Abstract
AbstractMajor challenging issue in H‐MANETs (Heterogeneous Mobile Ad hoc Networks) is video transmission because it gets affected due to various factors like dynamic change in topology, interference, node mobility, collusion, and so on. Periodic connection is caused by the topology dynamic change, which leads to significant packet loss. Advancements provide the technical basis for video streaming over H‐MANETs in wireless networking and mobile devices. And efforts to achieve video transmission via H‐MANETs have run into some barriers, which have been overcome in various ways. Nonetheless, H‐MANETs are essential to provide video transmission certainty and quality provisioning. Due to the limited resources, the unreliability of wireless links, node mobility, and heterogeneity, establishing video streaming or enabling real‐time multimedia applications over H‐MANET with acceptable QoS (quality of service) poses several issues. The article's main goal is to survey QoS‐based video transmission in H‐MANETs. This study discusses the video transmission method in H‐MANET and the importance of the QoS that may be used for video transmission in H‐MANET. Various routing protocols and existing methodologies to improve QoS for video transmission in H‐MANET are discussed. In addition, the impact of delay in video transmission over H‐MANET has been discussed. Several obstacles and issues have been highlighted in providing QoS for video transmission in H‐MANET. From 2013 to 2021, a systematic literature review (SLR) is done for QoS‐based video transmission in the H‐MANET. This survey systematically gives the technical direction for research on QoS‐based video transmission and discusses potential future aspects.
