Quantitative analysis of frame inter-arrival times in saturated ad hoc networks

Abstract

Medium Access Control (MAC) delays increase the frame inter-arrival time on the destination node in saturated ad hoc networks. With the increase in the network size more and more nodes contend for the medium which increases the collisions and drops affecting the frame inter-arrival time. High frame inter-arrival rates result in a queue overflow at the destination node and low frame inter-arrival rates increase the packet end-to-end delay. The variable parameters in the simulations are the network size and the data rates for the transmission. It is observed with simulations that the average frame inter-arrival time increases with the increase in the number of contending nodes in a saturated ad hoc network.
