In this paper, we propose two Bluetooth MAC scheduling schemes which can support more than 7 nodes simultaneously. One is MARS (Multiple Active Round Scheduling) scheme which allows only one time slot to each node every round in a frame and the other is MASS (Multiple Adaptive Slot Scheduling) scheme which allocates multiple time slots according to an amount of backlogged packets in the queue of a sensor node. This feature makes it possible that Bluetooth system can serve efficiently various

And these also can be operated using the park mode to increase the number of nodes to access. We present the performance comparison of the proposed schemes with the conventional Bluetooth system in terms of energy efficiency, service delay, and throughput, etc. by computer simulations.
