QoS and channel aware packet bundling for VoIP traffic in cellular networks
(IEEE, 2009-09-16)
We study the problem of multiple packet bundling to improve spectral efficiency in cellular networks. The packet size of real-time data, such as VoIP, is often very small. However, the use of time division multiplexing ...
Using RTT Variability for Adaptive Cross-Layer Approach to Multimedia Delivery in Heterogeneous Networks
(IEEE, 2009-10)
A holistic approach should be made for a wider adoption of a cross-layer approach. A cross-layer design on a wireless network assumed with a certain network condition, for instance, can have a limited usage in heterogeneous ...
NQAR: Network Quality Aware Routing in Error-Prone Wireless Sensor Networks
(2009-11-10)
We propose a network quality aware routing (NQAR) mechanism to provide an enabling method of the delay-sensitive data delivery over error-prone wireless sensor networks. Unlike the existing routing methods that select ...
