|Abstract:||Robust image transmission service over mixed wired and wireless network constitutes a significant challenge due to limited bandwidth, error prone, and time varying characteristics of wireless radio channel and highly dynamic nature of heterogeneous network topology. The latest JPEG-2000 image standard provides efficient and flexible image compression based on coding image into multiple quality layers. This paper presents the multi-quality transmission scheme in distributed network architecture for robust transmission of JPEG-2000 images over peer-to-peer mixed wired and wireless link The network is ad-hoc in nature with each peer within the network sensing each other for best effort image transmissions. Experiments over various distributed mixed wired and wireless network topologies have shown that this scheme guarantees successful image transmission as long as good links are available among peers even though the direct link between initiating and destination peers may be congested or broken. The scheme improves end-to-end processing time when more intermediate peers are available in the network. The advantages of employing multiple layer image transmission are 1) to allow the non-initiating peers to participate in the image routing to share the additional bandwidth with fair QoS support, which is especially beneficial in the low bandwidth network involved architecture, such as GPRS, and 2) to provide cost-effective solutions for visual communications among ad-hoc mobile peers with smaller screen-size and lower processing power. © 2005 IEEE.|
