Video streaming over wireless networks is compelling for many applications, ranging from home entertainment to surveillance to search-and-rescue operations. Interesting technical challenges arise when the unpredictable nature of the wireless radio channel meets the requirements of high data rate and low latency for video transport. In this paper Quality of Service (QoS) guaranteeing scheme for video transmission over WSN, called the Multi-Channel Multi-Path (MCMP) scheme is proposed. It selects the best paths from the source camera to the gateway based on multiple Quality of Service metrics such as hop-count, aggregated path energy and end-to-end delay. A failure recovery scheme is also provided to cope with link failure. It uses H.264 protocol for video encoding and decoding and can be used as a compressor. Here frames are transmitted based on priorities. Network simulation reveals that this proposed scheme significantly outperforms the existing scheme in terms of channel utilization and delay.
