Resistive RAM (RRAM) is a promising non-volatile memory (NVM) device which can replace traditional SRAM as on-chip storage for logic and data in FPGAs. While RRAM outperforms SRAM by offering high scalability, low leakage power, and near-zero power-on delay, RRAM-FPGAs have limited programming cycles, and different writes frequencies of memory and logic blocks make the challenge more severe. To overcome...
In this paper, we address the problem of allocating channels to wireless users in the multiuser-multichannel dynamic spectrum access (DSA) scenario. To solve this problem, we introduce a special form of multi-armed bandit (MAB), named exploration bandit, into DSA for the first time. Two distributed algorithms are proposed to maximize the channel rewards (e.g., transmission rates) of the users. Meanwhile,...
In general, the distance measuring method could only measure the pattern similarities of the time series with the same length. Through introducing the concept of dynamic time warping distance, this work proposed a way to define the dynamic time warping distance of the sequential patterns and finally carry out simulation experiments based on the defining the similarities of meta patterns.
Traffic routing plays a critical role in determining the performance of a wireless mesh network. To investigate the best solution, existing work proposes to formulate the mesh network routing problem as an optimization problem. In this problem formulation, traffic demand is usually implicitly assumed as static and known a priori. Contradictorily, recent studies of wireless network traces show that...
