Target tracking is one of the important topics in wireless sensor network (WSN) research. Monitoring enemy intrusions, surveilling wildlife animals and tracking specific people are examples of target tracking. Target Tracing needs to track and collect information about monitoring targets. Many solutions of using WSNs to perform target tracking have been proposed in the research. A common method is to wake up the sensors in a WSN in a predictive manner and only needs to activate a few sensors that could track the next step of a target. However, target tracking requires a trade-off between accuracy and energy saving. In order to save the energy of sensors, the number of wakeup sensors may be too small and the prediction itself is thus uncertain. On the hand, the sensors may consume too much energy in order to ensure that the target is not lost. In this paper we propose a tracking target method called Hexagonal Routing Repair Procedure (HRRP). The method uses regular hexagons to tessellate the entire sensing area and the sensors route the sensor information back to the base station through Hexagonal Hierarchy. The target`s current position and maximum speed can be used to calculate the target`s possible range of motion, and we only need to wake up the nearby hexagonal cluster to track targets, and thus saving energy as well as preserving the accuracy.
