Improvement of bluetooth technology scheduling algorithm for wireless personal area network

In order to improve the efficiency of wireless personal area networks. It is necessary to study how to allocate the limited bandwidth of wireless networks and how to access the network at each terminal. Therefore, a fully and effectively improve the utilization of wireless channel media access protocol MAC is particularly important. The improved protocol to improve its performance and can satisfy the real-time demand of QoS services based on business priorities. With the continuous improvement of Bluetooth technology and the continuous expansion of its application field. Bluetooth technology has gradually developed into a wireless communication standard for personal local area networks. Its business from the initial large number of data services into a video and voice-based real-time business. In this paper, on the basis of two level priority control polling system, a scheduling algorithm based on service priority is proposed. The experimental results show that the improved Bluetooth MAC protocol not only has better transmission performance, but also improves the average information packet and average delay than the traditional polling scheduling algorithm.
