Abstract: This paper proposes a new routing algorithm based on the reversed path multicast tree scheme without total information of the network. By using the algorithm, different types of sensed data are transferred with different routing strategies. The simulation and the experimental results show that the wireless sensor network can work with less energy and little delay by using the algorithm.
