Cross-layer Optimization for Video Streaming over Wireless Multimedia Sensor Networks
This paper proposes a cross-layer optimization method for video streaming over Wireless Multimedia Sensor Networks (WMSNs). It is based on an algorithm that dynamically maps MPEG-4 video packets to 802.11s appropriate access categories. In 802.11s mesh networks, packets are differentiated and higher priorities are given to forward packets. When queue length of AC2 fills up, forward packets are remapped to lower access category AC1. The simulation results show that this optimization method can improve the performance of forward video sequences.
