Cloud storage (CS) is a type of data storage system widely accepted in information technology communities. Users of CS require reliable and continuous access to data on their stored data storage. Therefore, this study presents a data backup method for data retrieval and access from distinct places based on the access frequencies of a shared folder. The proposed method improves the quality of CS services...
In this paper, we propose a multi-factors cell selection (MFCS) scheme for heterogeneous networks with multimedia traffic. In heterogeneous networks, it is an important issue to determine a suitable access network for call request to support seamless service and high-speed connectivity. The MFCS scheme first chooses candidate cells for call request to satisfy the received signal strength constraint,...
LTE uplink frequency scheduling algorithms have neglected the user equipment's (UE) QoS requirements, relying only on the time domain to provide such requirements when creating the allocation matrix for the next transmission time interval. Two time domain paradigms exist for creating the resource allocation matrix: channel-dependent and proportional fairness. The channel dependent paradigm considers...
Quality of service (QoS), and in particular reliability and low latency, are essential qualities of safety-critical wireless systems for medical applications. However, wireless links are typically prone to bursts of errors, with characteristics which vary over time. We propose a wireless system suitable for real-time remote patient monitoring in which both the necessary reliability and a bounded end-to-end...
One of the most important issues of the fourth generation (4G) wireless networks is the capability of mobile devices of handing off running communication sessions to the appropriate interface. It is widely accepted that the handoff decision must consider users, terminal, and network criteria. In the last ten years, several multi-criteria decision mechanisms have been proposed to solve the handoff...
