In this paper, a brief review of most conventional routing protocols for mobile Ad- Hoc networks has been conducted, moreover Dynamic Source Routing (DSR) protocol has been discussed with more details. The focuses on both route discovery and route maintaining phases as the main part of DSR protocol have been done and simulated in this paper. Random movement pattern for mobility of nodes have been assumed with random walk model. Also, negative exponential random model for time duration of a call. In addition with letting poisson distribution of a call demand, are assumed as the main problem definitions. Two main performance indices namely, call blocking and forced termination probabilities as constraints have been introduced. The above two indices for different loads and moving velocities have been simulated. In order to show the effects of Ad- Hoc routing protocol on service quality. Two type of direct and indirect path servicing have been studied. Results shows that a multi loop path introduces lower blocking and forced termination rates.
