In bandwidth limited networks and network interfaces, dynamic resource allocation can substantially increase the link utilization and also decrease the required network bu ering. In general, there are two important tradeo s e ecting the network utilization. First, tradeo between e ciency of the real-time dynamic resource allocation and the policy controlling the renegotiation frequency. Second,...

Nowadays, there are lots of problems in Cloud data center such as high energy consumption and low efficiency. We model a cloud environment with physical hosts and virtual machines, and design an Energy-Aware Virtual Machine Scheduling strategy (EAVMS) to reduce energy consumption and improve utilization rate by integrating system resource such as computing, storage and bandwidth resources. Expe...

The proliferation of mobile computing devices including laptops, personal digital assistants (PDAs), and wearable computers has created a demand for wireless personal area networks (PANs). PANs allow proximal devices to share information and resources. The mobile nature of these devices places unique requirements on PANs, such as low power consumption, frequent make-and-break connections, resou...

Cloud computing is a network of virtualized servers or virtual data centers that can deliver powerful applications, platforms, and infrastructures as services over the Internet. Virtualization technology based Cloud Computing has the advantages of system scalability. It, however, needs mechanisms to improve its resource utilization and to complement its resource management. So, we propose three...

This paper studies the effect of rerouting for augmenting aggregate based resource allocation in the trade-off between overhead and utilization. Aggregation is a common approach used to address the scalability issue in resource allocation. However, resources committed in bulk may be under utilized while other resource requests are being turned down for lack of resources in some shared links. Th...

INTRODUCTION: Craniosynostosis surgery is commonly performed for children at academic centers across the US. Previous literature has found increased hospital and surgical volume to correlate with better post-operative outcomes and decreased costs. However, the association between annual hospital volume of craniosynostosis surgery on inpatient complications and resource utilization is not well s...

Budget based network admission control (NAC) mechanisms can be categorized into four basically distinct approaches. Since they have different complexity and efficiency, we compare their resource utilization in different networking scenarios. Our results show that the network size, the connectivity, and the internal structure of the network have a significant impact on the resource efficiency. S...

Trait-based approaches provide a mechanistic framework to understand and predict the structure and functioning of microbial communities. Resource utilization traits and trade-offs are among key microbial traits that describe population dynamics and competition among microbes. Several important trade-offs have been identified for prokaryotic and eukaryotic microbial taxa that define contrasting ...
