Efficient SVC frame dropping using CLPA algorithm over multihop WSNs

摘要

A multihop wireless sensor network carrying adaptive low bit-rate video stream is to be considered. Using a novel cross-layer adaptive prioritization algorithm, denoted by CLPA, a thorough analysis of the composition of the frames being carried or dropped over the network is to be conducted. The results show how the used prioritization scheme, which favors the basic frames over the enhancement frames, has intelligently changed the constituency of the received frames in a way that created a noticeable improvement in the quality of received video stream.
