Cross-Layer Optimized Wireless Multimedia Communications

Recent advances in wireless and mobile communications provide ample opportunities for introducing new services. Supporting multimedia applications and services over wireless networks is challenging due to constraints and heterogeneities such as limited battery power, limited bandwidth, random time-varying fading effect, different protocols and standards, and stringent Quality-of-Service (QoS) requirements. Cross-layer design methodologies provide great promises for addressing these challenges and achieving reliable and high-quality end-to-end performance in wireless multimedia communications. In this special issue on crosslayer wireless multimedia communications, the authors have accepted a few papers that address such issues.
