This paper presents a conceptual framework for building a recommendation engine for use in the ubiquitous consumer wireless world (UCWW). The framework is based on the Lambda Architecture and as such provides real-time recommendations at the speed layer and off-time analytical operations at the batch layer. Moreover, at the speed layer, a root server is used for updating the real-time recommendation...
A promising architecture for content caching in wireless small cell networks is storing popular files at small base stations (sBSs) with limited storage capacities. Using localized communication, an sBS serves local user requests, while reducing the load on the macro cellular network. The sBS should cache the most popular files to maximize the number of cache hits. Content popularity is described...
The need to configure the network structure is different from the legacy network system in order to meet the needs of the core network 5G. Legacy network does not satisfy an increase in the increase in connection delay time and the traffic at the centralized model. generating requests and trigger central node which occurs in a number up connection small cell and the terminal will give much burden...

Near Field Communication technology is an emerging concept in the field of data transfer and is rapidly catching on the market by replacing technologies such as Bluetooth, infrared and other modes of data sharing because of its ease of use and diverse scopes that are available using this technology. The NFC technology basically is a descendant of RFID (Radio Frequency Identification) technology, which...
Autonomous wireless networks play an increasingly crucial role in today's society. Harsh environmental conditions, challenging deployment topologies, unreliable (or non-existing) power grids, as well as misguided control procedures of communications infrastructures by governmental authorities have made autonomous communication infrastructures a valuable asset for long-term development and wealth of...
The heterogeneity of current telecommunication access technologies is dramatically increasing the complexity and costs required for the set-up and maintenance of the network by service providers, and it is also posing important limitations in terms of network interoperability from the end-users' perspectives. For these reasons, research on wireless systems has investigated the possibility to deploy...

Mobile and wireless communication has been evolved from the basic model for providing point-to-point (PtP) voice centric services into more complicated service provision technologies with point-to- multipoint (PtM) transmission mode, such as MBMS in 3GPP and BCMCS in 3GPP2. On the other hand, the evolution of mobile and wireless communication has also resulted in a large number of wireless technologies...
Relay is one of the key features being considered for IMT-Advanced systems. The relay architectures defined in IEEE 802.16m and 3GPP LTE-Advanced are optimized only for non-mobile relay, i.e., the Relay Station is attached to a designated Base Station and becomes a part of the fixed access network. A mobile relay architecture, where relay may switch attached BS according to operation demand, will...
