On the TDMA with imprecise propagation delay information

Abstract

In this paper, I study the receiver synchronized time division multiple access (TDMA) in the presence of propagation delay deviation, which is one of the major parameter to consider for underwater wireless sensor networks. First I describe how the receiver synchronized TDMA protocol can be used in a network without propagation delay deviation. Then I modify the receiver synchronized TDMA to get higher utilization in the presence of propagation delay deviation. I analyse this modified TDMA protocol using discrete time markov chain. Further I find the optimum parameters to get the maximum frame utilization. All analytical results are verified by simulation based results.
