The emerging HetNet is asking for new network deployment and management methods with flexibility to handle dynamic user demands and diverse radio environments in a tired RAN infrastructure. In this Brief, we present a new framework in the study of HetNet, namely as cognitive cellular network management (CCN), by applying cognitive radio techniques. As shown in Fig. 2.1, CCN are built upon four ...

Location based service is a positioning method that exploits the already existing infrastructures such as cellular networks or W-LANs. Increasing Demand for Energy efficient networks, we are proposing a clustering technique for compressing the radio database in Login Systems. The aim of the proposed technique is to reduce the computation cost and transmission load in the mobile-based implementa...

Parallel Simulation techniques have been proposed as a possible solution to execution time and memory constraints often found in detailed simulations of Wireless Cellular Networks. However, partitioning represents a major challenge for models that encompass elements of radio propagation phenomena. This paper discusses the partitioning problem with respect to Parallel Discrete Event Simulation a...

PERFORMANCE ANALYSIS OF DPSK/DS-CDMA SIGNALS OVER NAKAGAMI RADIO FADING CHANNELS by Ali A. Jamous Chairman: Dr. Ibrahim Ghareeb Direct sequence (DS) based code division multiple access (CDMA) with differential phase shift keying (DPSK) modulation is an active area of research and has taken on a significant role in recent cellular and personal communication systems. Two basic problems are of maj...

Cellular manufacturing system (CMS) is highly important in modern manufacturing methods. Given the ever increasing market competition in terms of time and cost of manufacturing, we need models to decrease the cost and time of manufacturing. In this study, CMS is considered in condition of dynamic demand in each period. The model is developed for facing dynamic demand that increases the cost of ...

Text telephone devices are text-based terminals that allow the users to communicate by text via fixed-line telephone networks. Since cellular phone systems are sometime subject to severe radio channel impairments and the modem signals of these text telephones are therefore not always transmitted reliably, the Federal Communications Commission (FCC) has required a solution to guarantee a reliabl...

he public's desire for mobile communications and computing, as evidenced by the popularity of cellular phones, pagers, and laptop computers, combined with the rapid growth in demand for Internet access, suggest a very promising future for wireless data services. The key to realizing this potential is the development and deployment of high-performance radio systems. While many proposals for thir...

The fiber-optic radio system was proposed to solve the cost problem of micro/picocell system. In this system, all channel elements in a system can be dynamically assigned when the SDS is used. In this paper, we analyzed the performance of soft handoff used as intergroup handoff in the CDMA based fiber-optic cellular system with SDS. Performance is evaluated in view of blocking and handoff refus...
