QoS for Video Transmission in MANETs: ASurvey
Prachi Gupta, Vinay Rishiwal, P.S. Kulkarni, Zubair Iqbal · 2018
A Mobile Ad hoc network (MANET) is a randomly setup network. It has no particular infrastructure. The nodes which come in the transmission range of each other can communicate directly. So, to communicate with a distant node, nodes work in multi-hop fashion. In MANETs, nodes can continuously move and so routes often get disconnected. Thus transmission of data and specially video data becomes a very challenging task due to the such known features of MANET nodes viz., mobility, limited bandwidth, constrained energy etc. But still MANETs are required to support video transmission with some provisioning of guarantee and quality.This paper presents a survey of the current research related to the QoS provisioning for video streaming in MANET. We also discuss the preliminary concepts involving QOS, coding methods and challenges in providing QoS in a MANET. We analyze what are the optimum parameters for video transmission and suggest areas for future work.
