Presence-Based Integration of Wireless Sensor Network and IP Multimedia Subsystem: Architecture Implementation and Case Studies Arif Kadiwal Services are the main driving forces of the Telecommunication industry. In old days the traditional networks e.g. PSTN and mobile cellular networks provide basic services to customers such as voice call, SMS. Unlike mobile cellular networks, Internet provi...

Wireless mobile communications technology has been evolving rapidly in the past decade. The number of mobile subscribers has reached 2 billions and is expected to reach 3 billions by the end of 2010. Most countries have already deployed or have started to deploy the third generation (3G) wireless cellular networks. In 3G, in addition to traditional voice service, users are provided with multi-m...

Keywords: Mobile data offloading WiFi Opportunistic networks Delay tolerant networks Mobility Peer-assisted communications a b s t r a c t Data offloading through WiFi networks has been identified as a promising solution to cellular network congestion caused by the ongoing explosive growth in mobile data traffic. In this paper, we propose Cost-Effective Multi-Mode Offloading (CEMMO) that enhanc...

in this paper, linear matrix inequality (lmi) approach for synchronization of chaotic fuzzy cellular neural networks (fcnns) with discrete and unbounded distributed delays based on sampled-data controlis investigated. lyapunov-krasovskii functional combining with the input delay approach as well as the free-weighting matrix approach are employed to derive several sufficient criteria in terms of...

Cellular mobile networks are used by more than 4 billion users worldwide. One effective way to meet the increasing demand for data rates is to deploy femtocells, which are lowpower base stations that connect to the mobile operator through the subscriber’s residential Internet access. Yet, security and privacy issues in femtocell-enabled cellular networks, such as UMTS and LTE, still need to be ...

Objective(s): The increasing rate of over using cell phones has been considerable in youths and pregnant women. We examined the effect of mobile phones radiation on genes expression variation on cerebellum of BALB/c mice before and after of the birth. Materials and Methods: In this study, amobile phone jammer, which is an instrument to prevent receiving signals between cellular phonesand base t...
