In this paper, A joint Spectrum allocation, horizontal/vertical Handover and opportunistic multi-hop Routing Protocol (SHARP) is proposed to address a few of the most important challenges of multi-hop ad-hoc, fixed or vehicular cognitive radio networks, such as, maximization of spectrum utilization and throughput. Utilizing the proposed joint velocity and average received power (ARP) estimation...

Inspired by online ad allocation, we study online stochastic packing linear programs from theoretical and practical standpoints. We first present a near-optimal online algorithm for a general class of packing linear programs which model various online resource allocation problems including online variants of routing, ad allocations, generalized assignment, and combinatorial auctions. As our mai...

since software systems play an important role in applications more than ever, the security has become one of the most important indicators of softwares.cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. presenting a proper scheduling method can lead to efficiency of resources by decreasing response time and costs. this rese...

data envelopment analysis (dea) is a non-parametric method for assessing relative efficiency of decision-making units (dmus). every single decision-maker with the use of inputs produces outputs. these decision-making units will be defined by the production possibility set. resource allocation to dmus is one of the concerns of managers since managers can employ the results of this process to all...

introduction: efficiency evaluation of universities and faculties is one of the tools that help managers to identify the departments’ strengths and weakness. the main objective of the present research was to measure and compare the technical efficiency of shiraz school of medicine departments using data envelopment analysis (dea) technique. methods: this cross-sectional and retrospective study ...

In this paper, we consider interactions of Internet Service Providers (ISPs) and how these interactions can affect the overall traffic and resource allocation between ISPs. In particular, we consider a simplified two-level hierarchical model wherein there are a single tier-1 ISP and tier-2 ISPs. Each tier-2 ISP needs to pay the tier-1 ISP for the connectivity service. At the same time, a tier-2...

Human error is a significant and ever-growing problem in the healthcare sector. In this study, resource allocation problem is considered along with human errors to optimize utilization of resources in an emergency department. The algorithm is composed of simulation, artificial neural network (ANN), design of experiment (DOE) and fuzzy data envelopment analysis (FDEA). It is a multi-response opt...

The routing problem for shared path protection in multi-domain optical mesh networks is more difficult than that in single-domain mesh networks due to the lack of complete and global knowledge on the network topology and bandwidth allocation. To overcome this difficulty, we propose an aggregated network modeling by underestimation with a two-step routing strategy. In the first step, a rough rou...
