Video transmission over wireless network has to face many challenges due to varying channel conditions and limited network resources. To achieve reliable transmission as well as high throughput efficiency over lossy wireless channels, a network coding/ARQ hybrid error-control scheme is developed in this paper. Different form the traditional methods, the proposed scheme takes both the reliability and...
We devise an adaptive fault-tolerant scheme based on the exponentially weighted moving average (EWMA) which can provide fault tolerant in sensor networks and balance between traffic overhead and transmission failure. We use the multipath routing to transmit packets, and according to wireless network environments we adaptively change the required number of paths for transmission. So it can achieve...
