According to the characteristics of wireless sensor network link with video transmission instability and poor reconstruction quality, this paper proposed an reliable transmission of routing algorithm (EDLOR) which is adaptive to Multiple Description Coding (MDC). Firstly, it took fully consideration about the video coding rate, delay-constrained, network packet loss and other factors. Secondly, it aimed at how to optimize multiple description of the Peak Signal-to-NoiseRatio (PSNR). As a result, the overall video distortion minimization was gained. Thirdly, these MDCs would be assigned to designed path for transmission according the computed results. It is shown from experimental results that EDLOR can improve the overall video quality through promoting the average PSNR and lowering packet loss rate.

Secondly, it aimed at how to optimize multiple description of the Peak Signal-to-NoiseRatio (PSNR). As a result, the overall video distortion minimization was gained. Thirdly, these MDCs would be assigned to designed path for transmission according the computed results. It is shown from experimental results that EDLOR can improve the overall video quality through promoting the average PSNR and lowering packet loss rate.
