For wireless ad hoc networks, routing is much more complex than in traditional wireless systems, due to the lack of centralized control, infrastructure less nature and knowledge of a predetermined topology. The infrastructure less nature of MANETs makes it difficult to ensure the reliability of packet delivery over multi-hop routes. So, end to end delay in packet delivery is an important QoS metric in ad-hoc network routing. End-to-End delay comprised of delay involved in transmission, propagation and processing. Estimation of end to end packet delay in mobile ad-hoc network is complex because it depends on many influential factors as path length from source to destination, average neighbors of intermediate hops, link expiration time, mobility, bandwidth and interference etc. This paper focusses on different methods adopted by different scientists for estimation and prediction of delay
