A Wireless Sensor Network for Orienteering Competitions

This thesis deals with the development of a wireless sensor node for use in orienteering competitions. The nodes are used to transmit runners’ split times from control points, usually located in a forest, to a base station in the finish area. The developed sensor node is optimized for low price and uses a 500 mW radio module to achieve the required range. TinyOS is used as a software platform, and the Collection Tree Protocol (CTP) currently handles multi-hop routing. Measurements have shown that the radio module used does not comply to its datasheet, so that the desired range cannot be achieved. Possibilities to improve the node’s performance in future work are shown.
