This paper presents a cross-layer QoS dynamic codeword routing (CLQDCR) algorithm for Wireless Multimedia Sensor Networks. It combines the advantages of AODV(Ad-hoc Distance Vector) and DCR(Dynamic Codeword Routing). Basing on the principle of cross-layer, the protocol adapt delay ,interference and energy as QoS metrics, and provide Differentiated Services for Real time Multimedia streams and delay-tolerant Data. By presenting and analyzing simulation results, the CLQDCR is shown to result in good performance of end-to-end delay and payload balancing.
