A performance study of ZigBee wireless sensors network topologies for street lighting control systems

In order to reach a high performance level in a street lighting control system, two important aspects must be taken into account: the selection of the adequate communication protocol, on the one hand, and the selection of the network topology that supports the architecture, on the other hand. Given these circumstances, the present paper focuses on an assessment of the performance of the mesh and tree network topologies which, along with the ZigBee communication protocol, can be implemented in a street lighting control architecture. As a result of the simulations that have been conducted, the data reveals that the tree topology is much more efficient than the mesh topology. This outcome arises from the analysis of the throughput, of the end-to-end delay application and of the performed number of hops.
