Wireless Sensor Network (WSN) is an important part of the Internet of Things, The design of routing strategies is very important as well in WSN just like in Ad hoc. The paper firstly describes the characteristics of WSN routing protocols; Secondly analyzes in details the AODV which is the typical on-demand routing protocol in Ad hoc, transplants it into WSN and proposes the transition method of adaptive clustering routing and routing transition; and finally scheme out a new adaptive hierarchical routing transition protocol BCRP of high efficiency and integrity. After doing simulation test, it is found out the adaptability and extensibility of BCRP significantly improved.
