The impact of MAC service-time and route discovery time on packet queuing delay in saturated ad hoc networks
This thesis presents a quantitative analysis of packet queuing delays in saturated DCF networks. It presents the relationship between medium access control (MAC) delays, routing delays, and the packet queuing delays, in terms of MAC service-time and route discovery time. The effects of network size and data transmission rates on the queuing delays were also analyzed. The simulations reveal that the MAC service-time affects the packet queuing delay in stationary networks; whereas the route discovery time along with the MAC service-time affects the queuing delays in mobile networks. Also, the average queuing delay increased with an increase in the network sizes and data transmission rates, especially for network sizes of 20 and more.
