addressees from a right of entry point/base station. Multicast significantly progresses the network effectiveness to dispense data to multiple addressees as associated to multiple unicast gatherings of the similar data to each receiver independently, by taking improvement of the ...

Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption. Therefore, this paper investigates changes in the instantaneous power consumption of GSM (Global System...
