Increasing demand in multimedia streaming has led to the advancement of Internet speed, reliability and other techniques. The 3GPP LTE network uses eMBMS protocol for broadcasting and multicasting the multimedia streaming, still the base station overloading has become an alarming issue due to the growing need of the mobile users. Since bandwidth is scares and limited, many emerging fields such as...
Due to the rapid increase in data traffic, one of the solutions provided by mobile operators is to operate Long Term Evolution (LTE) in the unlicensed 5GHz band, as the licensed spectrum is becoming scarce. Mobile operators can expand their network capacity by operating LTE in the unlicensed band at lower cost when compared with using other licensed bands. Device to Device (D2D) communication, proven...
Device-to-Device (D2D) communication has drawn great interest in academia and industries due to the extended network coverage and reduction of the restrictions of traditional cellular systems. On the other hand, a new paradigm called content-centric networking (CCN) has been proposed for scalable, flexible, and secure services in the future networks. With CCN, it is possible to increase the throughput...
In wireless mobile communication, base station overloading is becoming a huge problem due to increasing multimedia file transferring by the end devices. At first, the device sends a request to the base station and then sends the data bit by bit until the full file transfer is complete. As number of users increase over time, it overloads the base station managing their file transmission. In order to...
Disasters either natural or manmade, is a part of our everyday life and no measures can eliminate the occurrence. But, unpreparedness and unawareness of these disasters enhance the severity of damages and cause the loss of human lives. So after the occurrence of the disaster, it requires all out efforts for rescue operation of the lives trapped or lost. When a person gets trapped in an unknown place,...
This work adopts the paradigm of cloud computing over the framework of Device-to-Device (D2D) communications in LTE-Advanced to enable mobile devices to offer network services to nearby devices, thus acting as mobile cloudlets, and to offload cellular traffic from the core network. Hence, any mobile device seeking a new service can search and discover for nearby services with the help of the LTE-A...
D2D communications is one of the key technologies to enable aggressive spatial frequency reuse in future evolution of cellular systems. While the standardization efforts are far from their final stage there is clear understanding that security is one of the major concerns for proximity services. This is especially the case when one or more communicating stations in a logical cluster do not have an...
