A MicroBlaze based WSN sink node using XBee transceiver

The wireless sensor network (WSN) represent a fertile area for research and exploration, especially with the enormous development in modern electronic systems, where it becomes an alternative to traditional wired systems. The wireless systems are less energy-consumptive and inexpensive, in addition, it helps to reduce the complexity of wiring. Wireless sensor networks require the design of high density computing, an energy-efficient and a flexible node architecture. In this paper, we propose an architecture for the Sink node based on MicroBlaze soft-core processor, and XBee communication module for communication. The proposed node was tested and implemented on the Digilent Basys3 Artix-7 FPGA board. A simple application of temperature measurement has been developed as a test to ensure the proper functioning of the Sink node.
