A arquitetura das redes ZigBee concentra-se no desenvolvimento de comunicação onipresente de baixo custo e baixa velocidade entre dispositivos. A técnica ZigBee é baseada no IEEE 802.15.4, que especifica a camada física e o controle de acesso ao meio (MAC) para uma rede de área pessoal sem fio de baixa taxa (LR-WPAN). Atualmente, inúmeras redes de sensores sem fio adaptaram o padrão aberto ZigBee para desenvolver diversos serviços que promovam a melhoria da qualidade da comunicação em nosso dia a dia. O problema da confiabilidade do sistema e da rede no fornecimento de serviços estáveis tornou-se mais importante porque esses serviços serão interrompidos se a confiabilidade do sistema e da rede for instável. O padrão ZigBee possui três tipos de redes; estrela, árvore e malha. O artigo modela a pilha de protocolos ZigBee desde a camada física até a camada de aplicação e analisa a confiabilidade dessas camadas e o tempo médio até a falha (MTTF). O uso de recursos de canal, a função do dispositivo, a topologia de rede e os objetos de aplicação são usados para avaliar a confiabilidade nas camadas física, de controle de acesso ao meio, de rede e de aplicação, respectivamente. Nas redes em estrela ou em árvore, um sistema em série e a técnica de diagrama de blocos de confiabilidade (RBD) podem ser usados para resolver seu problema de confiabilidade. Porém, uma tecnologia de divisão é aplicada aqui para superar o problema porque a complexidade da rede é maior que a das demais. Uma rede mesh usando tecnologia de divisão é classificada em vários sistemas em série não redutíveis e sistemas paralelos de borda. Conseqüentemente, a confiabilidade das redes mesh é facilmente resolvida usando sistemas série-paralelo através do esquema proposto. Os resultados numéricos demonstram que a confiabilidade aumentará para redes mesh quando o número de arestas em sistemas paralelos aumentar, enquanto a confiabilidade cairá rapidamente quando o número de arestas e o número de nós aumentarem para todas as três redes. O maior uso de recursos é outro fator que impacta na diminuição da confiabilidade. No entanto, ocorrerá menor confiabilidade da rede devido à complexidade da rede, maior uso de recursos e relacionamento complexo entre objetos.

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.
