| 摘 要： | 在节点的移动规律无法预知的情况下，针对“移动空间（MobySpace）”中DTN（Delay Tolerant Network）概率路由算法中节点预先定位问题，提出了一种自我定位方案。该方案能够在节点移动的过程中根据一个修正因子不断对节点坐标进行调整，最后使坐标收敛到一个可用的范围。实验证明，该方案可以通过一个合适的修正因子确保路由算法具有很好的稳定性和可移植性。

| Abstract: | Probabilistic route algorithm of DTN（Delay Tolerant Network） in “MobySpace” needs to locate the node in advance. But it is hard to know in advance how a node moves. A scheme of self-location, in which all coordinates of a node are adjusted gradually by a adjusting parameter while the node is moving, is proposed in this paper. Finally all coordinates will fluctuate in a usable range. The simulation shows that the scheme is able to find a proper value of adjusting parameter to make the routing algorithm in DTN stable and transplantable. |
