Quality of Service support in MANET is a challenging and difficult due to the dynamic nature of the ad hoc network, nodes may leave, and join the network or move around at anytime. In order to support certain level of service quality, a mechanism for recourses allocations/reservation has to be implemented to provide the needed assurance for the desired level of quality.However, in such a mobile environment (unlike networks with fixed topology), no service guarantee can be assured by any reservation/allocation mechanism and all what those mechanisms can offer is a better chance or a promise for better service. Several mechanisms have been developed, they differ in the level of assurance they can provide ranging from no assurance to relatively high level of assurance.In this paper, we present a survey of the current research that has developed to address the problem. Some of those mechanisms are, DiffServ, DSRRSVP, DRSVP and MRSVP. We also compare them based on certain criteria (complexity, scalability, level of assurance, control overhead, and types of environments that they support).
