Session-Aware Popularity Resource Allocation for Assured Differentiated Services
نویسندگان
چکیده
Differentiated Service networks (DS) are fair in the way that different types of traffic can be associated to different network services, and so to different quality levels. However, fairness among flows sharing the same service may not be provided. Our goal is to study fairness between multirate multimedia sessions for an assured DS service, in a multicast network environment. To achieve this goal, we present a fairness mechanism called Session-Aware Popularity Resource Allocation (SAPRA), which allocates resources to multirate sessions based upon their number of receivers. Simulation results in a multirate and multi-receiver scenario show that SAPRA maximizes the utilization of bandwidth and maximizes the number of receivers with high-quality reception.

Signaling Protocol for Session-Aware Popularity-Based Resource Allocation
The Differentiated Services model (DS) maps traffic into services that offer different quality levels. However, flows are treated unfairly in each service, since the DS model lacks a policy to distribute service bandwidth between flows that form the service aggregate traffic. We present a signaling protocol called Session-Aware Popularity-based Resource Allocation (SAPRA) that fairly distribute...
متن کاملA New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions
Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...
متن کاملA Taxonomy for Multi-Period Resource Allocation Problems at System Edges (MPRASE Taxonomy)
Providing guaranteed QoS, be it statistical or deterministic, necessarily requires allocation of scarce resources. This might happen on a session or on an aggregate basis, nevertheless, it is conceivable that at least at system edges scarcity of resources, exposed in the form of non-negligible (virtual) costs, will prevail to necessitate explicit allocation of resources as opposed to pure overd...
متن کاملSecurity-Assured Resource Allocation for Trusted Grid Computing*
A new trust-based model is developed for optimizing resource allocation in a distributed Grid computing environment. Highly shared resources in a Grid create the insecurity and dependability concerns that hinder distributed applications. We model the Grid resource allocation process as a multi-objective integer-programming problem. Trusted Grid computing power is maximized over multiple resourc...
متن کاملDiffServ Resource Allocation for Fast Handoff in Wireless Mobile Internet
The next-generation wireless networks are evolving toward a versatile IP-based network that can provide various real-time multimedia services to mobile users. Two major challenges in establishing such a wireless mobile Internet are support of fast handoff and provision of quality of service (QoS) over IP-based wireless access networks. In this article, a DiffServ resource allocation architectur...
