Wireless network monitoring systems based on wireless sensor networks have wide application prospects. Generally speaking, the topological structure of such systems can be described as tree topology. The numerous existing wireless sensor network routing protocols are too complex and redundant for such systems. Therefore, this paper proposed an active wireless sensor network routing algorithm based on tree topology. The algorithm mainly includes functions such as routing establishment, routing maintenance and routing selection and so on. Firstly, the proposed algorithm can reduce network energy consumption because of the reduced communication traffic between nodes. Secondly, the proposed algorithm has some ability of fault tolerance and robustness. At last, the proposed algorithm is easy to realize and has some ability of extensibility. The proposed algorithm is particularly suitable for the numerous wireless monitoring systems and has certain practical application value.
