An efficient mobile video streaming system needs to cope with unstable network bandwidth and limited battery life. We propose a novel streaming system which jointly considers picture quality, bit-rate and energy consumption. Reducing the spatial reso

The requirement of agile adaptation to varying resource constraints in mobile systems motivates the use of a service-oriented architecture (SOA), which can support the composition of two or more services to form a complex service. In this paper, we p

Rapid advances in wireless sensor networks require routing protocols which can accommodate new types of power source and data of differing priorities. We describe a QoS-aware geographic routing scheme based on a solar-cell energy model. It exploits a

Combining broadcast and mobile phone technologies, 3GPP2 has introduced the Broadcast and Multicast Services (BCMCS) architecture to deliver multimedia content over cdma2000 1xEV-DO wireless networks. In designing a mobile device to support multimedi

Mobile applications require software reconfiguration to improve resource usage and availability. We propose a power-aware reconfiguration scheme that (1) moves energy-demanding applications to proxy servers, and (2) adjusts the fidelity of mobile app

Wireless video sensor networks (WVSNs) require video data from sensor nodes to be delivered efficiently. Cameras in adjacent video nodes tend to have correlated fields of view (FoVs) or overlapping part when a sufficient number of video sensors are d

Conservation of battery power is one of the main issues in mobile computing. In this paper, we propose to exploit a grid infrastructure to extend the battery life of mobile devices based on the contexts of mobile applications, devices, and grid syste

Most existing routing protocols for wireless sensor networks have energy efficiency as their main objective. But for WSN systems in which various types of data coexist, a different QoS (quality of service) metric is required. We describe a mission-or

3GPP2 has recently introduced the Broadcast and Multicast Services (BCMCS) architecture for cdma2000 1xEV-DO wireless networks to enable service providers to broadcast multimedia content such as MPEG-4 video. For MAC-layer forward error correction th

We analyze the performance of MAC-layer Reed-Solomon error recovery in the cdma2000 1xEV-DO Broadcast and Multicast Services (BCMCS) environment, with respect to the size of the error control block (ECB) and the air-channel condition, and establish t
