In this paper we propose a multipath routing algorithm (EDB-MRA) on the basis of Directed Diffusion for wireless sensor networks. The algorithm establishes multiple paths from source node to destination node. According to the three metrics of network link - energy consumption, delay and bandwidth, each path can be given a choices probability to make data always transmit on multiple paths of better link performance. At last, we simulate the new multipath routing algorithm on the NS2, and make an analysis and compare with DD and HREEMR routing algorithm. The simulation result indicates that the new routing algorithm shows a good performance on node average energy consumption, average transmission delay and packet delivery rate.
