Heterogeneous network security is a prime concern in the era where billions of human beings and physical devices will get connected through next-generation technologies like millimetre-wave wireless, the internet of things, artificial intelligence and ...

In this paper, we analyze the Observed Time Difference of Arrival (OTDOA) technique to simultaneously estimate the position of the different user equipments and the relative time difference between Node Bs in real UMTS networks. We concentrate on ...

Vehicular networking has gained considerable interest within the research community and industry. The automotive industry is supporting the notion of pervasive connectivity by agreeing to equip vehicles with devices required for vehicular ad hoc ...

Universal Mobile Telecommunication Systems Authentication and Key Agreement (UMTS-AKA) protocol is an enhanced Authentication and Key Agreement (AKA) protocol of Global System for Mobile (GSM) communications. The UMTS-AKA has weaknesses in ...

Nowadays, mobile communications have heterogeneous wireless networks offering variable coverage and quality of service (QoS). The availability of alternatives generates a problem of occurrence of unnecessary handoff that results in wastage of network ...

This paper presents a novel technique for UMTS/WCDMA communication jamming, in which the jamming signal is obtained by reproduction of received signal. The received radio-frequency signal is digitized, delayed, and converted to radio-frequency signal ...

Inherent dynamism in user movement demands for post-deployment tuning of UMTS networks to minimize the total cost of ownership TCO. Conventionally, UMTS operators so far have considered many-to-one mapping of RNCs to MSCs. However, such single-homed ...

The aim of this paper is to design and to develop a novel miniaturized Planar Inverted-F Antenna (PIFA), which is covered Multi-band frequency. The proposed antenna is applied in mobile telephones. We analyze the performance of this antenna in terms of ...

The present paper details a technique for adjusting in a smart manner the position estimates of any user equipment given by different geolocation/positioning methods in a wireless radiofrequency communication network based on different strategies (...

Long Term Evolution (LTE) is the most recent standard in mobile communications, introduced by 3rd Generation Partnership Project (3GPP). Most of the works in literature about LTE security analyze authentication procedures, while handover procedures are ...

This study proposes a single frequency reconfigurable planar invert‐F antenna (FRPIFA) using PIN diodes based on the changes of shorting pin positions. The single FRPIFA operates in four configurations which cover the bands of GSM 900/GSM 850, GPS 1575, ...

In recent years, usage of multimedia applications has increased dramatically, especially after the evolution of 3G and 4G technologies. Moreover, the development of new user devices, such as laptops, Smartphone, etc. increased very steeply and rapidly, ...

In this paper, we address the problem of planning the universal mobile telecommunication system base stations location for uplink direction. The objective is to maximize the total traffic covered and minimize the total installation cost based on data ...

In heterogenous network, there are possibilities of horizontal handover between similar type of transmitters as well as vertical handover between different type of transmitters. Also, an user may be served by a single transmitter under the hard handover ...

Wireless telecommunications technologies are part of everyday life and represent an essential communication mean in almost all activities. Among these technologies WIFI (Wireless Fidelity) and UMTS (Universal Mobile Telecommunications System) are the ...

The authentication and key agreement (AKA) protocol of the Universal Mobile Telecommunication System (UMTS) was proposed to solve the vulnerabilities found in the Global System for Mobile Communications (GSM) systems. The UMTS-AKA provides mutual ...

Broadband mobile networks utilize a radio resource control (RRC) state machine to allocate scarce radio resources. Current implementations introduce high latencies and cross-layer degradation. Recently, the RRC enhancements, continuous packet ...

The growth in Internet usage has been phenomenal over the last decade. During the last few years, more and more of this growth has come from mobile broadband access. The most widely used types of mobile broadband access are based on the standards defined ...

Next generation mobile communication is developing towards heterogeneous overlay networks, which provide multiple access patterns for users. Efficient vertical handoff algorithms among different network are required to meet a user's quality of service. ...

To provide users with real-time service under ubiquitous, heterogeneous wireless access network environment, latency of vertical handoff should be reduced. This paper did a research on UMTS/WALN vertical handoff based on MSCTP(Mobile SCTP) and MSIP(...
