ADAPTIVE TRANSMISSION SYSTEM AND METHOD FOR LOW DELAY/HIGH DEFINITION, AND STORAGE THEREOF

摘要

The present invention relates to an image transmission technology and, more particularly, to an adaptive system and method for effective low delay and high definition image transmission between distributed image sensor nodes in a wireless sensor network including the distributed image sensor nodes. According to the present invention, each of the nodes selects a relaying scheme that is capable of achieving a low delay and high definition performance in an adaptive manner in an inter-communication protocol of the wireless sensor network, and image information processing for low delay is performed in an intra-processing protocol, and thus effective application is possible when rapid and accurate image information transmission is required in a wireless sensor network environment.
