Cooperative Error Control Mechanism Combining Cognitive Technology for Video Streaming Over Vehicular Networks

Abstract

Video streaming over vehicular networks is an attractive feature to many applications, such as emergency video transmission and inter-vehicle video transmission. Vehicles accessing road-side units have a few seconds to download information and experience a high packet loss rate. Hence, this paper proposes Cooperative Error Control (CEC) mechanism combining Cognitive Technology (CT) for video streaming over wireless vehicular networks. CEC mechanism combining CT uses a cooperative error recover scheme to recover lost packets not only from a road-side unit which uses the primary channel but also from the other vehicles using a free channel. Hence, CEC mechanism with CT can enhance error recovery performance and quality of video streaming over vehicular networks. Simulation results show the error recover performance of the CEC mechanism combining CT performs better than the other related mechanisms.

“…The protocol stacks of the DSRC are illustrated in Figure 2. More detailed information is provided on the concepts of the DSRC protocol stacks information (IEEE, 2006(IEEE, , 2010a(IEEE, , 2010b(IEEE, , 2011Tsai, Chilamkurti, & Li, 2011) and they are described below. In the DSRC physical layer, the main modifications involve a number of channels, channel bandwidths, and modulation coding schemes.…”
