摘　　要：到达时间差算法(TDOA)是通过测量移动节点接收两个已知节点发射信号的时间差值估算距离,但移动节点需在通信范围内;DV-hop根据节点之间跳数测距,但估算误差较大。将两种方法相结合,在不增加网络硬件的条件下,提高了定位精度。Time Difference of Arrival （TDOA） algorithm is used to estimate the distance with the time difference of transmitting signals between the two receiving nodes but the nodes should be in the range of communication, while the DV-hop algorithm is applied to predict the distance according to the numbers of hop but with more error. We combine the two to obtain the high position accuracy under the same hardware environment,
