IEEE 802.15.4 standard defines the protocol and interconnection of devices via radio communication in a Personal Area Network (PAN). IEEE 802.15.4 standard was developed to work in all wireless environments and now-a-days, it has been increasingly use for wireless sensor network. This standard has an attractive feature for real time application by providing Guaranteed Time Slot (GTS) mechanism. By applying this mechanism this standard gives real time guaranty to deliver the time critical data. This paper explores the performance optimization of the GTS mechanism using conventional method and proposed adaptive method.
