On Distributed Multimedia Scheduling with Constrained Control Channels

IEEE CTN Issue: January 2012

Traditional multimedia scheduling approaches assume perfect control channels where each node has access to the knowledge of its neighbors. However, in practice the control channels are always constrained and nodes can only exchange limited information with their neighbors, e.g., the control packets are lost during the wireless transmission, and the node only has partial network information. In this case, existing distributed multimedia scheduling schemes cannot work efficiently. This paper investigates how imperfect neighbor information affects the multimedia scheduling, and reveals the relationship between the control gain and scheduling performance based on available network and multimedia information.

Toward an Architecture for Monitoring Private Clouds

IEEE CTN Issue: January 2012
Cloud computing has emerged as a new model for service delivery and along with it several issues, most related to adoption, security, and management. Earlier adopters as well as potential users are faced with many management challenges including some affecting the business; e.g., vendor lock-in, while others are related to service operations; e.g. monitoring of network, storage, and computational resources.

Sub-Carrier-Multiplexed Duplex 64-QAM Radio-Over-Fiber Transmission for Distributed Antennas

IEEE CTN Issue: January 2012
The past years have witnessed a huge increase in the number of wireless subscribers accessing the Internet from mobile devices. The proportion of high-bandwidth services, such as video-on-demand, video conferencing, voice-over-IP and internet gaming is on the rise. A major contributor to the increase in the demand for these high-bandwidth services is the development of high bitrate portable devices, such as smart-phones and tablet PCs. These mobile devices use WiFi, 3G HSPA and imminently LTE technology for communication with wireless base stations or routers. IEEE Communications Letters
