The Internet, while being increasingly used to provide services efficiently, poses a unique set of security issues due to its openness and ubiquity. We highlight the importance of security in web services and describe how data mining techniques can offer help. The anatomy of a specific security attack is described. We then survey some security intrusions detection techniques based on data minin...

4G (Fourth generation) mobile communications will have higher data transmission rates than 3G i.e. 4G is 3 times faster speed than 3G technology. Mobile communication is continuously one of the hottest areas that are developing at a high speed, with advanced techniques emerging in all the fields of mobile and wireless communications. Current times are just the beginning for deploying 3G mobile ...

Mobile devices offer the opportunity to play games nearly everywhere. Moreover, networked games allow individual players to interact with other people and to participate in a larger gaming world, which also provides for new business opportunities. Hence, we currently see an increased interest from game developers, providers and players in mobile games. However, due to the inherent nature of wir...

Voice-over-IP (VoIP) has rapidly gained popularity in the last years, especially on smartphones platforms. In fact, WLAN chip-sets are becoming more common on smartphones, allowing users to use VoIP services from their mobile devices. On the other hand, the excessive energy consumption of the WLAN chip-set, limits the widespread use of VoIP on mobile phones. As most of the energy is spent when ...

With recent advances in wireless communication technology, mobile computing is an increasingly important area of research. A mobile system is one where independently executing components may migrate through some space during the course of the computation, and where the pattern of connectivity among the components changes as they move in and out of proximity. Mobile UNITY is a language and logic...

The fast growing market for smart phones coupled with their almost continuous online presence makes these devices the new targets of virus writers. It has been recently found that the topological spread of MMS (Multimedia Message Services) viruses is highly restricted by the underlying fragmentation of the call graph. In this paper, we study MMS viruses under another type of spreading behavior:...

With ubiquitous computing and network access now a reality, multiple network conduits will be available to mobile as well as static hosts (for instance, wired connections, 802.11 style LANs, Bluetooth, cellular phone modems, etc). Selection of the preferred mode of data transfer is a dynamic optimization problem depending on the type of application, its bandwidth/latency/jitter requirements, cu...

We examine the communication patterns of millions of anonymized mobile phone users. Based on call records, we construct a communication network where vertices are subscribers and edge weights are defined as aggregated duration of calls, reflecting the strengths of social ties between callers. We observe a coupling between tie strengths and network topology: at the ”local” level, strong ties are...

As mobile IP-access is becoming the dominant technology for providing wireless services, the demand for more spectrum for this type of access is increasing rapidly. Since IP-access can be used for all types of services, instead of a plethora of dedicated, single-service systems, there is a significant potential to make spectrum use more efficient. In this paper, the feasibility and potential be...
