M-DSMA: MAC protocol using dynamic state transition of mobile stations in ad hoc networks
Description
Demand for mobile ad hoc networks (MANET) is increasing. In a MANET, mobile stations communicate with each other by autonomous distributed control. Although flooding is used for discovering a route from a source to a destination, there is the broadcast storm problem when traffic increases rapidly. Besides, there is the hidden terminal problem that packet collisions may be caused in wireless communication. For solving these problems, we propose M-DSMA (MAC protocol using dynamic state transition of mobile stations in ad hoc networks). We define two kinds of states (active state and non-active state) at the mobile station. During the active state, a busy tone is sent as the active state station detects that the channel is busy, and a stop tone is sent as the active state station detects packet collisions. By using two tones, the reachability can be improved.
