A new GTS allocation scheme for IEEE 802.15.4 networks with improved bandwidth utilization
Liang Lun Cheng, Anu G. Bourgeois, Xin Zhang · 2007
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.
