ABSTRACT
Because of its ability to provide the collision-free packet transmission regardless of the traffic load, TDMA has been applied effectively in ad hoc networks. Until now, assuming a stationary ad hoc network, a TDMA slot assignment protocol which achieves the high channel utilization has been proposed. In this paper, we extend the protocol to accomodate the dynamic topology change due to the movement of nodes. In our protocol, since each node autonomously detects a change in network topology and assigns a slot to itself, the high channel utilization in the previous protocol can be kept even when nodes in a network move. Furthermore, we verify the effectiveness of the protocol by simulation experiments. The results show that our protocol improves channel utilization in comparison to conventional protocols.
