•Memory requirements have become more strict in time with respect to performance, power, and cost •Keeps innovating technology to correspond to those requirements - Make efforts to extend the value of traditional memory - Figure out innovative memory solution •Close collaboration with partners is essential for delivering the right memory solution.
Wireless communication networks are expanding with the deployment of small cell networks. Energy efficiency becomes a crucial system design parameter in such systems. One approach to increase the energy efficiency is to allocate radio resources in efficient manner. This is done by developing a QoS based optimization framework for Joint bandwidth and power allocation. Energy efficiency in such systems...
Considering that the current information content being exchanged is increasingly multimedia, it is quite natural to the demand for a relatively short time downloading or to a certain extent uploading large information files to the Internet. Mobility is increasingly demanded along with broadband. Certain to locations do not have the necessary infrastructure for broadband. Users that are residing in...
Central to the vision of Smart City is the realization of efficient models that are capable of handling massive amounts of mobile multimedia data in the city's eco-system. Despite the improvement in hardware of mobile devices, challenges associated with analyzing, managing, and sharing of data still exist. As such, the responsiveness to real time applications and bandwidth and wireless constraints...
It is well-known that the spurious fast retransmission and timeout widely exist in the course of vertical handover when a mobile node (MN) moves from a longer transmission delay network into a shorter one. Some solutions for the problems have been discussed in a lot of literatures for non-Cognitive Radio (non-CR) scenarios. One of them, bicasting is the main method to improve the transmission performance...
On the basis of traditional image transmission technology, the medical image transmission strategy based on bandwidth sensitivity and multi-resolution is proposed in mobile transmission environment. According to current network bandwidth, remaining battery power of mobile terminal equipment, screen resolution of mobile device supporting and real-time transmission requirements, the strategy selects...
Due to the upsurge of context-aware and proximity aware applications, device-to-device (D2D) enabled mobile cloud (MC) emerges as next step towards future 5G system. There are many applications for such MC based architecture but mobile data offloading is one of the most prominent one especially for ultra dense wireless networks. The proposed system exploits the short range links to establish a cluster...
Mobile devices have become an important part of our life. Service disruptions can occur because of limited resources of mobile devices such as computation, storage and battery. In this context, mobile cloud computing enables mobile devices to offload their computation and storage to the cloud and get the final result from cloud servers. There are some parameters like bandwidth, delay, jitter and user...
Assembly fixtures that are much smaller than the structure being manufactured, such as an aircraft, must routinely be positioned and docked against the structure on which they act. The major contribution of this article is to develop a variable-impedance-based human-machine control for the docking process. The issues investigated are: (i) impedance control to facilitate intuitive human force input;...

Artificial Immune Systems, a relatively new meta-heuristic for solving optimization-related problems, is investigated in this study to design a cellular channel allocation framework. In this study, mobile hosts are allowed to continue interacting with the cells that they are currently in, even when...
A compact dual-broadband antenna is proposed for 2G/3G/LTE (4G) mobile communications. The radiation unit of the proposed antenna consists of a lower-band element and an upper-band element. The lower-band element comprises a rectangular patch fed by an L-shaped probe, the upper-band element comprises a pair of two folded printed dipole fed by an L-shaped probe as well. The upper-band element is stacked...
It has become apparent that current fronthaul technology cannot be simply extended to meet the projected demands of 5G and beyond mobile systems. This current technology, based on the transport of sampled radio waveforms, has been the preferred option, with analog radio over fiber reserved to relatively niche application scenarios. However, for future systems, it is recognised that different functional...
Active Antenna Systems (AAS) technology is one of several advanced features that enable a mobile network operator to cost-efficiently increase its network capacity to cope with the exponential mobile data traffic growth and the ever more demanding performance requirements. AAS can be exploited to perform e.g. Virtual Sectorisation (ViS), i.e. using beamforming to flexibly position a virtual small...

Recent trends in wireless networking, such as small cells and network function virtualization, strongly suggest that the future cellular network will consist of many sub-networks controlled by self-interest operators competing for a share of the revenues associated with the high demand for service. This paper attempts to analyze the future network performance under these new market conditions, considering...
In this paper, a contiguous carrier aggregation scheme for the downlink transmissions in an inband full-duplex cellular network is analyzed. In particular, we consider a scenario where the base station transmits over a wider bandwidth than the mobiles, while both parties are still using the same center frequency. As a result, the mobiles must cancel their own self-interference over a wider bandwidth,...
Mobile data networks exhibit highly variable data rates and stochastic non-congestion-related packet loss. These challenges result in key performance bottlenecks in current Transmission Control Protocol (TCP) implementations: bandwidth inefficiency and large end-to-end delay. This work addresses these challenges by first developing a Sliding Interval based Rate Adaptation (SIRA) that tracks bandwidths...
The recent advances in both high specification mobile devices and increased user expectations in terms of access to multimedia content have put pressure on the existing mobile networks in terms of traffic. Many users use their mobile devices as their primary means of connecting to the Internet. However most of these users are constrained by the data caps imposed by the network providers and seek connectivity...
