Abstract :
The WSNs (Wireless Sensor Networks) is a network technique for the implementation of Ubiquitous computing environment. The GTS (Guaranteed Time Slot) of the IEEE 802.15.4 standard, which is the contention free access mechanism, is used for low latency applications or applications requiring specific data bandwidth. The current standard GTS allocation scheme uses FIFS (First In First Service) scheduling. So it reduces the emergency data transmission reliability and has problems. In this paper, we design a GTS allocation scheme for emergency data transmission in cluster-tree WSNs. The proposal scheme using the EDG (Emergency Data Slot) decreases the transmission delay and increases the packet throughput, so the emergency data transmission is more efficient than the current standard.
