چکیده
The design of a high performance street lighting control system is an important issue. This paper focuses on an assessment of the performance of the ZigBee mesh and tree network topologies which, can be implemented in different street lighting control network configurations. The paper also presents the performance evaluation of three configurations in order to select the best candidate that can be integrated within a street lighting control system. The data reveal that the tree topology is much more efficient than the mesh topology. Also, the impact of the acknowledgment (ACK) communication mechanism on the network throughput and on the end-to-end delay application parameter is analyzed. Streszczenie. W artykule przedstawiono wyniki analizy działania sieci w topologii siatki ZigBee oraz drzewa, w zastosowaniu do sterowania oświetleniem ulicznym. Ocenie poddane skuteczność doboru najlepszych kandydatów do integracji z systemem oświetlenia w odniesieniu do trzech konfiguracji. Stwierdzono znacznie większą skuteczność działania struktury drzewiastej w stosunku do struktury siatki. (Ocena działania sieci ZigBee i struktury drzewiastej w systemie sterowania oświetleniem ulicznych).

متن کاملOn the Selection of Optimum Topology for QoS aware ZigBee-WiMAX Based Healthcare Monitoring System
in this work I have proposed different network architectures using OPNET which consists of combination of ZigBee and WiMAX topologies. ZigBee is used to sense the data from the human body whereas WiMAX is used as a backbone to deliver the data at the distant location using microwave links. The nee of using WiMAX with ZigBee arises as ZigBee network’s coverage area is limited to few meters. This...
