Currently, cellular networks are one of the essential communication methods for people. Providing proper coverage for the users and also offering high-quality services to them are two of the most important issues of concern in cellular networks. The fifth-generation cellular comm
Modularity of cellular networks shows general center-periphery polarization
The modular biology is supposed to be a bridge from the molecular to the systems biology. Using a new approach, it is shown here that the protein interaction networks of yeast Saccharomyces cerevisiae and bacteria Escherichia coli consist of two large-scale modularity layers, cen
Adaptive call admission control and resource allocation in multi server wireless/cellular network
The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and h
Radio resource reservation for heterogeneous traffic in cellular networks with spectrum leasing
Radio channel reservation is used to alleviate call dropping which may occur in two situations: (i) hand-off between cells in cellular networks, and (ii) channel withdrawal in wireless networks with spectrum leasing. In this article, we study a radio resource reservation scheme f
Joint Call Admission Control in Integrated Wireless LAN and 3G Cellular Networks
The fourth-generation (4G) (Liu, 2004) system is expected to support fully integrated services and ubiquitous access anytime and anywhere. Instead of developing a new uniform standard for all wireless communication systems, some endeavors in 4G research focus on the seamless inte
Fuzzy Neural Networks for Channel Management in Heterogeneous Wireless Cellular Networks
In this paper, adaptive channel management approach fuzzy neural networks in heterogeneous wireless cellular networks (ACM-FNN) is presented to efficient resource allocation, and admission control schemes are needed to guarantee quality-of-service (QoS) for differentiated service
Improving Quality of Experience of Subscribers through Post Deployment Network Planning in UMTS Cellular Networks
It is an established fact that cost of churning is a common concern for being profitable in the cellular network service provider’s space. Service providers can view this problem as a service management problem and can have a solution to enhance the stickiness of subscribers by m
Trading CDPD Availability and Voice Blocking Probability in Cellular Networks
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 cha
Radio Resource Management in Heterogeneous Cellular Networks
The evolution of cellular networks from one generation to another has led to the deployment of multiple radio access technologies (such as 2G/2.5G/3G/4G) in the same geographical area. This scenario is termed heterogeneous cellular networks. In heterogeneous cellular networks, ra
Studies on Data Transport Protocols for Wireless Cellular Networks
Mobile Internet technology based on wireless cellular networks has been rapidly deployed over the last several years. In the Internet, TCP (Transmission Control Protocol) is used as a standard transport layer protocol. TCP was developed in the early 1970s and has been continuousl
