This paper proposes an adaptive frame layer rate control scheme for H.264 by introducing a linear model to predict the mean absolute difference (MAD) of current frame by that of previous one. The target bit rate for each frame is computed by adopting a fluid flow traffic model and linear tracking theory. The corresponding quantization parameter is computed by using a quadratic rate– distortion ...

Each sensor node in wireless network comprises of different processing ability with multipath energy sources, resulting in traffic while performing routing. Control of traffic through multipath routing in sensor network poses a serious challenge during packet transfer due to different characteristics of sensor nodes like beam, temperature and seismic sensors minimizing the desired throughput. I...

We analyze the performance of a generic feedback ow control mechanism which captures the properties of several such mechanisms recently proposed in the literature. These mechanisms dynamically regulate the rate of data ow into a network based on feedback information about the network state. They are used in a variety of networks and they have been advocated for upcoming high-speed networks. How...

It is well established that increased network transmission speed reduces the e€ectiveness of feedback-based adaptive rate control mechanisms, due to the increased bandwidth propagation delay product. In this environment, di€erences in the propagation delays associated with the controlled sources become larger when measured in slots (transmission time of information unit), potentially inducing s...

Three strategies for improving the performance of point-to-point Bluetooth links are presented. All of the strategies are implemented on the host computer, and therefore no modification of the Bluetooth standard is necessary. The first strategy is custom error control coding, which is achieved by transporting BCH code words within AUX1 packets. The second concept is adaptive rate control, which...

Conventional quaternion based methods have been extensively employed for spacecraft attitude control where the aerodynamic forces can be neglected. In the presence of aerodynamic forces, the flight attitude control is more complicated due to aerodynamic moments and inertia uncertainties. In this paper, a robust nero-adaptive quat...
