The last decade has seen an explosive growth in wireless network services and consequently an increasing demand of high data rates on wireless networks, and the demand of users on real-time traffic is growing. The quality of service (QoS) requirements of different applications are different, for example, the real-time applications are delay-sensitive, yet can tolerant certain data loss. An intrinsic...
Performance evaluation techniques for fundamental graphics algorithms and for algorithms to be used in multimedia and embedded systems are investigated. Models of computation considering only arithmetic and logic operations taken on input data are regarded as inadequate for processors with instruction-level parallelism. For experimental evaluation of graphics algorithms clock-cycle counting is found...
Considering the high packet losses and low, varying bandwidth of GPRS/EDGE network and limited computation power of handheld devices, we present and implement a novel SVC video-on-demand system for hand-held devices over GPRS/EDGE network. For the purpose of handling varying bitrate, we propose a priority based layer switching (PLS) adaptation scheme for SVC stream, which not only performs online...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
Many real-time communication protocols have been studied to guarantee the communication requirements of distributed real-time systems. But, current techniques lack all or most of these requirements specially bounded message delivery time. In this paper we have proposed a Mac layer protocol called RDM+ with concepts similar to Round Data Mailer multi layer protocol. Our simulation results show that...
