The protocols of Wireless Sensor Networks (WSNs) can be categorized into two classes: proactive network protocol like CTP and reactive network protocol like TEEN. The former periodically collects data, working well in the applications of collecting data persistently. However, it can’t dynamically alter the transmission frequency and the routing selecting strategy. The latter can react to the environment change, so it is widely used in the applications requiring nodes to be reactive to some emergencies. But it only works in reactive networks without collecting data under normal circumstance. We find that dynamically altering the transmission frequency and the routing selecting strategy according to the environment change is very effective and significant. For the reasons above, this paper presents TDRHN protocol. It periodically collects data in normal situation and can not only take faster transmission frequency but also alter the routing selecting strategy when it detects some emergencies. So TDRHN can effectively work in hybrid networks combining proactive networks and reactive networks. Finally, we evaluate TDRHN on the testbed with TelosB motes in real deployment. The concluded results of the experiments demonstrate that TDRHN has some particular advantages.
