摘要：

The IEEE 802.15.4 standard enables device level wireless connectivity in personal area networks. Its Medium Access Control (MAC) protocol supports the exclusive use of a wireless channel through guaranteed time! slot (GTS). However, the bandwidth underutilization problem occurs in GTSs when the used bandwidth is less than the available. In this paper, a new GTS scheme is presented to allow more devices to share the bandwidth within the same period. The evaluation and analysis reveals that the bandwidth utilization is improved.
