Performance Analysis of Beacon Enabled IEEE 802.15.4 Using GTS in Zigbee
نویسندگان
چکیده
The current IEEE 802.15.4 standard restricts the beacon enabled approach to star networks, while they support multi-hop networking in mesh but with no synchronization. In this paper there is proposal of a distributed IEEE802.15.4 MAC modification to improve GTS usability in cluster networks. Location of BOP in inactive period with Virtual GTS is proposed and throughput is observed for chain topology. KeywordsGTS, Beacon Only Period(BOP), MAC,PNC

Wireless networked control system using ZigBee/IEEE 802.15.4
In this paper, the use of wireless sensor networks for networked control loop is analyzed. As the non beacon-enabled mode of IEEE 802.15.4/ZigBee does not ensure the stability for the control loop since non mechanism can prevent the perturbation coming from other applications sharing the same network, the quality of control has to be guaranteed for the control loop. Several possible solutions a...

In this paper, the suitability of wireless sensor networks for networked control loop is shown. As the non beaconenabled mode of IEEE 802.15.4/ZigBee does not ensure the stability for the control loop since non mechanism can prevent the perturbation coming from other applications sharing the same network, we investigate the beacon-enabled mode using the Guaranteed Time Slot (GTS) mechanism and ...
