Seni bina rangkaian ZigBee memfokuskan pada pembangunan kos rendah, komunikasi berkelajuan rendah di mana-mana antara peranti. Teknik ZigBee adalah berdasarkan IEEE 802.15.4, yang menentukan lapisan fizikal dan kawalan akses sederhana (MAC) untuk rangkaian kawasan peribadi wayarles kadar rendah (LR-WPAN). Pada masa ini, banyak rangkaian penderia wayarles telah menyesuaikan standard terbuka ZigBee untuk membangunkan pelbagai perkhidmatan bagi menggalakkan kualiti komunikasi yang lebih baik dalam kehidupan seharian kita. Masalah kebolehpercayaan sistem dan rangkaian dalam menyediakan perkhidmatan yang stabil menjadi lebih penting kerana perkhidmatan ini akan dihentikan sekiranya kebolehpercayaan sistem dan rangkaian tidak stabil. Piawaian ZigBee mempunyai tiga jenis rangkaian; bintang, pokok dan jaringan. Kertas tersebut memodelkan susunan protokol ZigBee daripada lapisan fizikal ke lapisan aplikasi dan menganalisis kebolehpercayaan lapisan ini dan masa min untuk kegagalan (MTTF). Penggunaan sumber saluran, peranan peranti, topologi rangkaian dan objek aplikasi digunakan untuk menilai kebolehpercayaan dalam lapisan fizikal, kawalan akses sederhana, rangkaian dan aplikasi. Dalam rangkaian bintang atau pokok, sistem siri dan teknik gambarajah blok kebolehpercayaan (RBD) boleh digunakan untuk menyelesaikan masalah kebolehpercayaan mereka. Walau bagaimanapun, teknologi pembahagian digunakan di sini untuk mengatasi masalah kerana kerumitan rangkaian lebih tinggi daripada yang lain. Rangkaian jaringan menggunakan teknologi bahagian dikelaskan kepada beberapa sistem siri tidak boleh dikurangkan dan sistem selari tepi. Oleh itu, kebolehpercayaan rangkaian mesh mudah diselesaikan menggunakan sistem siri-selari melalui skim yang dicadangkan kami. Keputusan berangka menunjukkan bahawa kebolehpercayaan akan meningkat untuk rangkaian mesh apabila bilangan tepi dalam sistem selari meningkat manakala kebolehpercayaan dengan cepat menurun apabila bilangan tepi dan bilangan nod meningkat untuk ketiga-tiga rangkaian. Lebih banyak penggunaan sumber adalah satu lagi kesan faktor terhadap penurunan kebolehpercayaan. Walau bagaimanapun, kebolehpercayaan rangkaian yang lebih rendah akan berlaku disebabkan oleh kerumitan rangkaian, lebih banyak penggunaan sumber dan hubungan objek yang kompleks.

Abstract: The architecture of ZigBee networks focuses on developing low-cost, low-speed ubiquitous communication between devices. The ZigBee technique is based on IEEE 802.15.4, which specifies the physical layer and medium access control (MAC) for a low rate wireless personal area network (LR-WPAN). Currently, numerous wireless sensor networks have adapted the ZigBee open standard to develop various services to promote improved communication quality in our daily lives. The problem of system and network reliability in providing stable services has become more important because these services will be stopped if the system and network reliability is unstable. The ZigBee standard has three kinds of networks; star, tree and mesh. The paper models the ZigBee protocol stack from the physical layer to the application layer and analyzes these layer reliability and mean time to failure (MTTF). Channel resource usage, device role, network topology and application objects are used to evaluate reliability in the physical, medium access control, network, and application layers, respectively. In the star or tree networks, a series system and the reliability block diagram (RBD) technique can be used to solve their reliability problem. However, a division technology is applied here to overcome the problem because the network complexity is higher than that of the others. A mesh network using division technology is classified into several non-reducible series systems and edge parallel systems. Hence, the reliability of mesh networks is easily solved using series-parallel systems through our proposed scheme. The numerical results demonstrate that the reliability will increase for mesh networks when the number of edges in parallel systems increases while the reliability quickly drops when the number of edges and the number of nodes increase for all three networks. More use of resources is another factor impact on reliability decreasing. However, lower network reliability will occur due to network complexity, more resource usage and complex object relationship.
