In this paper, we propose a novel Qos guaranteed scheme, called Dynamic GTS (Guaranteed Time Slot) allocation Algorithm, for mobile users'; real-time applications in wireless sensor networks with IEEE 802.15.4 standard. The fundamental idea is that networks reserve time slots for the mobile users to access, transmission and receiving. To estimate the mobile users'; movement state, an extended Kalman filter model is used. Then, we employ the proposed allocation algorithm with the predicted information to reserve resources. Simulation results show that the introduced algorithm can improve the connectivity and system reliability in mobile wireless sensor network.
