Machine Learning (ML) techniques are pervasive tools in various emerging commercial applications, but have to be accommodated by powerful computer systems to process very large data. Although general-purpose CPUs and GPUs have provided straightforward solutions, their energy-efficiencies are limited due to their excessive supports for flexibility. Hardware(More)
In this paper, we present a Smart Grid Home Area Network communication infrastructure solution that is based on future next generation heterogeneous wireless systems. The heterogeneous wireless system is composed of several Radio Access Technologies (RATs) available at consumer premises. The smart devices that use Smart Grid applications are assumed to have(More)
As the subscriber number of 3G cellular network escalates, the era of 3G has arrived. Due to the specific network architecture and features, 3G wireless network become susceptible target of new Denial-of-Service (DoS) attacks, such as paging attack and signaling attack via (Radio Access Bearer) RAB establishment/release. In this paper, we introduce a(More)
In a hostile environment, sensor nodes may be compromised and then be used to launch various attacks. One severe attack is false data injection which is becoming a serious threat to wireless sensor networks. An attacker uses the compromised node to flood the network and exhaust network resources by injecting a large number of bogus packets. In this paper,(More)
Flash Memory is a desirable candidate for main memory replacement in embedded systems due to its low leakage power consumption, higher density and non-volatility characteristics. There are two challenges in applying flash memory as main memory. First, the write operations are much slower than read operations. Second, the lifetime of flash memory depends on(More)
NAND flash memory has been widely adopted in embedded systems as secondary storage. Yet the further development of flash memory strongly hinges on the tackling of its inherent implausible characteristics, including read and write speed asymmetry, inability of in-place update, and performance harmful erase operations. While Write Buffer Cache (WBC) has been(More)
Flash memory is becoming the storage media of choice for mobile devices and embedded systems. The performance of flash memory is impacted by the asymmetric speed of read and write operations, limited number of erase times and the absence of in-place updates. To improve the performance of flash memory based systems, write buffer cache has been equipped in(More)
NAND flash memory has been employed as disk cache in recent years. It has the advantages of high performance, low leakage power, and cost efficiency. However, flash memory's performance is limited by the inability of in-place updates, coarse access granularity, and a limited number of write/erase times. In this article, we propose a hybrid nonvolatile disk(More)
Vehicular Ad Hoc Networks (VANETs) are received more and more researchers' attention with their promising functions in road safety by exchanging real-time warning messages through vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication. However, an inaccurate traffic warning message will impact drivers' decisions, misguide drivers'(More)
