移动自组网的容错拓扑控制技术

对移动自组网中面临的邻居信息过时问题（包括邻居坐标过时与邻居集合过时）进行了研究，提出了保持移动自组网中任意2点之间，即K点(S点)和K路径(S路径)连通的容错拓扑控制 (MFTTC) 算法，并给出了算法有效性证明. 仿真结果表明，MFTTC在邻居信息过时的情况下仍能大大简化网络拓扑，根据K值可以调整网络拓扑容错能力，且MFTTC能够随节点最大移动速度调整网络拓扑，有助于保持移动网络的拓扑稳定性.

Fault-Tolerant Topology Control in Mobile Ad Hoc Network

Outdated neighbor information problems in mobile Ad Hoc network,including outdated neighbor coordinates and outdated neighbor sets,were studied.A localized fault-tolerant topology control algorithm MFTTC(mobile fault-tolerant topology control) was proposed,which guarantees that any two nodes in the network are both K-vertex (S-vertex) and K-paths(S-paths) connected under out-of-date neighbor information.MFTTC's validity was proved.Simulation results show that by(using) MFTTC,network topology can be simplified and by varying K,network reliability can be controlled even under outdated neighbor information.Also,the network topology could be adjusted according to the maximum speed of nodes,which is helpful to keep topology stability in a mobile network.
