This thesis presents a quantitative analysis of medium access control (MAC) delays in saturated ad hoc networks and their impact on node packet service-time. First, the medium access delay at an ad hoc node was modeled in terms of the time spent in collisions and successful transmission. Secondly, the variations in route discovery time with respect to the variations in medium access delays were analyzed. Finally, the overall effect of MAC delay on node packet service time was discussed. In stationary networks, the routing delays are negligible after the initial route discoveries; hence MAC delays determine the packet service-time. In mobile networks, the upper layer delays associated with node transmission such as route discovery time together with MAC delay effect the node packet service-time. The simulations were carried out for stationary network scenarios, and the results support the presented model.
