摘要：Mobile Ad-Hoc networks (MANETs) are collection of mobile nodes that dynamically forming a temporary network without preexistingnetwork infrastructure and communicate with its neighbors to perform peer to peer communication and transmission. It offers unique benefitsand versatility for certain environments and certain applications. Since there is no prerequisite fixed infrastructure and base stations, they can becreated and used anytime, anywhere. Propagation models focused on predicting the average received signal strength at a given distance from thetransmitter, as well as the variability of the signal strength in close spatial proximity to a particular location. The accuracy of any particularpropagation model in any given condition will depend on the suitability among the constraints required by the model and depend on terrain. Anumber of propagation models like Free Space and Two Ray ground have been exist. In this paper, we present comparative study on thebehavior of various routing protocols with path loss propagation models, various performance metrics used for this comparison such as packetdelivery fraction, average jitter, throughput and average end to end delay. The studies would be helpful in choosing the correct protocol for anyactive operating environment.
