An ad hoc network is an infrastructureless network in which nodes perform terminal as well as routing functions. A routing protocol is the only substitute to complete the communications in the absence of an access point. In spite of that mobile nodes or so called routers uses some mechanism for calculating the best route when it has multiple routes for the same destination. On the basis of one or more metrics routes are ranked from best to worst. But, in an ad hoc network many factors can affect this decision, such as the delay, load, route lifetime etc. Thus, measuring and finding routes on the basis of crisp mathematical model for all these attributes is complicated.
