Digital Sensors and Sensor Sysstems


Abstract: This paper describes the tests carried out with a Wireless Sensor Network in order to examine the radio coverage in the large space of a university food court. Due to the challenging environment, the development of a multi-hop protocol was necessary. The protocol deems a sensor node as a repeater to extend the signal reach. We used the Radiuino open-source platform to develop the protocol with the flexibility to design an address strategy in the packet. The preliminary results indicate that the protocol developed is feasible, stable and robust.


Keywords: WSN, Multi-hop topology, Routing protocol.
