The traffic in the high-speed wireless multimedia network will be a mixture of voice, video and data messages having a large variety of characteristic and inherent requirement. The present work is a medium access control protocol for time division-code division multiple access system to distribute the available bandwidth among the mixture of different traffic classes depending upon their quality of service requirement. The proposed scheme is the combination of packet scheduling algorithm and packet allocation algorithm. The packet scheduling is based on the packet loss probability and total traffic waiting for transmission in the system. It maximizes the fairness of the system. It also maintains the packet loss probability of all the users in the environment within a limit The packet scheduling algorithm varies the receive power threshold per packet slot dynamically in case the system packet loss probability and/or system average delay crosses a threshold. The packet allocation is based on the number of packet slot per frame. The performance of the scheme is evaluated in a cellular environment consisting of large number of cells with active users having different multimedia applications. The proposed scheme outperforms existing schemes in terms of delay, throughput and packet loss probability.

In this paper, we propose a fast mode decision algorithm with macroblock-adaptive rate-distortion (R-D) estimation for intra-only scalable video coding (SVC). We make use of the log-linear R-D relationship of inter-dependent layers to predict the better performer among the Intra4x4 and Intra8x8 prediction types at the enhancement layers. Based upon the base-layer chosen prediction type, we can further reduce the number of candidate modes. In addition, to ensure the best trade-off between complexity and coding efficiency, the Intra16x16 prediction is retained and enabled only for coding high-resolution videos with smooth image contents. Comparing to the Joint Scalable Video Model v.8 (JSVM 8), an encoder time saving from 49% to 64% depending on the encoder configurations, is achieved with negligible penalty in coding efficiency.

We consider the task of learning mappings from sequential data to real-valued responses. We present and evaluate an approach to learning a type of hidden Markov model (HMM) for regression. The learning process involves inferring the structure and parameters of a conventional HMM, while simultaneously learning a regression model that maps features that characterize paths through the model to continuous responses. Our results, in both synthetic and biological domains, demonstrate the value of jointly learning the two components of our approach.
In this paper, a real-time scheduler designed for virtual machine (VM) is proposed. In traditional VMs, low throughout and long response time are the typical problems encountered due to the sharing of processor time a...
