The personal area network (PAN) coordinator can assign a guaranteedtime slot (GTS) to allocate a particular duration for requested devices in IEEE802.15.4 beacon-enabled mode. The main challenge in the GTS mechanism ishow to let the PAN coordinator allocate time slot duration for the devices whichrequest a GTS. If the allocated devices use the GTS partially or the traffic patternis not suitable, wasted bandwidth will increase, which degrades the performanceof the network. In order to overcome the abovementioned problem, this paperproposes the Partitioned GTS Allocation Scheme (PEGAS) for IEEE 802.15.4networks. PEGAS aims to decide the precise moment for the starting time, theend, and the length of the GTS allocation for requested devices taking intoaccount the values of the superframe order, superframe duration, data packetlength, and arrival data packet rate. Our simulation results showed that theproposed mechanism outperforms the IEEE 802.15.4 standard in terms of thetotal number of transmitted packets, throughput, energy efficiency, latency,bandwidth utilization, and contention access period (CAP) length ratio.
