Ni Zi-Yun, Zhang Ling. An Optimized ZigBee Routing Algorithm Based on Adaptive Cluster Mechanism[J]. 2015, 32(4): 105-111.DOI: 10.3969/j.issn.1007-7162.2015.04.019.
ZigBee protocol uses the combination of AODVjr and Cluster-Tree algorithm as its own routing algorithm (ZBR). But the routing algorithm does not combine the advantages of both ones so it leaves little possibility to improve the performance of network. In order to solve the problem
this paper proposes an algorithm which combines the advantages of AODVjr and Cluster-Tree routing algorithm
i.e. ACZBR algorithm. This algorithm uses Cluster-Tree algorithm within cluster and uses AODVjr algorithm between clusters. Meanwhile
in order to avoid dead nodes caused by excessive energy consumption of cluster-head nodes
this algorithm uses a cluster-head adaptive switching strategy to ensure the network performance. The simulation result shows that the ZBR algorithm has greatly improved the performance of network lifetime
