چکیده

For providing distributed multimedia applications with end-to-end QoS (Quality of Service) guarantees, resource reservation based control mechanisms should be employed in both of networks and end systems. In this paper, we propose a resource allocation scheme for maximizing the user’s utility, which is represented as relation between benefit obtained through allocated resources and cost paid for them. In the scheme, each client is accommodated in the proper cluster to reduce the load of the server and the networks. We confirm that our proposed scheme can achieve an effective use of resources while providing high quality video transfer. key words utility, resource allocation, QoS guarantees, multicast transfer

Integrated Resource Allocation Scheme for Real - Time Video

To provide distributed multimedia applications with a high-quality video multicast, various end-to-end QoS (Quality of Service) guarantees are required. In the network level, the packet transport delay and loss ratio are considered as important QoS parameters. Regularity of the video encoding and decoding should be controlled in the end-system level. To guarantee these types of QoS, resource re...

ارزیابی سیاست‌های زمان‌بندی در نسل چهارم شبکه‌های سلولی (LTE)

New generation of wireless networks, LTE and WiMAX, supports many services which consume a lot of resources (such as VOIP, Video Conference, Digital Video, Multimedia streams and online Multi-player Games). Supporting multi-media services in wireless communication systems provide new resource allocation challenges. Because of high loads in downlink, efficient resource allocation is vital in dow...

Integrated Resource Allocation for Real–Time Video Transfer to Maximize User’s Utility

Abstract For providing distributed multimedia applications with end–to–end QoS (Quality of Service) guarantees, resource–reservation based control mechanisms should be employed in both of networks and end–systems. Resource reservation within the network can be achieved by virtue of bandwidth allocation mechanisms of Internet RSVP or ATM, and the CPU resource on the end system can be reserved by...

Implementation and Evaluation of Integrated Resource Allocation Scheme for Real-Time Video Transfer to Maximize Users’ Utility

For providing distributed multimedia applications with end-to-end QoS (Quality of Service) guarantees, resource reservation based control mechanisms should be employed in both of networks and end systems. In this paper, we implement and evaluate a resource allocation scheme to allocate both of network and server CPU resources to clients in an integrated manner. For this purpose, we use HiTactix...

Dynamic Resource Migration for Multiparty Real-Time Communication

With long-lived multi-party connections, resource allocation subsystems in distributed real-time systems or communication networks must be aware of dynamically changing network load in order to reduce call-blocking probabilities. We describe a distributed mechanism to dynamically reallocate (“migrate”) resources without adversely affecting the performance that established connections receive. I...
