Dual Probability Selection Mapping Algorithm for Video Transmission over Wireless Sensor Networks

The video stream transmission over wireless sensor networks is specially required to consider the Quality of Service (QoS), such as low packet loss, low latency and high Peak Signal-to-Noise Ratio (PSNR). In order to improve the performance above, the authors propose a novel video transmission solution, named Dual Probability Selection Mapping Algorithm (DPSMA). In this solution, by analyzing different video frames for the importance of decoding and combining with the IEEE 802.11e Enhanced Distributed Channel Access (EDCA) mechanism, the DPSMA allocates different mapping probabilities for different video frames.
