Soft resource allocation is an important factor of system configuration which plays a critical role in guaranteeing the performance of multi-tier web service systems. There is a tradeoff between real-time performance and resource consumption, and thus the real-time adjustment of soft resource allocation in response to dynamic workload is quite challenging. In this paper, we propose a real-time soft...
Enabling device-to-device (D2D) communication in cellular network is shown to be a promising candidate in the future fifth generation (5G) wireless network. Specifically, the hybrid architecture leads to flexible and efficient resource allocation for cellular users and D2D users, thereby enhancing utilization of spectrum resources. However, if not properly handled, mutual interference will be significantly...
In this paper, we investigate the energy-efficient transmission problem by resource allocation in SCMA networks. We formulate it as an optimization problem to maximize the network energy efficiency (EE) subject to quality-of-service (QoS) requirements, codebook assignment, power allocation, and subcarrier reuse constraints. Due to its mixed combinatory, we separate codebook assignment and power allocation...
Device-to-Device (D2D) communication underlaid cellular networks has been regarded as a technology with great promise to provide higher transmission rate, lower latency and better energy efficiency in services between user terminals in the future fifth generation (5G) wireless network. In this paper, we consider the resource allocation problem to enhance the system performance. Specifically, we use...
In cloud computing, one of its intensions is tomeet service level agreements (SLAs) under high resource utilization. Cloud service providers normally make policies for the provisioning of resource sharing and performance optimization. As a result, the prediction of performance and resource utilization prior to the implementation deems as a promising and efficient tool for cloud providers. It is a...
This paper proposes two types of fragmentation aware spectrum assignment for fully-distributed GMPLS framework. The cut-avoidance approach achieves lower blocking probability and the block-assign approach improves performance more when requested slot sizes are known.
We propose a distributed control scheme utilizing spectral fragmentation-aware RMSA and flexible active/passive reservation mechanism for dynamic multi-domain software-defined elastic optical networks. Our proposed scheme offers significant blocking probability reduction compared to conventional GMPLS/PCE architecture.
Many emerging applications from various domains often exhibit heterogeneous memory characteristics. When running in combination on parallel platforms, these applications present a daunting variety of workload behaviors that challenge the effectiveness of any memory allocation strategy. Prior partitioning-based or random memory allocation schemes typically manage only one level of the memory hierarchy...
Yuanhe River is a branch of the middle and lower reaches of Ganjiang River in Jiangxi Province. The Yuanhe River is a major source of drinking, irrigation, industrial, hydropower generation, and recreational water. And it flows through some heavy industry cities. So the allocation of wastewater discharge permit is a challenge in total mass control due to the conflicts between environmental equality...
Next generation Internet and wireless telecommunication networks compose a pervasive computing structure. Real large-scale tests, simulation and emulation are the major strategies to construct next generation testbed. Synchronization primitives are critical to ensure finite resource assesses. For performance load and utilization prediction, this research proposes a formal testbed abstraction and contention...
