Abstract
The IEEE 802.15.4 is designed for wireless personal area networks. Indeed, wireless personal area network turns out to help greatly in maintaining a flexible mode of communication within limited area networks. It is in this context that our present study can be set, in which the beacon-enabled mode is enabled with cluster tree topology to reach the scope of a rather extended network, whereby the network turns out to be clustered into several subgroups. Every single subgroup is characterized by its specific duty cycle which is configured by its correspondent personal area network coordinator. Therefore, many modes are enabled in the same network. Based on a very special mathematical model developed by us for energy consumption, the personal area network coordinator detects the actual level of energy in the battery of node. Then, an interesting comparison is made with the multiple thresholds which are already set. After that, both beacon order and superframe order (the standard IEEE 802.15.4 parameters) are recomputed with reference to the remaining energy.

For the adaptive algorithm to optimize the dynamics (AAOD) approach, our method describes the best results in the end-to-end parameter in addition to the reception and the collision states
Every subgroup turns out to be characterized with special IEEE 802.15.4-associated parameters (BO, superframe order (SO))
Summary
The Internet of things (IoT) has recently been established as a common terminology, frequently applied in the field of technology. Energy constitutes the most serious trouble encountered by most of the wireless-based modes of communication, including the wireless personal area network (WPAN) family, formed of both physical and MAC layers As it is the case with the ZigBee technology, its associated nodes could be of either an FFD or an RFD in type. The MAC layer is mainly responsible for maintaining the beacon transmission process, in addition to managing the guaranteed time slot (GTS) and fulfilling the crucial role of ensuring the data transmission security.16 In this respect, the IEEE 802.15.4 technology helps provide two modes of activities: the beacon-enabled mode and the non-beacon-enabled mode. Based on the canal status, a relevant appropriate decision is taken. either relevant data will be transmitted or an extra short-span duration is awaited, for a potentially possible appropriate canal availability to be checked
