A new authentication scheme with anonymity for wireless environments

Abstract: Wireless network is susceptible to security attacks because its openness of transmission media. Wireless network security is somewhat more concentrated and complex than that of wired network. Authentication is the most essential procedure to ensure that the service is properly used. But its limited resource, such as weak power supplies and limited bandwidth, must be taken into account in the design of security schemes. In this paper, we present a new and efficient wireless authentication protocol providing user anonymity. Our scheme is based on the hash function and smart cards, and mobile users only do symmetric encryption and decryption. In our protocol, it takes only one round of message exchange between the mobile user and the visited network, and one round of message exchange between the visited network and the corresponding home network. The most significant feature is one-time use of key between mobile user and visited network. Finally, the performance of our scheme is analyzed.

Performance analysis of cellular mobile communication systems with dynamic channel assignment

Abstract: The traffic analysis of small-cell mobile networks with dynamic channel assignment is investigated to determine their blocking performance, using a hybrid method of analysis and simulation. The authors particularly focus on the performance problems presented by networks with heterogeneous cell traffic loads, the impact of traffic volatility among the cells, and the impact of multichannel traffic on the channel blocking probabilities. Significant improvement in network performance with dynamic channel assignment is established by numerical results. >

The future generations of mobile communications based on broadband access technologies

Abstract: The forthcoming mobile communication systems are expected to provide a wide variety of services, from high-quality voice to high-definition videos, through high data rate wireless channels anywhere in the world. The high data rate requires broad frequency bands, and sufficient broadband can be achieved in higher frequency bands such as microwave, Ka-band, and millimeter-wave. Broadband wireless channels have to be connected to broadband fixed networks such as the Internet and local area networks. The future-generation systems will include not only cellular phones, but also many new types of communication systems such as broadband wireless access systems, millimeter-wave LANs, intelligent transport systems, and high altitude stratospheric platform station systems. Key to the future generations of mobile communications are multimedia communications, wireless access to broadband fixed networks, and seamless roaming among different systems. This article discusses future-generation mobile communication systems.

An Empirical Study of the Drivers of Consumer Acceptance of Mobile Advertising

Abstract: The ubiquity of text messaging (SMS) based mobile communication creates new opportunities for marketers. However, the factors that induce consumers to accept mobile devices as an advertising medium are not yet fully understood. This paper examines the drivers of consumer acceptance of SMS-based mobile advertising. A conceptual model and hypotheses are tested with a sample of 4,062 Finnish mobile phone users. Structural equation modeling is used to test five drivers of mobile advertising acceptance: (1) utility, (2) context, (3) control, (4) sacrifice, and (5) trust. The results show that utility and context are the strongest positive drivers, while sacrifice is negatively related to the acceptance of mobile advertising. Despite the concerns about privacy, our results indicate that control and trust are not that important to consumers in mobile advertising.

Handbook of Mobile Communication Studies

Abstract: Mobile communication has become mainstream and even omnipresent. It is arguably the most successful and certainly the most rapidly adopted new technology in the world: more than one of every three people worldwide possesses a mobile phone. This volume offers a comprehensive view of the cultural, family, and interpersonal consequences of mobile communication across the globe. Leading scholars analyze the effect of mobile communication on all parts of life, from the relationship between literacy and the textual features of mobile phones to the use of ringtones as a form of social exchange, from the "aspirational consumption" of middle class families in India to the belief in parts of Africa and Asia that mobile phones can communicate with the dead. The contributors explore the ways mobile communication profoundly affects the tempo, structure, and process of daily life around the world. They discuss the impact of mobile communication on social networks, other communication strategies, traditional forms of social organization, and political activities. They consider how quickly miraculous technologies come to seem ordinary and even necessary--and how ordinary technology comes to seem mysterious and even miraculous. The chapters cut across social issues and geographical regions; they highlight use by the elite and the masses, utilitarian and expressive functions, and political and operational consequences. Taken together, the chapters demonstrate how mobile communication has affected the quality of life in both exotic and humdrum settings, and how it increasingly occupies center stage in peoples lives around the world.
