Existing solutions for integrating device-to-device (D2D) communication in cellular networks require added functionalities and consume valuable network resources, mainly in the discovery process. This paper effectively reduces the consumption of valuable resources in the LTE—A network through proposing a new D2D discovery scheme that works for vehicular users. The proposed scheme is able to offload...
The importance of mobility has influenced the emergence of several mobile computing frameworks, one of which is cloud computing. In this paper, we propose a design for a system that allows mobile users to access discoverable cloudlet servers which can provide them with services and resources on demand. The system involves a cloudlet root server that acts as a directory with which cloudlets register...
In this work we seek to achieve VoIP end users' profile privacy without violating the QoS constraints on the throughput, end to end delay, and jitter, as these parameters are the most sensitive factors in multimedia applications. We propose an end-to-end user anonymity design that takes into consideration these constraints in a hybrid environment that involves ad-hoc and infrastructure networks. Using...
The strong potentials that exist in Vehicular Ad hoc Networks (VANETs) has given birth to the concept of Vehicular Clouds, in which cloud computing services are hosted by vehicles that have sufficient resources to act as mobile cloud servers. In this paper, we design a system that enables vehicles in a VANET to search for mobile cloud servers and discover their services and resources. Roadside units...
