This paper proposes and implements a wireless sensor network system with UDHR (uplink-downlink heterogeneous routing) protocol according to the characteristic of data flows in WSN. The proposed routing protocol can be applied to multi-purpose mode such as time- driven mode, event-driven mode and query mode. The simulation results show that the protocol is effective, scalable and robust. Finally the routing protocol is realized in the self- development testbed platform, which can monitor the entire network topological changes, network overhead, energy consumption of each node, data collection and so on.
