An analytical model for the Neighbor Turn Taking MAC protocol

The Neighbor Turn Taking (NTT) Medium Access Control (MAC) protocol is a loosely scheduled MAC, whose intended purpose is for use in wireless ad hoc networking environments where the node mobility is low. This protocol has been previously shown via simulation to perform better than IEEE 802.11 in terms of end-to-end packet latency and rate of successfully transmitted packets under saturated conditions. In this paper, we present an analytical model of the NTT MAC based upon the Bianchi station model of 802.11’s Distributed Coordination Function to further support the claims of previous work. When comparing the analytical model developed for the NTT MAC protocol with that of 802.11, significant improvements in access delay and the probability of successful packet transmission are shown, which will ultimately provide energy savings, while attaining a per node throughput that is consistent with 802.11.
